Summary

This study tests whether taking melatonin for 4 weeks before egg retrieval can improve egg quality and pregnancy rates in women with diminished ovarian reserve (low egg supply). The trial involves 64 women undergoing ICSI (a type of IVF). Half receive melatonin, half a placebo, and researchers compare pregnancy success rates.
