Abstract:
Melatonin, a hormone produced by the pineal gland and reproductive tissues, regulates circadian rhythms, antioxidant activity, and fertility. Artificial light at night suppresses melatonin, leading to increased oxidative stress and compromised sperm and egg quality. During assisted reproductive technologies (ART), light exposure generates harmful reactive oxygen species (ROS), impairing gametes and embryos. Melatonin counteracts ROS, enhances antioxidant defenses, and improves embryo development, blastocyst formation, and implantation. This review examines melatonin's protective role in reproduction and how light exposure affects fertility. Understanding these mechanisms could enhance the success of ART and fertility treatments.

Pigmentation
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...
