Can Sleep Apnea Cause Poor Sperm Health?

Male fertility is a complex process influenced by various factors, and recent research suggests sleep apnea may be one of them. Sleep apnea, particularly obstructive sleep apnea (OSA), is a sleep disorder characterized by repeated breathing pauses and reductions in oxygen levels. While its connection to snoring and daytime sleepiness is well-established, the impact of OSA on sperm health is an emerging area of investigation. This article explores the potential link between OSA and sperm quality, drawing insights from recent studies.

Sleep Apnea and Male Fertility

A 2021 study published in “Pulmonary Medicine” investigated the association between OSA and male infertility in a large Taiwanese population. The research, involving over 4600 men with infertility and a control group, found that OSA was an independent risk factor for infertility. Men with diagnosed OSA were 1.24 times more likely to experience infertility compared to those without the condition. Interestingly, the study also suggested a correlation between the duration of untreated OSA and infertility risk.

Another study, published in “Sleep Breathing Physiology and Disorders” in 2023, focused specifically on the impact of OSA on semen quality. Researchers evaluated sperm motility and vitality in men seeking infertility treatment. They categorized participants based on the severity of their OSA, as measured by the Apnea-Hypopnea Index (AHI). The results revealed a significant decline in progressive motility, total motility, and sperm vitality with increasing AHI. The study also found a higher prevalence of asthenospermia (reduced sperm motility) in men with OSA.

The Mechanism

While the studies mentioned above highlight a potential link, the exact mechanisms by which OSA might affect sperm health remain under investigation. Several theories attempt to explain this connection:

Oxidative Stress: Sleep apnea episodes cause fluctuations in oxygen levels, potentially leading to increased oxidative stress in the body. This oxidative stress can damage sperm cells and hinder their motility and function.
Hormonal Imbalance: OSA may disrupt hormone production, particularly testosterone, which plays a crucial role in sperm production and function. Studies suggest a potential link between OSA severity and lower testosterone levels.
Inflammation: Chronic inflammation is associated with OSA and may negatively impact sperm production and maturation.

Sleep Apnea Treatment and Fertility

The good news is that OSA is a treatable condition. The most common therapy for OSA is Continuous Positive Airway Pressure (CPAP) therapy, which involves wearing a mask during sleep that delivers a constant stream of air pressure to keep the airways open.

The 2021 Taiwanese study mentioned earlier hinted at a potential benefit of OSA treatment for male fertility. Men with OSA who received treatment (CPAP or surgery) did not show the same increased risk of infertility as those who remained untreated. Further research is needed to confirm this link, but it suggests that addressing OSA might improve sperm health in some cases.


What’s the Verdict?

The research exploring the connection between OSA and sperm health is still in its early stages. While the studies discussed above offer compelling evidence for a potential association, more research is needed to fully understand the mechanisms involved and the long-term implications for male fertility. Future studies might investigate:

  • The impact of different OSA treatment options on sperm quality.
  • Whether the duration of untreated OSA affects the reversibility of sperm damage.
  • The effectiveness of combined treatment approaches for both OSA and male infertility.


Sleep apnea is a prevalent sleep disorder with potential consequences for male fertility. While the exact mechanisms remain under investigation, recent studies suggest a link between OSA and decreased sperm motility and vitality. Fortunately, OSA is a treatable condition, and managing OSA may potentially improve sperm health and fertility outcomes. Men experiencing both sleep apnea and infertility concerns should consult with a healthcare professional to discuss treatment options and explore the potential impact on their fertility.

If you’re concerned about sleep apnea or suspect you might have it, talking to your doctor is crucial. Early diagnosis and treatment of OSA can significantly improve your sleep quality and overall health. Additionally, addressing underlying health issues like OSA can be a positive step towards a successful fertility journey.
