Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Melatonin is a potent antioxidant, has been proposed to improve ovarian response and oocyte quality in assisted reproductive technologies (ART). This study evaluated the effects of melatonin supplementation on follicular fluid melatonin levels, hormonal profiles, and reproductive outcomes in women undergoing in vitro fertilization (IVF). Follicular fluid and serum melatonin levels, oocyte quality, embryo development, and pregnancy rates were assessed.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Background: Melatonin, a potent antioxidant, has been proposed to improve ovarian response and oocyte quality in assisted reproductive technologies (ART). This study evaluated the effects of melatonin supplementation on follicular fluid melatonin levels, hormonal profiles, and reproductive outcomes in women undergoing in vitro fertilization (IVF).

Methods: In this double-blind, randomized controlled trial, 80 infertile women were allocated to receive either 5 mg melatonin nightly (n=40) or placebo (n=40) during ovarian stimulation. Follicular fluid and serum melatonin levels, oocyte quality, embryo development, and pregnancy rates were assessed. Statistical analyses included Mann-Whitney U tests for continuous variables and chi-square/Fisher's tests for categorical data.
