A medical condition in which men is not able to produce offspring due to no sperm count in semen. It is linked with infertility. Azoospermia affected almost 1% of the male population. The only symptom of azoospermia is the disability to get the partner pregnant. It can be categorized into two types;
Obstructive azoospermia: A person produces normal sperm but there is a blockage in the reproductive tract of testicles. That means no significant sperm can go into the semen.
Non-obstructive azoospermia: It is associated with the production of poor sperm. In this condition no sperm in the discharge due to loss of spermatogenesis (the production of mature spermatozoa).
Causes of obstructive azoospermia:
- Vasectomy is the most common cause of obstructive azoospermia. It’s a surgical method for male contraception in which sperm absorbed by the body.
- Infection of testicle is also the reason behind obstructive azoospermia. Because of the infection the blocked tubes unable to transmit sperm through the ejaculatory duct.
- The cyst could also cause hindrance in the ejaculatory duct to pass sperm.
Causes of non-obstructive azoospermia:
- It is due to the abnormality of testicles.
- Another reason of non-obstructive azoospermia is the poor performance of hormones that regulate sperm production.
- The removal of some genes on a certain chromosome can also cause non-obstructive azoospermia.
