Sperm are sensitive to high temperatures. Sperm cells tend to die when exposed to too much heat. Continuous exposure to higher temperatures can cause sperm production to be lower, or cause the production of abnormally shaped sperm cells resulting in male infertility. Testicles are located outside of the human body because the ideal temperature for sperm production, and thus for male fertility, is about three to four degrees below the ideal human body temperature.
Overheating can be due to reasons that are internal such as in the case of a high fever. It can be also due to factors that are environmental or physiological. Activities such as cooking, grilling, motorcycling, sauna, and cycling can cause heat production. Using laptops and cellphones for long durations can also result in overheating. Physiological factors include Varicocele (enlargement of the veins within the loose bag of skin that holds your testicles), late descended testicles and obesity.
To promote male fertility and healthy sperm, avoid these 5 hot situations;
Avoid spending prolonged periods of time in hot tubs and/or Jacuzzis.
Sitting and soaking in hot water will raise the body temperature, which can have a negative effect on male fertility.
Don’t wear tight-fitting pants or underwear.
When you wear tight jeans, pants or briefs, you’re putting your scrotum in a tight environment that can trap heat in the testicles, and especially during the hot months when you may already be overheated. Wear boxers or loose pants made from natural fiber like cotton.
Do not sit for long periods of time without getting up.
Sitting, whether for work, for long driving trips, or just to watch television, can also trap heat around the scrotum, which is not beneficial for male fertility. Take breaks to stand and walk around.
Avoid prolonged bike rides, especially in the heat.
Tight biking shorts, combined with long periods of sitting on a bike seat, may cause friction and pressure on the testicles. This can cause the testicles to become overheated, too. Men should wear loose shorts and take shorter bike rides or take breaks during longer rides.
Don’t put a laptop computer directly on your lap for long periods of time.
The battery on laptop computers can produce quite a bit of heat. It’s best to place your laptop on a desk or table instead of on your lap.
