Clarifications for him

Unfruchtbarkeit des Mannes kann eine Ursache dafür sein, dass sich keine Schwangerschaft einstellt. The spermiogram is therefore an important screening test for determining a man's fertility.

Possible causes of pregnancy failure in men

Problems with semen quality are the main cause of reduced male fertility. This means:

  • too few sperm
  • Insufficiently motile sperm
  • malformed sperm or a combination of these factors

In general, smoking and stress as well as being overweight or underweight have an unfavorable effect on sperm quality. Age also plays a role for men. From the age of 40 – 45, fertility can decline and with it the chances of success of fertility treatment.

It is important to us that you can understand what is happening in your body and why we are suggesting which therapy to you.
