Does soaking in hot springs affect male fertility?

Generally speaking, soaking in hot springs may have a temporary effect on male fertility. The specific analysis is as follows:

When men soak in hot springs, the scrotal area containing the testes is affected by elevated temperatures. Increased temperature may impact sperm production and quality. Research indicates that when testicular temperature exceeds normal body temperature (approximately 37°C), it can lead to reduced sperm production and lower sperm quality. Therefore, prolonged exposure to high temperatures, such as during hot spring bathing, may temporarily reduce sperm count and quality. After soaking in a hot spring, testicular temperature may remain elevated for some time, potentially leading to decreased sperm count and motility. However, this effect is usually temporary; once the body returns to its normal temperature, sperm count and quality gradually recover. Thus, the impact of hot spring bathing on fertility is transient and generally does not cause long-term negative effects on male fertility. Men who are planning to conceive or have concerns about fertility may consider waiting for a period of time after hot spring use to allow their bodies to return to normal temperature, ensuring sperm count and quality have fully recovered.

In addition, if a man has other fertility issues or symptoms of infertility, it is recommended to consult a specialist physician for further evaluation and treatment.
