Male infertility: most common causes


What are the causes of male infertility? This is a question that many men ask themselves when, after carrying out the corresponding studies, they find this diagnosis. Are you looking to have a baby, but there is no way to achieve it? In this article we tell you everything you need to know.

What are the causes of male infertility

Do not think that infertility is already present at birth, as there are times when these setbacks arise at other times in life. Next, we will detail what are the most common causes of male infertility.

Problems associated with sperm

It is necessary that the man has a good number of spermatozoa and that these have the necessary vitality to swim quickly and fertilize the egg. In relation to this, there are two quite frequent inconveniences that are associated with the impossibility of achieving a pregnancy:

  • Azoospermia: No sperm production.
  • Oligospermia: It is characterized by having a low gamete count, which, moreover, are not as healthy as they should be.

Health problems

When health problems are suffered, these can lead to infertility. If the man presents hormonal imbalances, autoimmune pathologies or genetic diseases, such as cystic fibrosis, the chances of not being fertile increase. The same happens if he takes certain medications or if he is undergoing treatment to overcome a serious condition such as cancer.

On the other hand, sperm quality is affected by other complications such as diabetes, severe infections such as gonorrhea or HIV, and enlarged veins in the scrotum (or varicocele). Likewise, he will have difficulty conceiving if he suffers from erectile dysfunction, premature ejaculation, obstructions in the testicles, or lesions in his reproductive organ.


If the man is constantly stressed, smokes, drinks alcohol on a daily basis, or is exposed to chemicals at work, it is likely that he will have difficulty conceiving. All these reasons affect the correct production of sperm and, therefore, are some of the main causes of male infertility.

Spending long hours in the sun or wearing tight pants is also detrimental to semen quality, as your body temperature rises and the force with which gametes travel decreases.

In the same way, we must focus on food when considering the reasons for infertility. Poor or deficient nutrition increases the risk of not achieving fertilization for the woman.

We hope that this information has been useful to you and that you know better what the causes of male infertility are. If you still do not have a diagnosis, but you suspect it due to the lack of pregnancy, do not hesitate to see your doctor.
