When a couple decides not to have more children, despite the safe, permanent contraceptive methods of birth control, many men opt for vasectomy surgery that allows for simple and efficient male sterility. With the advancement of reproductive medicine, it is possible to reverse this situation.
The vasectomy reversal is a surgical procedure performed through a small opening in the scrotal. With the aid of a microscope, we perform the realigning of the channel (vas deferens) ligated in the vasectomy. The anesthesia is applied by means of rachidian blocking and the patient is discharged on the same day. This method does not subject the woman to any treatment. The chances of multiple pregnancy drop and of conception occurring naturally increase.

Vasectomy, also called deferentectomy, is a surgical method of contraception created by blocking the sperm output. With this procedure, which is quick and safe, man becomes sterile. The male genital organ has a canal leaving the organ adjacent to the testicle, the vas deferens, responsible for disposing of sperm. Vasectomy closes this channel and prevents the passage of gametes for semen. The operation lasts about 20 minutes and does not require hospitalization.
