Housing and Communities Minister Alex Neil said the Scottish government would commission more research to understand what lay behind all domestic abuse, during the first ever Holyrood debate on violence against men, on 10 June 2010.
Mr Neil said the new helpline, which would support male victims of abuse, would provide intelligence to help form future policy on the issue.
None of the funding for the helpline had come from the £44m allocated to combat violence against women, he said.
The Scottish government launched the dedicated phone line for men in Scotland who suffer from domestic abuse after Scottish police figures showed men made up 14% of victims reporting violent relationships.
Labour's Johann Lamont told the chamber all victims of violence needed support, but it was essential to reaffirm that domestic abuse was rooted in gender inequality and that overwhelmingly victims were women.
Ms Lamont's amendment reflecting that view was passed at decision time, as was the amended motion from Alex Neil.
