Temperature and Male Fertility

Temperature and Male Fertility

Read below to find out how temperature may impact sperm and male fertility, and tips to keep yourself cool

Why are your testicles located outside the body? They’re designed that way to keep sperm cooler, slightly lower than your core body temperature. This system generally works well, but some environmental factors may keep the testicles from keeping as cool as they need to.

For example, some workplaces are hot, like workshops and busy kitchens. If you work in this type of environment, you may find it difficult to cool off. This means that your sperm may not be kept at an ideal temperature. If possible, take regular breaks to go outside and cool off when you work in a heated environment.

Office workers aren’t immune to the potentially damaging effects of temperature. Sitting in one position for too long can cause the testicles to overheat. Try to get up and walk around at least once an hour to improve blood flow and cool down. Be mindful of laptop use, too. Some laptops can get very warm, and if you’re sitting with a laptop directly on your lap, you could be raising the temperature of your testicles.

The Good News

Your body is constantly making new sperm to replace old ones that have died or were released during ejaculation. Exposure to higher-than-normal temperatures may damage the sperm that are already formed, but once an optimal temperature is restored, new sperm can develop normally. This means you don’t have to give up that hot tub forever, just avoid it while you’re trying to conceive.

Consider Your Clothing Carefully

Tight undergarments, like undergarments made of nylon or other less-breathable fabrics, may contribute to overheating. Get into the habit of wearing cotton boxers or other loose-fitting clothing so your body’s natural cooling and circulation can work as well as possible.

Avoid Long Soaks in Hot Baths

A long soak in a hot tub or hot bath may be relaxing, but it isn’t the best thing for sperm production. Prolonged exposure to the high temperatures in a sauna can decrease sperm count or sperm quality. If you’re planning on trying to conceive in the near future, stay away from hot water and opt for a refreshing shower instead.
