YCT529 is a drug which acts as a potent and selective antagonist of the vitamin A receptor retinoic acid receptor alpha (RAR-α). In studies on mice it produced a 99% reduction in sperm production, and it has proceeded to early stage human clinical trials as a potential male contraceptive.^[1]

The vitamin A signalling system plays a number of important roles in bodily systems, such as the immune system. “It seems to me inherently unlikely that a compound with such activity would be free of side effects,” says Richard Sharpe, of the University of Edinburgh.^[2]
