Cell Phones

This one sounds a little crazy, but yes, believe it or not, if your guy leaves his cell phone in his pocket, he could very well be damaging his sperm quality. Studies have found that when semen is exposed to the radio waves that are emitted by cell phones, it can cause damage to the quality of the sperm.

There was a study done in 2008 that noted that men who spent the most time on a cell phone had the worst sperm counts and quality, but most doctors agree that as long as your man doesn’t keep his cell phone in his front pocket, he should be okay.


Anything that causes overheating of the testicles can damage the sperm. There are many things that could cause the testicles to overheat, including hot baths, hot tubs, and saunas. Also, tight clothing like bicycle clothing and tight briefs could cause the testicles to overheat. Men who sit with their laptops on their lap very often might also damage their sperm due to the heat from the computer.

Radiation Exposure

Men who are exposed to high levels of radiation can also damage their sperm. While this doesn’t usually apply to men who only have the occasional x-ray, men who are exposed to very high levels of radiation, as with cancer treatments, might permanently damage their sperm.


When a man is sick for a long period of time, it can also damage his sperm if he has had a recent illness. A high fever can actually have the same effect on sperm as heat damage from saunas or hot tubs. If your man has been sick within the past few months, it could possibly temporarily damage his sperm.

Too Much/Too Little Testosterone

Too much testosterone in the body can be a problem for sperm. Many men take testosterone supplements to enhance libido, build muscle, etc, but it can also damage sperm. Too much testosterone can actually shut down the pituitary gland, which controls sperm production. On the contrary, if a man has too little testosterone in his body, that can also hinder production of sperm as well. Testosterone is a very fine balancing act, and having too much or too little can hurt sperm count.


Obesity is one of the most common causes of problems with sperm. Obese men who are otherwise fertile have significantly lower sperm counts than men who are a healthy weight. Keep this in mind, since obesity in women is known to lower fertility as well.

Drug Use

If a man smokes marijuana or uses other illegal drugs, he should know that his sperm levels might be compromised. The THC in marijuana can cause sperm counts to fall. There are other negative effects of using drugs as well, of course, and sperm health should just be one reason to stay aperm, and way from them.

Bad Diet

This one is sort of linked to obesity, but not always. The body needs certain vitamins and nutrients in order to produce healthy sperm. If a man only eats junk food and unhealthy stuff, his body won’t be able to make healthy sperm. Eating a healthy and well balanced diet is key to healthy fertility.

Alcohol Use

Men who drink large amounts of alcohol can do serious damage to their fertility. Men who drink more than four drinks per day can lower their sperm counts severely. Plus, since alcohol damages the liver, men who drink a lot can have higher levels of estrogen, which in turn will stop sperm from being produced.


Smoking has so many different bad effects, and the bad effects on sperm are just one of them. The toxins in tobacco cause the sperm to swim very slowly, and can damage the makeup of the sperm as well. There have even been studies that show that if a woman smokes during early pregnancy, it can damage her SON’S sperm later in life.
