Oligozoospermia is the presence of an abnormally low number of spermatozoa in the ejaculate.
Patients with oligozoospermia, especially in cases of severe oligozoospermia, may progress to a diagnosis of cryptozoospermia and subsequently to azoospermia, i.e., absence of sperm in the ejaculate.
The diagnosis of oligozoospermia must be associated with tests to evaluate the origin of this oligozoospermia and to be able to anticipate its evolution. In this way, an early diagnosis makes it possible to establish an adequate treatment (hormonal, antioxidants, etc.). Likewise, patients with moderate or severe oligozoospermia are usually recommended to cryopreserve a semen sample in order to foresee a possible absence or decrease in sperm quality.
