Does sauna affect male fertility?

Saunas can affect male fertility if used too often or at too high a temperature. The main reason is that high temperatures in saunas can have a negative impact on the testicles, where sperm is produced, reducing sperm quantity and quality.

Effects of high temperature on testicles

The testicles need to remain at a temperature lower than body temperature (about 35-36 degrees Celsius) for optimal sperm production. When men sauna at high temperatures (usually 70-100 degrees Celsius), the temperature of the scrotum and testicles increases, which can reduce sperm production and development.

Research published in the Journal of Reproductive Sciences shows that frequent exposure to high temperatures in saunas or saunas can reduce sperm production. At the same time, it reduces semen quality in men, especially if exposure is prolonged and frequent.

Reduced sperm count and mobility

Frequent sauna use can reduce the number and mobility of sperm, thereby affecting the ability to fertilize. Sperm must have sufficient quantity and good mobility to meet the egg for successful fertilization.

According to a study published in the Journal of Andrology, men who regularly use saunas may experience a decrease in sperm count and motility. This study shows that high temperatures affect Leydig cells, which are responsible for producing testosterone and nourishing sperm.

Impact on testosterone

High-temperature saunas can also affect testosterone levels, an important hormone for male fertility and physiology.

If the temperature of the testicles increases frequently, Leydig cells can be affected, thereby reducing testosterone production. This not only affects fertility but can also cause decreased sexual desire.

Sperm recovery time

Fortunately, the effects of saunas on sperm are usually not permanent. When men stop or reduce the frequency of sauna use, the temperature of the testicles gradually returns to normal, helping sperm production restore.

Research in the Journal of Fertility and Sterility shows that reducing sauna frequency or avoiding exposure to high temperatures for several months can help improve sperm quality in many men.

Advice for men when taking a sauna

Limit sauna time

Don’t steam for too long. 10-15 minutes at a time is enough to benefit from sauna without increasing testicular temperature too much.

Don’t steam too often

You should only take a steam bath 1-2 times a week to avoid affecting testicle temperature.

Avoid taking a sauna right before you plan to have a baby

For men planning to have children in the near future, avoiding exposure to high temperatures from saunas can help improve sperm quality.
