The main causes of male infertility are disorders of spermatogenesis and sperm secretion.
Factors that may impair on male fertility:
- congenital or acquired pathologies of the genitourinary system;
- malignant tumors;
- urogenital infections
- fever of the scrotum (for example, due to varicocele)
- endocrine disorders;
- genetic abnormalities;
- immunological factor.
The main test that starts the study in men is the spermogram.
Specialists of the embryological laboratory evaluate the quantity of ejaculate and its quality: the structure of sperm, their motility.
Men`s test may also include:
- MAR test;
- assessment of hormonal background;
- infectious screening;
- genetic research.
To obtain reliable information, it is necessary to analyze the spermogram twice or even three times. Detection of persistent changes is a prerequisite for referring the patient to a deeper diagnosis and treatment. If there is a risk of progress to deterioration in sperm quality, the patient is advised to cryopreserve their biological material as soon as possible.
