Causes of male infertility

Numerous factors influence male fertility. Here were summarize the most important causes.

Varicose veins in the testes (varicocele)

Varicose veins produce heat, which disrupts sperm production. Even a temperature difference of just 0.5°C can negatively impact the sperm quality. In consultation with your urologist, an operation can be considered in such cases.

Undescended testicles / retractile testes

In this case, the testes remain permanently or intermittently in the groin rather than migrating into the scrotum. In this position, normal body heat can disrupt sperm production. This condition should be corrected surgically as soon as possible in childhood.

Hormonal disorders

If the body produces too few sexual hormones, this can reduce or entirely prevent sperm production. In consultation with your urologist, there are ways to counteract such a hormonal imbalance.

Lifestyle and environmental factors

Nicotine and alcohol can negatively influence sperm quality – as can anabolic steroids, excess caffeine consumption, energy drinks, and certain chemicals (e.g. pesticides). Stress, diabetes mellitus, overweight, and many other factors can also play a role. We would be happy to advise you on these topics.

Infections during adolescence

For example, a case of the mumps during or after puberty can cause irreversible damage to the tissue of the testes.
