Infertility affects millions of couples globally, with male factors contributing up to 50 % of cases. Despite the existing Assisted Reproduction Technologies (ART), decreased sperm quality and male infertility persist. Evidence suggests that sleep is crucial for normal reproductive function, and the noticeable increase in infertility rates aligns with the growing prevalence of sleep deprivation, suggesting a connection between both conditions. This literature review explores the possible links between sleep disturbances, with a special emphasis on insomnia, the most prevalent sleep disorder, and male reproductive health. It delves into the latest findings regarding factors such as sperm quality, hormone levels, and overall reproductive function from studies in mammals, both rodents and humans. Through a concise synthesis of these findings, we unveil potential mechanisms and provide crucial insights for clinicians and researchers in the field of reproductive health.
