Saunas and Male Fertility: Do Saunas Really Kill Sperm? Exploring the Truth

The use of saunas as a form of relaxation and physical therapy has been around for centuries. However, in recent years, concerns have been raised about the impact of saunas on male fertility. The belief is that the heat from the sauna could kill sperm and reduce male fertility. But is there any truth to these claims?

Studies have shown that there is some truth to the effect of saunas on male fertility. High temperatures in the testicular area can cause damage to the sperm-producing cells and reduce sperm count. However, the level of heat required to cause such damage is much higher than what is typically experienced in a sauna.

There are also conflicting opinions on the effects of sauna heat on male fertility. Some studies have suggested that there is no significant impact on sperm quality or concentration, while others have warned against prolonged exposure to high temperatures.

So what does the scientific evidence say? In this article, we will explore the truth about the effect of saunas on male fertility and assess whether there is cause for concern.

Myths and Misconceptions

There are many myths and misconceptions regarding saunas and male fertility. One of the most common myths is that saunas kill sperm. While it is true that high temperatures can have a negative impact on sperm production and quality, saunas do not necessarily kill sperm.

Another misconception is that frequent sauna use can lead to permanent fertility problems. While prolonged exposure to high temperatures can have a negative impact on sperm production, it is usually a temporary issue that can be reversed with time.

Some people also believe that the type of sauna matters when it comes to male fertility. For example, they may think that traditional Finnish saunas are less harmful than infrared saunas. However, there is no evidence to support this claim.

Finally, some people believe that sauna use can improve male fertility. While there is some evidence to suggest that moderate sauna use can have other health benefits, such as improving cardiovascular health, there is no evidence to suggest that it can boost male fertility.

Exploring the Truth

Despite the long-held belief that saunas can kill sperm and decrease male fertility, the truth is somewhat more nuanced. While it is generally accepted that high temperatures can negatively impact sperm count and quality, the actual effects of saunas on male fertility vary depending on a number of factors.

First and foremost, it’s important to note that not all saunas are created equal. Traditional Finnish saunas, for example, typically operate at much hotter temperatures than infrared or steam-room saunas, which can have different effects on sperm health.

Additionally, there is no one-size-fits-all answer when it comes to how saunas will affect an individual’s fertility. Factors such as age, overall health, and current sperm count can all play a role in determining how much of an impact a sauna session will have.

Ultimately, more research is needed to fully understand the effects of saunas on male fertility. While it is clear that high temperatures can be detrimental to sperm health, the specific impact of saunas on fertility is still a matter of debate in the medical community.


In conclusion, it is safe to say that sauna use does not kill sperm. However, it should be noted that prolonged exposure to high temperatures can have a negative impact on male fertility.

It is important for men to take precautions when using saunas, such as limiting the amount of time spent in the sauna and avoiding saunas altogether if they are trying to conceive a child. Additionally, taking breaks between sauna sessions and staying hydrated can help to mitigate any negative effects on sperm count and motility.
