Background:

Vasectomy is a common surgical procedure for male sterilization.
The need for effective and safe methods to ensure post-vasectomy sterility is crucial.
Spermicidal agents offer a potential adjunct to surgical methods.

Purpose of the Study:

To evaluate phenyl mercuric nitrate as a potent spermicidal agent for use during vasectomy.
To assess the safety and efficacy of phenyl mercuric nitrate injection in preventing sperm viability post-vasectomy.

Main Methods:

Phenyl mercuric nitrate solution (0.02%, pH 7) was prepared.
2-5 ml of the solution was injected into the lumen of each vas during vasectomy.
Seminal analysis was performed one to two weeks post-operation to assess sperm viability.

Main Results:

Phenyl mercuric nitrate demonstrated potent spermicidal activity upon contact.
The injection procedure was simple, adding no significant time or complications to vasectomy.
No viable spermatozoa were detected in seminal counts conducted one to two weeks after the operation.

Conclusions:

Phenyl mercuric nitrate is an effective and safe spermicidal agent when used as an injection during vasectomy.
This method provides rapid and complete elimination of sperm, ensuring successful male sterilization.
The procedure is minimally invasive and well-tolerated, with no reported harmful side effects.
