Hot water is considered to be therapeutic, especially during cold seasons or when one wants to relax after a long day. Taking a warm shower is, therefore, a common practice.

However, some people may ask, “what is the effect of showering with hot water on sperm?”. This question can be classified under male reproductive health and, specifically, male fertility, as sperms are crucial in the reproduction process.

Sperm production and development undergo several stages, and a change in any stage caused by a particular environmental factor, such as temperature, can affect the quality of the sperm.

How Does Hot Water Affect Sperm?

According to various studies, the testicles, which are responsible for sperm production, have a temperature range of between 34 degrees Celsius and 35 degrees Celsius, which is slightly lower than the body temperature.

The reason for this is that the sperm-producing cells (spermatocytes) are generally sensitive to heat. When they are exposed to temperatures higher than 36 degrees Celsius, which is the normal body temperature, the spermatocytes may fail to function correctly, and this could affect sperm quality significantly.

Hot water showers can increase the temperature of the body. However, the testicles, which are located outside the body, can still maintain a cooler temperature than the rest of the body by regulating the temperature accordingly.

Therefore, in most cases, hot water showers do not directly affect the temperature of the testicles. It is essential to note that taking several hot showers within a short period could affect the regulation mechanism of the testicles, hence leading to changes in the temperature or function of the spermatocytes.

The Effect of Hot Water on Sperm Quality

The quality of sperm is essential factor in male fertility. Sperm quality refers to the concentration, motility, and morphology of the sperms.

Researchers have explored the effect of different water temperatures on sperm quality, and studies have shown that hot water exposure can significantly affect sperm quality, including its concentration, motility, and morphology.

A study published in the Journal of Reproductive Toxicology found that exposing sperm cells to temperatures of 40-45 degrees Celsius can cause changes in the DNA structure of the sperm, affect its movement, and decrease the sperm count.

Another study conducted by researchers at the University of California found that prolonged exposure to hot water temperatures above 45 degrees Celsius can significantly affect sperm motility and concentration.

The Effect of Sperm on Hot Water Quality

It is important to note that hot water can also have an effect on sperm outside the male body. Sperm that comes in contact with hot water die quickly due to the increased temperature.

Therefore, showering with hot water might not have a significant effect on the quality of one’s sperm, but it can lead to a decreased number of sperms in semen and, consequently, reduced chances of conception.

Conclusion

Hot water might not have a direct effect on the temperature of the testicles, but it can affect sperm quality.

Taking hot showers frequently can alter the regulation mechanism of the testicles, causing changes in the spermatocytes’ temperature, thereby affecting sperm quality. Additionally, exposure to temperatures of between 40-45 degrees Celsius can cause changes in the DNA structure of sperm, decrease their count, and affect their mobility.

It is essential to maintain a moderate temperature when showering, particularly when showering for extended periods.
