Azoospermia /NIL Sperms

Azoospermia is a medical condition in which a man’s semen contains no sperms. It is an important cause of infertility in males. Azoospermia is a condition in which a man has no sperm in his semen. It affects about 1% of males and may be seen in up to 15% of men with infertility.


There are Two Main Types of Azoospermia:

Obstructive Azoospermia: This type of Azoospermia means that there is a blockage in the epididymis, vas deferens, or elsewhere along the reproductive tract. You are producing sperm but it’s not getting released so there is no sperm in your semen.

Nonobstructive Azoospermia: This type of Azoospermia means there is a defect in the structure or function of the testicles or other causes. As a result, there is poor or no sperm production..


The causes of Azoospermia relate directly to the types of Azoospermia. In other words, causes can be due to an obstruction or nonobstructive sources.

Obstructions that cause Azoospermia most commonly occur in the vas deferens, epididymis, or ejaculatory ducts. Conditions that can cause blockages at these sites include:
