Male fertility can be affected by three factors:
- Pretesticular factor
- refers to problems in the endocrine system. The signals sent by the brain are essential for sperm production. For this reason, if there is any error in communication, sperm will not be produced. Diseases that cause male infertility due to this factor are hyperprolactinemia, hypogonadism, thyroid problems and diabetes.
- Testicular factor
- all defects that affect the testicles themselves. Some possible causes of testicular factor are Noonan syndrome, Klinefelter syndrome, cryptorchidism, etc.
- Post testicular factor
- includes all aspects that affect the spermatozoa themselves once they have already formed in the testicle.
- Sperm factor
- is the main cause of male infertility and is due to defects in the sperm.
