The new male pill is a hormone-free drug, unlike the female pill. The pill, YCT-529, is a drug called a retinoic acid receptor-alpha inhibitor, which prevents sperm production by blocking access to vitamin A. Experts from YourChoice Therapeutics said that pre-clinical studies showed YCT-529 was “99% effective and 100% reversible with no side effects”. The company said that previous versions of the male pill have attempted to supress the male sex hormone testosterone to prevent sperm production, but this does not stop sperm production completely and has been linked to some complications. Now, 16 British men are testing the hormone-free pill.
