Brief Summary

This randomized, double-blind, placebo-controlled clinical trial investigates the effects of oral Royal Jelly supplementation on sperm DNA fragmentation and pregnancy rates in couples with unexplained infertility. While routine semen analysis appears normal (normozoospermia) in these patients, underlying Sperm DNA Fragmentation (SDF) and oxidative stress are believed to contribute to reproductive failure. Participants will be randomized to receive either 750 mg of lyophilized Royal Jelly or a placebo daily for a period of 3 months (90 days). The study aims to evaluate whether the antioxidant properties of Royal Jelly can improve sperm chromatin integrity, reduce oxidative stress markers, and increase spontaneous pregnancy rates compared to the control group
