Infertility is a common problem and in approximately 50% of all cases this is related to the male partner. There are many reasons for impaired male fertility and deterioration in semen quality ranging from congenital diseases, hormonal imbalances, operations in the groin, scrotum or the pelvic area up to inflammatory changes in the prostate or a dilated, varicose vein (varicocele) in the scrotum affecting testicular function. Primary infertility describes couples who have not been able to conceive a child after having regular unprotected sexual intercourse with each other for 1 year and who, prior to this attempt to conceive, have never been able to conceive. Secondary infertility describes couples who have not been able to conceive a child after having regular unprotected sexual intercourse with each other for 1 year, but who have already conceived (and either carried the pregnancy to term or had a miscarriage). The chances of successfully conceiving with secondary infertility are usually better than with primary infertility.
In case of infertility both partners should be tested – not just the woman. The test itself is painless; semen analysis provides the most important results.
