NCT ID NCT07740161
First seen Jul 31, 2026 · Last updated Jul 31, 2026
Summary
This trial tests whether a daily supplement called WeNatal For Him can improve markers of male fertility, including sperm quality, testosterone levels, energy, and libido. Forty men aged 30 and older who report low energy and low libido will take three capsules each morning for three months. Researchers will measure changes in sperm parameters and hormone levels, and track participants' self-reported reproductive and sexual health.
