The operation is usually performed under local anesthesia. At the patient's request or for medical indications, intravenous sedation (medication-induced sleep) may be used.
During the operation, the surgeon gains access to the vas deferens through a small incision or puncture, after which it is cut and both ends are hermetically sealed. As a result, sperm cells no longer enter the ejaculate, which provides the contraceptive effect.
On average, vasoresection lasts 20–30 minutes. After it is completed, a sterile dressing is applied to the wound. The patient remains under medical supervision for several hours, after which, provided they feel well, they can return home the same day.
