What the procedure involves
Local anaesthetic is given, the vas is brought to the surface through a tiny puncture made with a special instrument, divided and sealed on each side. No scalpel incision is made and no stitches are needed. You walk out shortly afterwards.
- Around fifteen minutes, fully awake and comfortable
- No cut, no suture, minimal bleeding
- Back to desk work the next day
- Far less involved than female sterilisation, which needs abdominal access
What it does not change
Sexual desire, erections, orgasm and the appearance and volume of semen remain the same — sperm are a tiny fraction of ejaculate volume. Testosterone production is unaffected. Vasectomy provides no protection against sexually transmitted infections.
The rule people forget
You are not sterile immediately. Sperm remain in the tubes beyond the blocked point for weeks. Continue contraception until a semen analysis at around three months confirms zero sperm. Pregnancies after vasectomy almost always trace back to this step being skipped.
Treat vasectomy as permanent. Reversal is possible but is a longer microsurgical operation with no guarantee of restored fertility.
Vasectomy (NSV) — common questions
Does vasectomy cause weakness or reduce sex drive?
No. It blocks sperm transport only. Hormones, erections and libido are unaffected — the weakness people describe is not physiological.
Is vasectomy reversible?
Reversal is technically possible with microsurgery but success is not guaranteed, and falls with time since the vasectomy. Choose it only if you consider your family complete.
How soon can I resume sex?
Usually after about a week, with contraception continued until the three-month semen test confirms clearance.
Is vasectomy safer than female sterilisation?
It is a shorter procedure, done under local anaesthesia, without abdominal entry, and with fewer complications.
