Reduced fertility in men is usually the result of a reduction in the quantity or quality of sperm cells. The sperm test is therefore the key to testing male fertility problems. This is a relatively simple test (concentrating in particular on the volume of the sperm sample, the motility of the sperm cells, their number and shape), particularly when compared to the tests for women, which are much more complex. This is also why it is important to detect any problems affecting the man quickly. This can spare the woman unnecessary tests.

Before the sperm test, an extensive interview takes place which includes discussion of all the aspects and events in the person's life which can be important in terms of male fertility (illnesses, surgical procedures, problems during intercourse, etc.). A physical and possibly an ultrasound examination are also conducted of the sex organs (penis, testes, epididymis, prostate, sperm ducts). A blood test can provide information about hormone levels (are enough male hormones being secreted?), about the presence of certain infectious diseases (HIV, hepatitis B and C viruses, syphilis) and about certain abnormalities in the genetic material which can impair male fertility.
