First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests a new daily pill called YCT-529 for male contraception. It involves 88 healthy men who have decided not to have children. The pill is taken for 28, 90, or 180 days to check its safety, side effects, and how well it works. This is an early step toward giving men a daily birth control option.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
YCT-529 (a daily oral pill for male contraception)
What this could lead to
If successful, this could lead to a new, non-hormonal daily birth control pill for men, giving couples more options.
What could go wrong
This is an early-phase trial with only 88 men, so it may not prove safe or effective enough. Side effects or lack of reliable contraception are possible risks.
