Male birth control gel in trials suppresses sperm production effectively

A male birth control gel in early trials showed promise by suppressing sperm production. Developed by the Population Council and NIH, the gel, made of segesterone acetate and testosterone, achieved the desired sperm count of 1 million or fewer per milliliter for effective contraception in 86% of participants by Week 15. This breakthrough could offer men a new contraceptive option in the future.
