Question

Male sterilization: What is a common issue associated with male sterilization?

a) Rate of fail azoospermia postop
b) Failure rate (after 2 post-op azoospermia)
c) Late recanalization
d) When is it considered success

Answer 1

A common issue with male sterilization is late recanalization, resulting in the potential failure of the vasectomy. Success is typically assessed by consecutive semen analyses demonstrating azoospermia. Though severe side effects can occur, they require further surgical intervention.

Step-by-step explanation:

Common Issues with Male Sterilization

Male sterilization, commonly achieved through a vasectomy, involves the obstruction of the vas deferens to prevent sperm from reaching the ejaculate. One common issue associated with male sterilization is late recanalization, where the vas deferens manages to reconnect over time, leading to failed sterilization. This is different from an immediate postoperative failure to achieve azoospermia, which refers to the absence of sperm in the ejaculate. Male sterilization is considered a success when consecutive semen analyses show the absence of sperm (azoospermia) after the operation, typically after 2 post-operative samples taken at different times.

Another concern consists of severe side effects that may occur, although these are not common. Side effects like impaired heart function, testicular atrophy, and prostate enlargement are very serious but can typically be treated with additional surgeries.
