A new study suggests that lack of oxygen, caused by high-altitude hiking and conditions such as sleep apnea, may be a contributing factor. male fertility Celebrated in the last 50 years. Published in Nature Reviews Urology, the review highlights how “testicular hypoxia” – Lack of oxygen in the testicles – can negatively impact sperm quality and overall reproductive health.

Infertility in men is defined as the inability to achieve pregnancy after 12 months of regular, unprotected intercourse, while subfertility refers to a reduced chance of conception. Lead author Dr. According to Tessa Lord, a reproductive biologist and senior lecturer at the University of Newcastle, Australia, testicular hypoxia is a significant factor in the decline in male fertility. Chronic medical conditions such as sleep apnea and varicocele (enlarged veins in the scrotum) are primary contributors to this condition.

Dr. “Varicocele is a common abnormality that accounts for infertility in up to 45% of men struggling to conceive,” Lord explained. Sleep apnea, another condition associated with testicular hypoxia, occurs when throat muscles narrow the airway during sleep, causing low blood oxygen levels. Rising rates of obesity, a major risk factor for sleep apnea, have exacerbated the issue.

Exposure to high altitude, where oxygen levels are significantly lower, is also linked to a temporary decline in fertility. While hiking in these areas may cause short-term testicular hypoxia, the effects may take months to resolve after returning to sea level. Dr. Lord stressed that although short-term exposure to hypoxia can affect sperm count and quality, the long-term implications for fetal development and the health of offspring are unclear.

This study underlines the importance of addressing testicular hypoxia as a factor in male infertility, given the significant decline in sperm counts in recent decades. “Emerging evidence suggests that testicular hypoxia in fathers can lead to developmental issues in the fetus, potentially resulting in fertility problems in the next generation,” Dr. Lord said.

Ways to Boost Sperm Count Naturally After High Altitude Exposure

If you have recently returned from a high-altitude environment or are dealing with other oxygen-deprived conditions, there are natural steps you can take to improve sperm count and quality:

Maintain a balanced diet: Include foods rich in antioxidants, such as fruits, vegetables and nuts. Zinc-rich foods like pumpkin seeds and oysters, along with folate-rich greens, support sperm production.

Exercise regularly: Moderate physical activity improves blood circulation, important for healthy sperm production. Avoid excessive exercise, which can increase oxidative stress.

Stay hydrated: Adequate water intake ensures optimal blood flow to the reproductive organs to promote sperm health.

Get quality sleep: Address sleep apnea with medical interventions such as CPAP devices or lifestyle changes to improve oxygen levels and reduce testicular hypoxia.

Avoid smoking and alcohol: These habits can increase oxidative stress and reduce sperm quality.

Manage stress: High stress levels can disrupt hormone production and affect fertility. Practices like yoga and meditation can help.

Consider supplements: Supplements containing vitamin C, vitamin D, and coenzyme Q10 have been shown to improve sperm health.

Stay cool: Avoid exposure to extreme heat, such as hot tubs or saunas, which can negatively affect sperm production.
