Why does vasectomy cause azoospermia?

Azoospermia is sometimes caused by vasectomy. When a man decides that he no longer wishes to have children, this surgical procedure can be performed as a permanent male sterilization.

In this way, pregnancy is prevented by unprotected sexual intercourse. The man continues to produce sperm in the testicles, but they cannot exit through the duct that transports them because it is sectioned, so they are reabsorbed by the body.

Vasectomy does not affect sexual potency or prevent erection. After the operation and cure, the man can have full sexual intercourse without problems and continues to ejaculate, even if there are no sperm in the semen.

To know if the operation has gone correctly, a seminogram should be performed to check that the sperm count is zero. It depends on the urologist how long to wait, in some cases it is 3 or 6 months to ensure that no sperm remains in the duct that can cause pregnancy. Therefore, after vasectomy, it is recommended to use a condom until two spermograms have confirmed the absence of spermatozoa.
