A newly found sperm enzyme switch offers a non-hormonal path to male contraception
Scientists have identified a cellular switch called soluble adenylyl cyclase that, when temporarily disabled, stops sperm from swimming without affecting hormones or long-term fertility.
Researchers have developed a promising non-hormonal contraceptive that functions like an on-off switch for sperm motility. By targeting an enzyme called soluble adenylyl cyclase, the drug prevents sperm from maturing and swimming toward an egg. Unlike female birth control pills, this method does not interfere with testosterone or other hormones, significantly reducing the risk of mood-related side effects.
