Two Kenyan boys who had their penises cut off to make a potion to treat HIV/Aids have had reconstructive surgery in Spain.
The boys were flown to Spain at the end of January
The youngsters, aged 12 and 14, were mutilated after reportedly being given drugged food or drink by strangers.
Surgeons in Valencia said both were making an excellent recovery and the eldest was due to have a testicular prosthesis implanted next week.
The functional organs were rebuilt with forearm tissue and bone segments.
"They had attacked them to cut off their penises to sell ... for making a type of potion which according to a local belief cures Aids," said Dr Pedro Cavadas, from the Levante Rehabilitation Centre.
Dr Cavadas, who runs a humanitarian mission in western Kenya carrying out all kinds of reconstructive surgery, flew the boys over from the Bungoma region at the end of January.
Dr Cavadas told the BBC news website that the boys' penises will be fully functional and recover complete feeling.
"They will be able to have normal sexual relations with erogenous sensitivity," he said.
The 14-year-old lost an ear, which was also rebuilt, trying to fend off his attackers after regaining consciousness during the mutilation, said Dr Cavadas.
"It seems that the dose of medication that they gave him to knock him out ... was badly calculated, and so he woke up in the middle of the attack," he said.
"He then tried to defend himself and because of this has a lot more injuries."
The foundation's website said two people had been arrested in connection with penis mutilation, although it was not clear if they were linked to the attacks on the boys.
"The practice of mutilating the penises of virgin boys is not a tradition among Kenyan tribes.
"The object of this mutilation was to make a potion to cure HIV/Aids," the website said.
Dr Cavadas, who noted this type of attack was rare in Kenya, said the boys had been transformed by their surgery, which took place at the end of January.
"They are fantastic, happy, their faces have changed and their lives have changed. They don't have to use a catheter...and they can live like children, messing around and being naughty."
