Male birth control pill passes first test

摘要

CHICAGO - In a small study, a once-daily capsule safely suppressed reproductive hormones in men, making it an appealing candidate for a male birth control pill. After about a month, a prototype pill called dimethandrolone undecanoate, or DMAU, had reduced levels of hormones that are necessary for sperm production. None of the 83 men who completed the treatment suffered troubling symptoms, such as a loss in sexual function, that can arise with a dramatic drop in testosterone, researchers reported March 18 at the Endocrine Society's annual meeting.
