To determine whether obstructive or non-obstructive azoospermia is present, it can be examined through a physical examination or through a testicular biopsy.
Azoospermia is a relatively common clinical condition that can cause male infertility. To determine whether it is obstructive or non-obstructive azoospermia, a physical examination can be performed. The presence of testicles the size of soybeans or fava beans may suggest non-obstructive azoospermia due to defective spermatogenesis in the testes. If the vas deferens is absent, it is obstructive azoospermia due to ductal incompetence.
Testicular biopsy can also be performed to check for the presence of sperm in the testes and to observe the sperm count. If there is a high number of sperm in the testes but none in the semen, then it is called obstructive azoospermia, and if there are no sperm in the testes, then it is non-obstructive azoospermia.
Whichever type of azoospermia is detected, it needs to be treated aggressively with your doctor to avoid delays.
