Male birth control drug 100% effective in mice, study shows. What about humans? – National | 24CA News

An experimental new drug that briefly blocks the male sperm is being hailed as a “game changer” within the seek for an elusive contraception capsule for males.

“So the idea is they take that pill about 30 minutes before they want to have intercourse and then their fertility is protected and then about 24 to 48 hours, their fertility comes back,” Dr. Melanie Balbach, a copy biologist at Weill Cornell Medicine and co-author of the examine, instructed Global News.

Women on contraception capsules usually should comply with an everyday multi-week routine to stop ovulation.

In the case of this drug being designed by Balbach and her colleagues, “it really hopefully can be taken as often as the men want to have intercourse,” she mentioned.

However, it’d take two to a few years earlier than they’ll begin scientific trials and see if the drug is protected and efficient for people, she mentioned.

“We hope in about six to eight years, if everything goes well, it will come to (the) market.”
