Scientists Discover Molecular Switch That Could Enable Male Birth Control
Researchers at Michigan State University have identified the molecular mechanism that powers sperm's final high-speed sprint, opening a path to the first effective male contraceptive.
Key Takeaways
- Michigan State researchers identified the calcium signaling pathway that triggers sperm hyperactivation for fertilization
- Blocking this molecular switch disables sperm's ability to fertilize without affecting hormones or long-term fertility
- Unlike hormonal approaches, this non-hormonal method could potentially be taken on demand with minimal side effects
