Possible causes of fertility problems
Infertility in a partnership can result from men or women, however, in most cases (70-80%) it is caused by a combination of factors in both partners.
In most cases the causes of infertility are not hereditary but acquired. While in the 1970s approximately 90% of women and men were under the age of 30 at the birth of their first child, today more than one quarter of all couples are older than 30. Female fertility starts to decline at around the age of 30 and then even more sharply after 35 and 40, while the production and quality of a man’s semen slowly starts to deteriorate after the age of 40.
A thorough investigation of the causes in your particular case takes place during the course of diagnostics.
