The term infertility refers to the inability to conceive after one year of contraceptive-free intercourse. If pregnancy does not occur within a year among those younger than 35, or after 6 months among those older than 35, it is recommended to seek help from a reproductive medicine specialist.
Male factors contribute to 40% of all infertility cases. Semen analysis is the basic examination of male fertility. If semen analysis shows fundamental deviations from normal levels an examination by an andrologist is indicated. The diagnosis of male infertility focuses on more frequent disorders, such as testicular and epididymal abnormalities, varicocele, or abnormalities of the prostate gland and vesiculae seminales. An examination of the partner is necessary even if the male examination shows abnormal results.
