Vasectomy under Local (LA) or General Anaesthetic (GA) – Information for GPs


Vasectomy is a surgical procedure for male sterilisation or permanent contraception. During the procedure, the male vas deferens are severed and then tied or sealed in a manner so as to prevent sperm from entering into the seminal stream (ejaculate) and thereby prevent fertilisation.

Referral criteria / commissioning position

Vasectomy under Local Anaesthetic (LA)

NHS Scarborough & Ryedale and Vale of York CCGs routinely commission vasectomies carried out under LA in non-secondary care settings.

Vasectomy under General Anaesthetic (GA)

NHS Scarborough & Ryedale and Vale of York CCGs do commission vasectomies under General Anaesthetic in secondary care only in the following circumstances:

  • Previous documented adverse reaction to LA
  • Scarring or deformity from previous scrotal surgery or trauma that makes vasectomy under LA difficult to achieve
  • History of coagulation disorder, inguinal scrotal hernia or cryptorchidism
  • Large varicocele or hydrocele
  • Where patients have previously had vasectomy on the NHS, have subsequently had a reversal of vasectomy (privately or on the NHS) and again wish to undergo vasectomy

Fear of the procedure, or patient choice are not adequate reasons for requesting vasectomy under GA, unless supporting mitigating factors are submitted to the IFR panel by the requesting clinician.

Patients who do not meet the criteria outlined above, can be considered on an individual basis where their GP or Consultant believes there is an exceptional clinical need that justifies deviation from this policy. In those instances an application should be made to the IFR panel

Summary of evidence/rationale

It is recommended that men who request a vasectomy are fully assessed and counselled before the procedure is given; including taking the medical history of both partners to ascertain if the procedure is indeed the most appropriate intervention.

Men should be counselled about the permanency of the procedure and variable success rates for reversal. Additional counselling is recommended for men under 30 years. Advice should also be provided to men about the possibility of chronic testicular or scrotal pain after vasectomy.

Most vasectomies are carried out under local anaesthetic. This means only the scrotum and testicles will be numbed and the patient will be awake for the procedure. The procedure should not be painful but may feel slightly uncomfortable. Most men will only need a local anaesthetic.

The RCOG guidelines recommend a general anaesthetic is used where:

  • There is a history of allergy to local anaesthetic
  • Surgery has been carried out before on the scrotum or genital area

The RCOG guidelines also recommend:

  • A ‘no-scalpel’ approach, as there are lower levels of complications such as bleeding, pain and infection;
  • The use of fascial interposition or diathermy;
  • That clips are not used, due to high failure rates;
  • That local anaesthesia is used wherever possible;
  • Effective contraception be used before the operation and until follow-up tests show that the vasectomy has been successful;
  • Practitioners must be trained to the level of the FSRHC requirement
