Synopsis
Counsel and refer for permanent contraception through autonomous, informed comparison of vasectomy, tubal procedures and reversible alternatives, with correct failure and follow-up advice.
- Permanent contraception requires clear voluntary consent, realistic permanence and failure counselling, and comparison with highly effective reversible methods.
- Vasectomy interrupts the vas deferens, is usually performed under local anaesthesia and does not alter testosterone, erection, orgasm or the visible volume of ejaculate materially.
- Vasectomy is not immediately effective: continue contraception until the service gives written clearance from post-vasectomy semen analysis, commonly first sampled around 12 weeks and after sufficient ejaculations.
Key red flags
Sterilisation is intended to be permanent; reversal is difficult, often privately funded and cannot be promised to restore fertility.
A competent adult does not require partner consent and should not be refused solely because of age, parity, disability or relationship status.
Vasectomy is not immediately effective; continue another contraceptive method until explicit clearance after protocol-timed post-vasectomy semen analysis.
Pregnancy after tubal occlusion has an important ectopic possibility and requires urgent localisation if pain or bleeding occurs.
Pressure during labour, abortion or relationship crisis can undermine voluntary consent; provide private, unhurried discussion whenever feasible.
Partner pressure, fear, financial control or a decision made during crisis requires private assessment and support.
Fever, enlarging haematoma, severe scrotal or abdominal pain and wound infection need prompt surgical review.
Pain or bleeding with a positive test requires urgent ectopic-pregnancy assessment despite the low overall failure rate.
Investigation priorities
Confirm capacity, voluntariness, understanding of permanence, alternatives, failure and material procedural risks.
Management branches
A competent adult requests vasectomy or female sterilisation.
- Explore future family wishes, permanence, alternatives, menstrual or hormone goals and whether anyone is pressuring the decision.
- Compare vasectomy, tubal surgery, implant and intrauterine methods, including procedure, recovery, failure, ectopic risk and uncertain reversal.
