The purpose of this clinical guideline is to provide guidance to clinicians who offer vasectomy services. This guidance covers pre-operative evaluation and consultation of prospective vasectomy patients; techniques for local anesthesia, isolation of the vas deferens and occlusion of the vas deferens during vasectomy; post-operative follow-up; post-vasectomy semen analysis PVSA and potential complications and consequences of vasectomy.

Fertility Options After Vasectomy
Ejaculates produced by 82 men between 6 and 19 days after removal of approximately 5 cm of vas deferens were assessed specifically for motility of residual spermatozoa. Several of 23 ejaculates produced 6 to 8 days after vasectomy still contained spermatozoa of the quality and number likely to produce pregnancy. By 13 to 15 days, however, all or the great majority of residual spermatozoa were dead, and in only 1 of 50 men were there numbers of motile spermatozoa possibly compatible with fertility. The results seem to justify more extensive surveys to confirm the absolute or biologic limits of the viability of spermatozoa in the terminal portion of the human male reproductive tract, anticipated here to be 16 to 18 days, as a suggested basis for a standard postvasectomy protocol. Second, these data support the choice of the 3rd postoperative week as the earliest rational moment to confirm the absence of motile spermatozoa, or in their presence to suspect an incomplete block.
Viability of spermatozoa in the human ejaculate after vasectomy.
Vasectomy is currently one of the most common methods of sterilization in the United States. After your vasectomy, if you change your mind about having children, there are two procedures that can help you have a child with your partner. The two options are: a vasectomy reversal or sperm aspiration prior to in vitro fertilization IVF.
Vasectomy is a birth control method in which part of the vas deferens is surgically removed to prevent sperm from entering the ejaculate. Vasectomy does not affect the testicles nor the production of testosterone. Sexual desire and the ability to have an erection and an orgasm are not affected. Because the sperm itself makes up a very small proportion of the ejaculate, a vasectomy does not affect the volume or appearance of the ejaculate.
