In the case of an unfulfilled desire to have children, both the man and the woman should always be examined. The man usually consults a doctor of urology or andrology. The cause of fertility problems usually has biological reasons and lies in approximately equal parts with the man and the woman. Often, male infertility only comes to light through a semen sample. After a detailed anamnesis interview, the following fertility examinations take place:

• palpation of testicles, epididymis, prostate and seminal glands
• if required, an ultrasound examination is carried out on the genitalia, prostate and urinary tract
• production of a spermogram
• hormone examinations and genetic tests depending on findings
