Disrupted sleep patterns significantly contribute to male infertility, as recent evidence indicates that conditions such as insomnia, obstructive sleep apnea (OSA), and circadian misalignment adversely affect spermatogenesis through hormonal and metabolic pathways. Male infertility accounts for nearly half of all infertility cases, yet sleep disorders remain largely unaddressed in andrology. The emerging data highlights the necessity of integrating sleep assessments into fertility evaluations to identify modifiable risk factors and improve treatment outcomes for affected men.
