A vasectomy (the sterilization of a man) is one of the safest and most reliable contraceptive methods. During this small procedure, the spermatic ducts on both sides are severed so that the sperm formed in the testicles can no longer enter the urethra and be expelled during an orgasm. This leads to permanent infertility in men. A vasectomy has absolutely no influence on the sensation of orgasm, the desire to have sex, the ability to have an erection (penis stiffening), or ejaculation.
Basically, vasectomy is suitable for any man whose family planning is complete. As the procedure is difficult to reverse, a vasectomy should only be decided on and performed, if a man or a couple no longer wish to have children. However, if a desire to have children should arise again, reversing the vasectomy may be attempted. This procedure is called a vasovasostomy and is, however, much more complex than a vasectomy.
At alta uro, the procedure is performed under local anaesthetic in the vast majority of cases and takes place at our outpatient clinic. Should you prefer a brief anaesthesia, we can organize this for our patients at the Merian Iselin Clinic. A small skin incision allows the surgeon to identify and mobilize the spermatic ducts (vasa deferentia). In order to prevent them from growing together once again, we use a technique that guarantees maximum security. The spermatic ducts are not only cut through, but a piece of about 1 cm length is cut out. The ends of the spermatic ducts are then sclerosed with electric current, tied off, and finally sutured to different layers of tissue. The skin is then closed with the help of self-dissolving sutures.
Infertility is not an immediate consequence of the procedure. After a successful vasectomy, fertile sperm may still be present in the seminal fluid for several months. That’s why, in the beginning, additional contraceptive measures are still necessary. About 2-3 months after the vasectomy, a control of the ejaculate should be carried out. Before the first control of the ejaculate, a minimum of 20 ejaculations should have taken place. If there are no sperm left, further contraception is unnecessary. If there are still some sperm present, a further sperm sample should follow some time later.
