10 common ways Men damage their Sperm without knowing

Sperms are very fragile and there are a few common habits we do that can kill them. The goal of most if not all marriages is to have children, and live happily ever after. Children brings so much joy to father, mother, friends and relatives alike. To make this possible, Mr. sperm has to meet Mrs. Egg and come together to form the baby. When this cannot happen, we say that there is infertility.

Infertility is a very serious challenge in many homes, and has caused separation in a number of families. Infertility can be caused by a number of factors either from the man, or from the woman. You can read more on this here.

In this write up, I would like to share with you a few ways that you might be damaging your sperms or its production without even knowing it. They include;

  1. Tight underwear
  2. Hot baths
  3. Infections
  4. Varicoceles
  5. Laptops
  6. Drugs
  7. Mobile phones
  8. Smoking
  9. Marijuana
  10. Steroids

Tight Underwear

Putting on very tight pants and underwear can increase the temperature in the scrotal area, and this is not healthy for your sperms. It may kill already produced sperm & reduces your body’s production of sperm. To prevent this, you should start the practice of using loose under wear instead of tight pants. No wonder in the pasts, our parents were used to tying wrappers and they hardly had this issues.
Ladies, ensure your man goes to bed naked if you want him to become a father.

As explained before, Wearing tight underwear like pants or shorts keep your testicles closer to the body, leading to warmer temperatures that may kill sperm & lower sperm count.

Hot baths

most people love a hot water bathe, but why it is fun and enjoyable, it is not health for your little guys down there. Hot water baths also exposes the body to heat, which is not good for the production of sperm & frequently doing this may cause low sperm count. Same thing with men who often use saunas. It is advisable to have a cold or warm water bathe.


Infections are always a concern wherever you find them, causing all kinds of health problems for both men & women. Some Infections have been known to affect the production or storage of sperm. These Infections of the genital organs e.g. mumps, orchitis, epididymitis etc, block sperm production or passage in the Vas. This can be caused by untreated & longstanding gonorrhea, leading to permanent damage to the testis & hence infertility.


Varicoceles simply means the swelling of the veins that takes blood away from the testis. It is a common cause of low sperm count & infertility in men in our environment, and it is mostly ignored.
Sperm cells are very fragile. Accumulation of blood in an area causes increased temperature in that area. When this happen in varicoceles, the raise in temperature inside the testis may kill the sperm or reduce sperm quality. Make an appointment with your urologist today for check up & to treat your varicoceles.


Although it is rightly called a laptop, does not mean that we should always use them on our laps. The amount of heat generated by a laptop in use, is very much and when you constantly place this amount of heat on your laps, it may disrupt Sperm production & cause irreversible changes in your male reproductive function. Practice the habit of using your laptop on a table instead.


Drugs/Medications: Some common legal & illegal drugs can affect sperm production. Examples of these include;

  • drugs for management of Hypertension (high blood pressure), e.g; Atenolol
  • NSAIDs for pain like Sulfasalazine
  • drugs for Cancer affects all rapidly growing cells like sperm cells, blood cells, etc.
  • Others are cocaine, & many herbal medications.

See a doctor before taking any drugs.

Mobile phones

There have been suggestions & evidences of recent that the heat & radiation from our mobile phones can be enough to cause damage to the sperm. Hence, it is best to keep the mobile phones as far away from the testes as possible. Rather than put your phones in your front pocket as is commonly done, you can practice holding it in your hands or putting it in your back pocket.


just like alcohol, smoking can cause damage to the sperm & lead to low sperm account. It can also cause problems with erections. Smoking has been suspected to reduce the sperm ability to swim actively to fertilize a woman’s egg. Quit smoking today if you have challenges of infertility.


Regular consumption of marijuana in any form (whether cooked, smoked, snorted, etc) can cause reduce your sperm count. This is because marijuana reduces the amount of testosterone in the body. Testosterone is a hormone found in the body of a man that makes him a man. It is needed by the testis to produce sperm.


Steroid is a commonly abused medication today, especially by body builders who want to improve their muscles as well as by drug addicts. This steroids when abused can affect the production of sperm by affecting testosterone production. This leads to a decreased sperm production & hence, low sperm count.
Stop steroid abuse today.
