A Clinical Trial to Evaluate the Effects of a Supplement on Markers of Male Fertility
This study will evaluate the effects of the WeNatal For Him supplement on markers of male fertility over a 3-month period. The trial is a single-arm, unblinded study enrolling 40 male participants who will take 3 capsules of the test product daily in the morning with their first meal. Participants will complete questionnaires at Baseline, Month 1, Month 2, and Month 3. Semen analysis will be conducted at home at Baseline and Month 3, and blood testing will be performed at a local Labcorp location at Baseline and Month 3. The primary focus is on sperm quality parameters and testosterone levels, while secondary endpoints capture participants' perceptions of changes in reproductive and sexual health, including energy and libido.
