How Melatonin May Support Fertility in PCOS

The potential benefits of melatonin for PCOS‑related infertility stem primarily from its ability to reduce oxidative stress within the ovary and to fine‑tune hormonal signaling. Below we explore the key mechanisms.

Reducing Ovarian Oxidative Stress

Oxidative stress events when te production of ROS exceptes thee body 's antioksydant defenses. In PCOS, this imbalance is heightened due to hyperglycemia, hyperinsulinemia, ante te androgenic environment. Te oocyty is especially legable because it contains large compatits of polyunsationate faty acids that are prone tone lipid peroxidation. Melatonin acts ais both a diredirect scavenger of hydroksyl radicals and peroxinitrite and aid indirect antioxicant.

Additionally, melatonin should not t be used during presency unles specifically recommended by a fizycian, as safety data for use after conception is limited.

Long- Term Use

Most fertility-related trials have used d melatonin for 8 to 24 weeks. Long-term daily use (beyond 6 months) has nott been extensively studied in PCOS populations, so it is best to use melatonin only for a definite period aimed at avaluing a treatment goal (e.g., improwiing egg quality before an IVF cycle or recuring ovulation). Periodic breaks or cykling may bee addivable.
