Would you use the new male contraceptive?
Injection being administered
A male contraceptive which suppresses sperm production reliably and reversibly has been tested and deemed 100% effective.

Researches from the Anzac Research Institute, Sydney, Australia gave the treatment to a relatively small sample of 55 men for a year. None of their partners became pregnant.

The reversible treatment works by making use of the body's own natural system which is involved in initiating puberty.

Once treatment was stopped, normal fertility levels returned within a few months.

The treatment is a combination of an implant under the skin and injections -meaning men do not have to remember to take a pill every day.

What do you think about the new male contraceptive? Do you think your partner would use it?

No Hormones In My body. Condoms are better, ergonomic and safer also considering the Aids factor.
Sachin, India

The male pill is the answer to a million honest guys prayers
Steve, UK
What a funny world some people live in; concerned about "getting the blame from someone's father". You should consider the financial ruin imposed on a biological father by the State when a female decides that she wants someone else to pay for her child. The male pill is the answer to a million honest guys prayers - the dishonest ones don't have a problem either way.
Steve, UK

Isn't it wonderful to live in a conracepting world when our very heritage our very future are contracepted out before they even exist. There is something very, very wrong with this attitude as there is nothing more wonderful than bringing forth children. It certainly beats all the other so called alternative lifestyles!
Bob, GB

Good question, but would any woman believe a man who says he has taken it? Provided we are faithful to our partners yes....but I doubt any woman would believe a man who merely says he's had it....or would they?
Richard Sweetman, England

I have just had a baby, i have a problem with the pill, have an allergy to condoms. I think it would be wonderful if my husband was able to look after the contraceptive side for us, and he agrees.
Kat, England

I would not have a problem using a male contraceptive in this form. However, condoms provide double safety - prevent pregnancy as well as prevent sexually transmitted diseases. For the time being, considering the enormous number of teenage pregnancies in Thailand, I am perfectly happy using the condom to make absolutely sure.
Victor D., Thailand

No way. I would never let my wife to go on the pill because it is hormonal. I would not either.
Yury, NY, USA

Get Side affects? Join the club, welcome to our world!
Lorraine, Bucks
Hurray at last women can no longer get the blame from father who say "but she said she was on the pill" Guys if you don't want babies take the pill! Get Side affects? Join the club, welcome to our world!
Lorraine, Bucks

Well, no, neither I nor my boyfriend will be taking it, as pregnancy isn't an issue we face. We will, though, continue to use condoms to prevent STDs, and I hope that the heterosexual community will be just as responsible. Posts on here have asked whether you'd trust a man in a bar who said he'd taken it - that shouldn't be an issue! If you're in anything other than a monogamous long-term relationship, you should be using condoms - or not sleeping with people you know nothing about - for reasons which have nothing to do with pregnancy.
Tim, UK

I simply don't understand all the feminist/sexist stuff about this: Give me the male pill and I can have sex with whomsoever I like, whenever I like, with no fear of pregnancy. It's a miracle. 30% of married people are unfaithful, and far more unmarried 'partners' are. You may not like it, but the downside to independent frames of mind, is independent frames of mind.
Steve, UK

Oh my god! I think that is a brilliant idea and all blokes should have a go. Sure I can understand if its not for you, but it will definitely put less strain on us girls. Thanks guys.
Ros, UK

For all who are concerned about side effects women have been suffering side effects not only from contraceptives but from other drugs because most drugs are tested on male animals first and on male volunteers. So stop being a wimp and worrying about minor side effects and be responsible- the boyhood days are over.
Kayla, USA/UK

I can see STD infections going through the roof within two years
H Stiles, England
This is probably the worst thing that could have been announced in light of the explosion in STDs amongst young people in both developed and developing countries. Most people don't have the cerebral capacity to understand that there's more to contraception that to preventing unwanted pregnancy. I can see STD infections going through the roof within two years.
H Stiles, England

Absolutely. Not, no, no, no, no the contraceptive has always been for women lets keep it that way.
Habib, United Kingdom

Men have little to worry about hormones so why not. Secondly if women stop supplying sex the men will soon start their contraception. Then they will understand one of the many things women have to worry about. As for Habib in UK who thinks contraception is for women, thank God for UK and US who have made mandatory child support - you really won't go around spreading your seed to prove you are a man - take contraception if you do not want to be trapped.
Layla, USA/Nigeria

Just wanted to say a huge THANKS to all the understanding fellas out there who would be willing to give this a go. It's very refreshing to hear that so many men are not the sexists that society sometimes thinks they are! Well done boys.
Sarah, UK

Where can I get it in Nairobi? My heart's thumping with impatience for it! The pill wasn't good for my wife but I believe the opportunity for me to relieve her of the onus is here at last. Fly the drug over soonest possible.
M Munene, Kenya

Sensible men would not go for it immediately
Raimundo L. Santos, Brazil
It's still too soon to predict what might happen with this type of contraceptive. Indeed sensible men would not go for it immediately, as we don't know for sure about the side effects it may cause. Besides, we cannot forget that this stuff is also a drug. I think it's safer to put it into cold storage for a while!
Raimundo L. Santos, Brazil

This will be up there with thinking your guy will remember to put the garbage out and pick up some milk on the way home. Nice if it happens but not to be relied upon.
Louise, Sydney, Australia

I am afraid not! It's of course going to work, but what about the fact that it may lead to even more STDs, as most girls these days are more concerned about pregnancies than STDs. With this contraceptive, there will be no reason to be cautious!
Chukwudi, UK

I think that far from this being the miracle equaliser making men as concerned about pregnancy as a woman on the pill, it will more likely become the wonder drug of the promiscuous male wishing to copulate with as many women as possible without any fear of repercussions.
Pete Smith, UK

And the safety level is? How long did they test thalidomide for? That was safe wasn't it? How long did they use the female pill and on how many women before that was found to have side effects? 55 men for one year does not impress me as a test either for efficiency as a contraceptive or safety and side effects for the user. Would I take it? Not without a lot more testing.
Andrew, London

Bottom line: women get pregnant, not men
Jeff, USA
Bottom line: women get pregnant, not men. One would think that men might take a little more responsibility, but in most cases they don't. Women cannot avoid the consequences. Men of lesser character and morals can.
Jeff, USA

I would say that this is brand new research so that we can chose to say whether it's right or wrong, suitable or unsuitable. However, its acceptance would depend solely on people's perspectives to life, be it connected to cultural or religious outlook.
Raimundo L. Santos, Brazil

No side effects? Long term, I wonder. With all the scares about the pill, HRT and IVF I think it's safe to say that sooner or later certain men who've used this new contraceptive will find that they can't produce sperm when they want to; and that there will be some other unforeseen dangers that no one can appreciate until decades of experience tell us the truth. As a woman I would not want to get involved with a man who had reduced himself to infertile status merely for physical pleasure. But that's the problem - sex is just entertainment now - not something combined with love which leads to babies. No wonder the UK birth rate is down to alarming levels. This drug isn't going to help.
Sara, Belgium

I can't imagine any men complaining about this; for me it will virtually constitute a rebirth. No condoms and not having to worry about the other person's position.
Steve, UK

The sad commentary is that the people who need to use this contraceptive will never see it
TA Guthrie, USA
The sad commentary is that the people who need to use this contraceptive will never see it. And, those who don't will be inundated with information we don't need. The birth rates in the third world demand this attention and they will never receive it.
TA Guthrie, USA

Other than the fact that it needs to go through a few more trials with a much larger sample, I don't know anyone who isn't for it. I think they need to streamline the delivery process but other than that, as a guy, why would you not want control of your ability to impregnate?
Jonathan Rogers, USA

Fantastic idea, so long as there is more research and safety. Contraception is as much the man's duty as it is the woman's. However, as it is the woman who gets pregnant, how many are going to trust a guy that says he has no condoms but "It's alright love, I'm on the pill"? The concerns about increasing STD including HIV should be unfounded. Using a condom is the responsibility of both consenting adults!
Cathy McFerran, Dubai, UAE

I'll stick with condoms... I don't want any hormones mucking around with my body, or my boyfriend's.
Josie, UK

It's time men grew up and took some of the responsibility for their sexual relationships
Nick S, UK
What is it with men that they foresee every attempt to bring about male contraception as an infringement of their male ego! It's time men grew up and took some of the responsibility for their sexual relationships. I had a vasectomy and it hasn't affected me one bit. If the jab had been available then I would have used that until we were sure the vasectomy was the only real answer to permanent unwanted pregnancies that wasn't associated with side effects.
Nick S, UK

I don't suppose we can make this jab a compulsory for pubertal males attending school, can we? A dose at the beginning of the school year and at the necessary intervals in between, for instance. It might do something to cut down teenage pregnancies.
STC, England

It concerns me that the majority of these people are speaking about the contraceptive pill (for both male and female) as if it the only kind of contraceptive available. Surely the most reliable (99%) and safest contraception is the condom, and any other contraception should be taken on top of that - as for male contraception - the more contraception used the better.
Yvonne, UK

It depends, I think if circumstance require is I no I will, but I believe the contraceptive is a woman's thing.
Segun, Nigeira

Once this hits the market, I can see relationships changing for the better. Finally, men have at least half of the reproductive rights that women have!
Joe, US

The only thing that would worry me with this new contraceptive is that people would stop using other forms of protection causing sexually transmitted diseases to spread more easily.
Stewart Grassie, Dundee, Scotland

Of course it should be a joint responsibility
Sally Brooks, UK
I find it amazing that some men will willingly let women take risks with hormonal and other contraceptives, but will not consider it for themselves - too dangerous! Fortunately such things are behind me now since I was sterilised, but I had loads of hassle with all types of contraception in the past. What man would allow a contraceptive implant into his penis which might lead to weeks of bleeding - not many. Yet these are side effects that women are taking every day. Of course it should be a joint responsibility - if not then the only other option is abstinence!
Sally Brooks, UK

I imagine all the men who have commented here about not wishing to mess around with their hormones are perfectly happy for their wives/girlfriends etc to be on the pill.
Helen, UK

Certainly a step in the right direction, anything which can help keep the population in check.
Charles Barnard, USA

How many times have we heard a drug is free of side effects only to find it causes a serious illness after prolonged use. I know that I will not be using it.
Jeremy Cedenio, UK

Just the sight of that needle is contraceptive for me! Seriously, a drug that regresses your body back to puberty doesn't sound comforting ... I'll stick to wearing a condom for a few more years yet - besides, condoms are the most effective barrier against STDs bar not having sex at all.

I will use any and all means of contraception available to me
Damien Tomeric, USA
Barring all of the needless sexist drivel about burdens of responsibility I think that this is an EXCELLENT option. I will use any and all means of contraception available to me until I feel ready to start a family, and it's nice to know that another weapon's been added to the arsenal.
Damien Tomeric, USA

No way. 55 test subjects? Are you crazy? Apart from the potential hormonal side-effects, the last time I checked, this injection didn't stop STDs. Besides, my current girlfriend was conceived while her mother was on the pill, so I am sceptical of the effectiveness of any hormonal treatment. Not to mention the side-effects of female contraceptives. They have side-effects and the odds are not much better than a condom.
Charles, USA

Get the men's "pill" to market fast! If only men could get pregnant, then things like side effects and ability to remember to take it wouldn't be an issue before men start using it commonly and its mass production. Women's contraceptives have side effects, some of which are still unknown (long-term like ovarian cancer), but the consequence of not taking the pill is too immediate and serious for us to worry about mood swings.
Sheven Poole, USA

This really sounds like a great new discovery - one that would help check the World and particularly Africa's ever booming population.
B M Zikapanda, Malawi

If they can prove its safety and effectiveness then I'll be glad to use it. The female "pill" is effective, but even the small chance of unwanted pregnancy is a worry to me. I'd love to have an extra measure of insurance to guarantee that I don't end up a Dad before I want to be.
Tom, USA

Could we at least take turns?
Matt, USA
A lot of male readers seem scared of the possible side effects from the hormones. Yet, we all want worry-free sex, and men expect women to take the pill to prevent pregnancy. That's not very fair. I know the pill causes certain changes in my girlfriend's body that she doesn't enjoy. If this can ease the burden, I'd be happy to help. Could we at least take turns.
Matt, USA

I think it would be a tremendous backup birth control for me if I were in a monogamous relationship. I would never use it as the sole form of birth control though, and would always use barrier protection if I was not in a monogamous relationship. Still the more options available the better.
Bree, USA

A new era of laziness. Wear a condom. The pill is great, but it won't stop HIV.
Sean, US

This is a really great new product - for men. They can finally be sure of not causing any accidental pregnancies. If you're a woman, though, and determined not to get pregnant, you would be a fool to rely on anyone but yourself for contraception.
Wendy, Canada

Working as a medical researcher, I know better than to take anything with less than a decade of study to support it. People are far too quick to take hormones and other "natural" remedies. Let's not forget what estrogen/progesterone did to thousands of women looking for a bit of relief from hot flashes.
John, USA

It's time men took responsibility for their actions too
Andrea, USA
Shan, UK: Your words set women's equality back 50 years! Of course men should share the burden of birth control, especially in a monogamous relationship. For me, my husband is the one who doesn't want more kids, so I say let him be the one to make sure that we don't. Then, I can't be accused of tricking him into getting pregnant again or being careless with contraception so we have a little "accident". No, it's time men took responsibility for their actions too.
Andrea, USA

Contrary to some of your correspondents, there is actually little hard evidence that women frequently lie to their partners about taking the 'Pill' - the evidence is that the 95%+ effectiveness claimed for the Combined oral contraceptive pill actually occurs only in studies conducted by pharmaceutical companies using small numbers of hand-picked paid "volunteers".
"Real life" studies show effectiveness rates of 80-85% that means that out of 100 ordinary women taking the Pill and engaging in regular intercourse, about 15 can expect to become pregnant unexpectedly. It is not a proud record and should be a better known fact amongst our patients. Sadly, there is at present no really safe and fully effective means of contraception other than the word 'No'.
Desmond Persaud, Guyana, S. America

I wouldn't take this treatment in a million years! There is not a single example of hormonal treatment that hasn't led to an increase in cancers. HRT, the pill, tamoxifen - all have potentially disastrous side effects. Anyone publishing results from such a small sample just does not know what they are doing.
Andrew, UK

About time! Relying on my (endearingly dippy) girlfriend to take the pill on time is a worry that I would be happy forgo!
Paul, UK

I'm not putting anything in my body that turns off the system that makes testosterone. That seems really stupid to me.
Lee, USA

I can see it now - "yeah yeah course I'm on the pill!!" Pregnancy's will be on the up once this baby gets on the market
Chris, UK

My concern with the study is that it was conducted on such a little number of people. Also there was no information released with regards to fertility and sperm count of the men after coming off it. Therefore who's to say that when men come off the pill to have children that their sperm count will be as it was before!
Kate, Wales.

I would use it, after it has been around for at least 10-15 years. That is the only way there would be some inclination of possible side effects. One year, and a very tiny test group may show its effectiveness, but not its dangers.
Jez, UK

I'm surprised that so many people think that men wouldn't be trusted to take this
Catherine O, UK
I'm surprised that so many people think that men wouldn't be trusted to take this. Even if it were a pill and not an implant, I think the opposite would be true. Combined with 100% effectiveness, I think we could expect human reproduction to plummet to crisis levels within nine months of this drug being made available.
Catherine O, UK

No side effects? Right! Changing the natural biochemical processes in your body always has effects. The introduction of synthetic hormones can achieve the desired effect, but they always affect secondary reactions and their associated equilibrium states, as the body usually turns off feeder reactions that generated the hormone naturally. This is the male version of a female contraceptive method (chemical sterilisation) that is restricted under UN regulations as it was used in the US (and other countries) for forcible sterilisation of mentally retarded patients. Would I as a man like the ability to turn off my fertility with no, or low, side effects? Yes, of course then I won't get 'surprised' by my girlfriend and the act of having a child would be a joint decision! Would I still use a condom? You bet. I would not be surprised to see a rise in testicular cancer similar to that which we are seeing in breast cancer caused by the use of (certain types of) the pill.
Anon, UK

Yes, I'd use it. There's nothing less fair than bringing an unwanted child into the world, and I'd rather trust myself with preventing this. I have known women to let their broodiness get the better of them and lie about the pill. Never again - men are at last in control!
Russ, UK

To claim 100% effectiveness after only one year of tests with just 55 people is ridiculous. I would want to see clinical trials involving several hundred people over 5 years or so, before I believed in such a high level of effectiveness. I am also concerned at the amount of tinkering with natural processes that seems to be required to ensure that these volunteers had their normal levels of sex drive and energy. How much research is being done into the long-term effects of this approach? One also has to remember that, when contraception fails, the consequences are felt more by the woman than the man. I therefore think it unlikely that women in general would be inclined to rely on the man, unless they could see he was taking precautions. A condom is a visible precaution. Implants and injections aren't.
David Hazel, UK

Thanks but no thanks
Zed Lal, UK
Thalidomide is safe for depression in pregnancy. DDT is a safe insecticide. Beef is safe, BSE does not jump the species gap. Male contraceptive has been deemed 100% effective and shows no side effects. Thanks but no thanks.
Zed Lal, UK

I think it's about time. For so long the responsibility of birth control has weighed heavily on the female and I think that this new found method of contraception is great - but perhaps hundreds of years late. No longer shall the responsibility of avoiding an unwanted pregnancy rely on the woman - couples can now be teams together.
Jessie, Brisbane, Australia

When the female pill came out, was it heralded as a side-effect free form of birth control I wonder? Surely suppressing sperm production will cause other problems in the long run?
Stuart, UK

I've noticed that a lot of the comments written by female people have welcomed this because they have had to shoulder the burden of contraception for decades. Nowadays in schools, we are taught that it is both partners responsibility, and they should talk about it before having sex, which is the correct thing to do in a loving and caring relationship.
Aleks, England

I think it's a fantastic step forward, particularly as the female contraceptive has such side effects for women. However safe sex is about more than preventing pregnancy. If the use of condoms falls dramatically this could lead to a massive rise in the spread of STDs.
Pete W, UK

This is an excellent step towards a world where gender equality is a reality. As long as the treatment undergoes extensive testing and is deemed safe and effective, it should be marketed to the masses! Because both men and women are involved in the act, both should share responsibility in choosing a reliable birth control method to prevent unwanted pregnancies.
Bethany, USA

Give it ten years, and then I might think about using it
Dave, UK
If its only been tested for a year, how do they know there are not going to be any long-term effects? Wasn't there a spate of deformed children born in the 1960's as a result of some ill-tested drug? Give it ten years, and then I might think about using it, once I personally am 100% satisfied that it is safe. I don't trust modern medicine.
Dave, UK

Sadly, some women do an evil thing - duping their partner into thinking she is taking contraceptives, intending to become pregnant without his consent and against his wishes. It is great news that men can take charge of their own fertility, and not becoming fathers when they do not want to.
Andy C, UK

When men start having the babies, maybe they'll take the responsibility for contraception, but until then, I can't see it happening. Women have the incentive of an unwanted pregnancy to make them careful about remembering to use precautions; men don't - it's as simple as that.
Linda, UK

With all we are hearing about a dangerously low fertility rate, it is perhaps not a terribly good idea to go shouting about this from the rooftops. However, I think the NHS should refuse to do vasectomies and offer this contraceptive method to anyone, who would otherwise have had a vasectomy.
Graeme Phillips, Germany, normally UK

It is only possible for a woman to become pregnant around 2 days per month out of her cycle. A man can get a woman pregnant anytime. It's about time that men should take more responsibility over contraception - women have been pumping their bodies full of hormonal chemicals for decades.
Lyn Hudson, HK/ UK

It's a great step forward. This has been almost a "Holy Grail" for many years. Of course I would still advocate the use of condoms for those in casual relationships but, for married couples, this new contraception for men is a most welcome addition to the existing options. Any woman who does not wish to become pregnant would be well advised to make her own arrangements rather than trusting the guy who says, "I'm on the pill" and, likewise, now the man can too make his own arrangements rather than trusting the woman who says, "I'm on the pill".
Kulu, UK

Personally i think it's a good idea. One, its taken as a regular injection so you don't have to worry about anything for a few moths, and apparently it's effective. But the sample of people it was tested on is too small.
Andrew Hansford, UK

You really can't beat a condom, it's far safer!
Malcolm, Channel Islands

This is a typical example of today's society thriving in the western world! It is an absolute disgrace. It is very scary - preventing a possible special gift in a lovely child being born: that's not love at all; that's SELFISH! Think about it - playing with nature will always have present or future side-affects; some very serious!
Anonymous, UK

Anonymous, UK - making sure you only have a child when you are absolutely sure the circumstances are right is called being RESPONSIBLE - it's certainly not selfishness.
Jane, Wales, UK

In reply to anonymous, UK. I am currently 20 years old and I am a full-time student. Why would I want to burden myself with a child when I cannot even support it? What you are saying is that sex should not be for pleasure but for procreation. I'm glad fundamentalist views like that are not taken seriously in today's society.
Peter, UK

Yep, I'd take it. The female pill increases the chances of getting breast cancer, lowers labido etc. So I think this pill would be a safer method.
Dan, UK

No sensible woman should hand over control of her fertility to a man
Shan, UK
The research is too limited. "Replacing" lost testosterone? - be careful guys. But most importantly no sensible woman should hand over control of her fertility to a man. It's women who have to carry the results of birth control - literally. So it's best we sort it out. It's not fair to him either to load it on him. He's just not as sharply motivated as you are, he doesn't carry the result. Don't let unwanted pregnancy, or unwanted abortion, because he was busy and forgot an appointment, wreck a partnership. Get a comfy cap., no chemicals or metal devices, you're in charge and he knows it's there.
Shan, UK

I think this 'sperm suppressant' is no better an idea than the female pill. The pill is 'safe' yet it causes all sorts of side-effects in women from behavioural to short-term physical to long-term physical. I've never expected any woman to take it, always discouraged my girlfriends and now wife from taking it and always preferred condoms as they really are safe and prevent more problems than they cause. As for a male pill - two words: no way. (And in answer to the other question at the top of this page: I don't think my partner would use the new male contraceptive, as she's a woman.)
James, England

Men won't use it and women wouldn't believe us if we did!
Ian Turnbull, USA
"It's Ok, I'm using the new male contraceptive". How many women would be daft enough to believe that line and not take any other precautions? They have the babies, not us. It's a waste of time, money and effort. Men won't use it and women wouldn't believe us if we did!
Ian Turnbull, USA

In response to Ian Turnbull. I do hope that one day you find a partner. Most people in happy stable relationships have this thing called trust. My partner and I are aware of our responsibilites to each other and as such I trust her to remember to take her pill, as I'm sure she would me if this treatment ever became our choice of contraception
Martin, UK

I would absolutely have my partner use the new contraceptive, barring any serious health issues. Too long now, have women carried the burden of responsibility.
Brie Doby, USA

It seems like the solution to contraceptives, irresponsibility and many other problems in our lives, is always some kind of implant. Whether the implant be medical device, computer microchip or radio transmitter, I can just see the human race being a bunch of walking cyborgs in the next century. As the Borg race always said in those Star Trek movies pumped out by Hollywood, "Resistance is futile, prepare to be assimilated." Well I'm ready!
George, United States

It amazes me that people are so willing to stuff themselves full of drugs and hormones
David, UK
It amazes me that people - male or female - are so willing to stuff themselves full of drugs and hormones when there are natural ways of achieving the same ends which are just as effective and completely free of cost or health risk. I guess this is just one more way for the drug companies to exploit them! So - no I wouldn't use it. I've just got too much sense and too much respect for my body (and my wife's).
David, UK

I think many of us would like to know of David's 'natural ways of achieving the same ends which are just as effective and completely free of cost or health risk.' What is this natural male contraceptive? I think male contraceptive injection is a superb idea.
Greg, UK

I'm all for male contraception but until there are more tests done I won't be going near it. If there are any serious side effects I would like to know about them first (wouldn't want body parts falling off). If everything is in the clear then I'd use it without hesitation.
William Teggart, Canada

Male contraceptive? Yes good idea. Good for those who are steady with one partner by marriage or otherwise. But almost certainly if this becomes widespread, an epidemic of sexually transmitted diseases will be round the corner. Guaranteed!
K Riyad, UK

Anyone who thinks that male contraception will stop teenage pregnancy is living in fantasy land
Gerred, UK
Anyone who thinks that male contraception will stop teenage pregnancy is living in fantasy land. How many 15 year old boys are going to be allowed to get this treatment? Rather than force sterilise all men (as a couple of the people on this list suggested) why not make condoms widely available, begin sex education younger, and improve the quality of careers advice in schools? Cheaper, no medical side-effects, and it doesn't violate anyone's human rights.
Gerred, UK

After the finding of the new contraceptive, now the next important step should be to pass a law that every unmarried man and school boy should have this treatment regularly before they can make another girl a single mom. I am sure this would be the solution to one of the greatest poblem (abortion) in human society!
Agha Ata, USA

Agha Ata's comments were astonishingly sexist. Would she support compulsory Deprovera implants for every unmarried woman and girl too? Once the male contraceptive has had more testing (and is available in pill form), I think it will be very useful for men since our current contraception options are condom, abstinence, or vasectomy.
Alexis, UK

Lets hope the cost of using it isn't prohibitive
Ian C, UK

55 men is far too small a sample but, the initial findings make for promising reading. The sample should now be widened and for a longer period ( preferably by several countries). If this too proved positive I would be confident in using it. That said, lets hope the cost of using it isn't prohibitive.
Ian C, Midlands, UK

Contraception is only as reliable as the person using it. I have heard some stupid sound bites today, saying that men aren't responsible enough to take it etc. This is ridiculous. I don't believe that there is anything inherent to a man's memory or gender make-up to make him less reliable than a woman at remembering - if a man is part of a responsible partnership, then he is equally at liberty to use something like this.
Kate , UK

There is no way I'm injecting myself with a female hormone. There is no way I'm also going sterile for months at a time. A pill that kills all sperm within 30 minutes of consumption, which wears off after a day would be acceptable. Injecting hormones? No chance!
Peter, England

It's about time men had to pump themselves full of hormones to prevent pregnancy instead of us!
Jen, UK

It's about time men had to pump themselves full of hormones to prevent pregnancy instead of us! On the serious side, it's a very good thing that there will soon be another contraceptive choice out there. I would 100% trust my husband to take responsibility for contraception, just as he trusts me to take my pill every day. More contraceptive choices is never a bad thing.
Jen, UK

If it is proven to be as reliable and as easy to use as the female equivalent, I certainly would. This means both starting and stopping too. I'm a little concerned about the technique used to start things going again but I'm sure they're make sure it was safe.
Steve G, UK

Until the discovery of this male contraceptive, it has been women who have borne the brunt of our sexual ardour. I have unfortunately been the cause of far too many unwanted, irresponsible abortions. I am pleased to say, in all humbleness, I will not hesitate to enlist as one to receive this treatment.
Professor Georges Didier, Sweden

There is no doubt in my mind that widespread use of this amongst young men would practically eliminate the scenario of the lone, single mum. Men, for the first time ever, would be able to be equally in control of the decision whether or not to get pregnant. And don't tell me that men have always had that with the condom, because most men prefer not to use a condom: that's far too late in the "conception process" for most men, who've other things on their minds by that stage.

If it is proven to be as reliable and as easy to use as the female equivalent, I certainly would. This means both starting and stopping too. I'm a little concerned about the technique used to start things going again but I'm sure they're make sure it was safe.

Until the discovery of this male contraceptive, it has been women who have borne the brunt of our sexual ardour. I have unfortunately been the cause of far too many unwanted, irresponsible abortions. I am pleased to say, in all humbleness, I will not hesitate to enlist as one to receive this treatment.
Professor Georges Didier, Sweden

Yes I would use this new contraceptive - it would take the burden of birth control off my partner and help protect me from the unintended and unwanted ravages of the Child Support Agency too!
Andrew, UK

It's about time
Paul, UK
I would definitely use this. Its about time, men had an alternative contraceptive to the condom, that was down to them to use. It is yet to be seen if the women trust us to use it though!
Paul, UK

About time too ! I will be sending my husband down to the Doc's as soon as it is available. Women have had to bear the brunt of contraception for too long.

I'd like to see more proof of effectiveness and safety than just one study./CPS:QUOTE>

I hate shots (which I gather are designed to counteract the loss of testosterone from the implant) but would use this method. I doubt my partner would change her contraceptive habits, however, and I'd like to see more proof of effectiveness and safety than just one study.
Adam, Scotland

Bravo, it's about time that there was a "pill" for men too. However I doubt that many men will take it and hopefully it will not stop people from using condoms.

The 'snip' has been looming and I'm afraid that I have been rather putting it off. I'd like to know what the 'no side effects really means though'?

I think this will cause a rise in HIV/AIDS
Nicholas Kofi Asamoah, U.K
I think this will increase more unprotected sex as the number of people who only use contraceptives to guard against pregnancy will find a reason not to and as a result cause a rise in HIV/AIDS. I believe condom is the best for me and my partner.
Nicholas Kofi Asamoah, U.K

I think it would be great. However, I would not stop taking my birth control if I could not absolutely trust my partner (thankfully I can). Everyone must be responsible for themselves.
Andrea, USA

At last, something that can allow men control over where and when they reproduce and stop them being at the mercy of women who 'honestly' took the pill.
Gerry, UK

Me personally, no. I'm a female. However, since my husband is the one who doesn't want more children, I'd say it's time he took responsibility for making sure that doesn't happen. I'll be sending him round straight away.

There has not been enough research for me.
Helen W, UK
There has not been enough research for me. It was tested on 55 couples and only for one year. What if this was 5000 couples for several years would the results be so positive? We only found out the problems with the female contraceptive pill after years of research and different versions of it are constantly being released to counter act the problems with other versions.
