Many couples only begin to have children after several years of being together. But often it is not as easy as planned to put this wish into reality. The examination of sperm is an important piece of the puzzle in the search for the cause. If the desire to have children becomes stronger and nothing happens anyway, the initial laxity gives way to coercion and emotional tensions - the desire to have sex becomes frustration, the fun becomes an obligation. For many women, an odyssey of examinations and therapies begins - everything possible is tried to get pregnant. But sometimes the man is forgotten. And that, although an examination of the sperm is quite simple and often reveals the cause.

Childlessness - first desired, later unintentionally

It is estimated that there are up to 1.5 million couples in Germany with unfulfilled desire for children. Older couples are particularly affected - over the age of 30, the risk of infertility and the likelihood of losing the child during pregnancy increases with women and men. For a younger couple, the probability of getting pregnant without contraception is still 20-30% per cycle, but for women between the ages of 25 and 33 it is only 18% and then continues to fall rapidly. The proportion of unintentionally childless couples in the age group of 35- to 39-year-olds is currently around 15% in the old and - with increasing tendency - 5% in the new federal states.

Reasons for unwanted childlessness are about equally common in both men and women: in 40% of cases, the cause is the male or the female; in about 20%, both show obstacles to pregnancy at the same time.

Causes of sterility

If a couple does not have a pregnancy after a maximum of two years of regular sexual intercourse, they are referred to as infertility or sterility. The reasons are manifold and include in addition to the lifestyle and age (especially the woman) acute and chronic diseases and malformations in men or women. Mental causes can exacerbate the situation, but are rarely the sole cause.

  • In women, inflammation of the fallopian tubes or other organs of the abdomen - often caused by chlamydia - often leads to adhesions and occlusions and thus to infertility. Other common causes include hormonal imbalances and endometriosis, ie accumulation of uterine lining outside the uterus.
  • In men, inflammation z. As deriving spermatic ducts or their closure after mumps, a venereal disease or an injury possible culprits that can lead to transport disorders of sperm cells. Varicose veins of the testes can lead to its overheating and thus to changes in the sperm cells. Other causes include hormonal imbalances and potency disorders. Also discussed are environmental influences that are supposed to cause changes in spermatozoa; especially smoking, too much alcohol and stress are blamed.
