Male Birth Control Pill Passes Human Safety Test
Scientists are working on a new birth control pill for men that doesn't use hormones.
This new pill, called YCT-529, was tested on a small group of men who had already had vasectomies to make sure it was safe.
The pill works by stopping sperm from being made.
The first tests showed that the pill was safe for the men who took it.
Researchers are now doing more tests to see how well it works and the best amount to take.
This could give men another way to control if they have children, and it could be a safer alternative to some of the other methods of birth control.
A hormone-free male birth control pill, YCT-529, passed its first human safety test.
The pill blocks a vitamin A metabolite in the testes, preventing sperm production without affecting hormones.
The phase 1 trial involved 16 vasectomized men; no serious adverse events were reported.
Researchers are determining the optimal dosage, with further trials underway.
The pill offers a safe, reversible, and non-hormonal alternative to existing male birth control.
