Summary
Obstructive sleep apnea (OSA) negatively impacts male fertility, significantly reducing sperm motility and vitality. This study highlights OSA as an independent risk factor for impaired semen quality in men.
Area of Science:
- Reproductive Medicine
- Sleep Medicine
- Andrology
Background:
- Obstructive sleep apnea (OSA) is linked to various health issues, including hypertension, diabetes, erectile dysfunction, and reduced androgens.
- The impact of OSA on male semen quality, however, remains under-researched.
Purpose of the Study:
- To investigate the association between obstructive sleep apnea severity and semen quality parameters in men.
- To determine if OSA is an independent risk factor for decreased sperm motility and vitality.
Main Methods:
- 175 male subjects undergoing semen analysis were enrolled.
- Sleep breathing patterns were monitored using a portable device, categorizing participants by apnea-hypopnea index (AHI) severity.
- Statistical analyses, including chi-squared tests and multiple regression, were employed to assess differences and associations.
Main Results:
- Significant differences in progressive sperm motility, total motility, and sperm vitality were observed across OSA severity groups.
- Asthenospermia (progressive motility < 35%) was more prevalent in men with OSA.
- The apnea-hypopnea index showed a significant negative association with progressive motility, total motility, and vitality, even after adjusting for age and BMI.
Conclusions:
- Obstructive sleep apnea is identified as an independent risk factor affecting sperm motility and vitality.
- Further research is warranted to explore therapeutic interventions, such as CPAP, for improving semen quality in patients with OSA.

201
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

01:23Infertility in Males
303
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...

01:13Insufficient Sleep and Sleep Deprivation
187
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.

01:41Spermatogenesis
102.7K
Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male...

01:24Substance Use Disorders Affecting Sleep
201
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
