Causes Of Male Factor Infertility

Common causes of male factor infertility include cigarette or marijuana smoke, heavy alcohol consumption, prescription drugs, obesity, infections, exposure to toxins, overheating the testicles, infectious diseases such as mumps after puberty, cancer treatment, hernia repair, undescended testicles, etc. It has also been established that undertaking certain activities as driving and cycling over long distances, especially on a hard and/or overheated seat, negatively impact male fertility. Genetics can also be a factor. These causes could be classified thus:

Sperm Disorders

This is indicated by sperm being produced in abnormally low numbers (oligospermia), not being produced at all (azoospermia), if the majority of the sperm produced are shaped abnormally, or if they are not able to move well, thus making it almost difficult to reach, or penetrate the egg for fertilization. Common causes of sperm disorders could be genetic defects, infections, hormonal imbalance, radiation exposure, or any other testicular trauma.

Physiological Problems

Common causes of such physiological problems include scar tissue from prior surgery, or from a pathway infection. Also, the presence of varicose veins in the testes could also interfere with sperm production. A good number of such problems are congenital.

Immune System Disorders

This occurs when some men develop antibodies to their own sperm, attacking and weakening the sperm. These antibodies could also attach to the sperm, preventing their ability to fertilize the egg.
