What is a no-scalpel vasectomy?

A no-scalpel vasectomy is a minor operation that consists in severing and blocking the deferens tubes, which transport sperm from the testicles to the penis. A small opening is made in the center of the scrotum, i.e. the pouch containing the testicles, under the penis.

A minuscule titanium clip is installed after which the deferens tubes are cut and cauterized (burned), preventing the sperm from passing through. The procedure lasts from 20 to 30 minutes. It is done under local anesthesia in the doctor’s office. A vasectomy does not affect ejaculation or orgasm, but fertilization becomes impossible.


The majority of vasectomized men will be sterile at their first sperm count, three months after surgery and sometimes more than one sperm count test have to be done before confirmation successful sterilization.

In less than 1% of vasectomy cases, it can happen that deferens tubes naturally heal by themselves before the spermogram control, il it called early recanalization. Fertility is then re-established allowing sperms the right to passage. Late spontaneous recanalization after vasectomy can also happen but the phenomenon is very rare (1 in 1000 patient).

Vasectomy is a permanent contraceptive therefore if you still wish to get pregnant, only reversible contraceptive method should be considered.

No-scalpel vasectomy is a minor surgery that will leave you worriless of birth control and you will be able to resume your daily activities a few days following the intervention.

Vasectomy does not assure immediate sterilization, many spermatozoa are still present in the deferent tubes above the site of the operation. Other method of contraception have to be used until a spermogram confirms the absence of spermatozoa in the ejaculated liquid. Generally, 20 to 30 ejaculations or a three months delay after surgery is requested before proceeding to the sperm count through a spermogram.

Vasectomy is a permanent type of sterilization. There is a surgical method to restore permeability of the different tubes but this surgery named the vasovasostomy is not always effective. Only half of the attempts of ducts reconnection are successful.

The main contraindication to vasectomy is your uncertainty about your desire to have children. Medically, there are a few reasons why a vasectomy cannot be performed.

Vasectomy is a procedure that is considered to have a very low risk of complications. Scrotum bleeding, swelling or pain might occur but studies over many thousands of men show that vasectomy will not cause health issues including cardiovascular disease or cancer.

Sexual function remain unchanged, you will continue to have erections and ejaculations except that the liquid ejaculated will not contain sperms anymore. Note that spermatozoa only make up about 2% of the ejaculated liquid.

It comes mainly from seminal vesicles, small glands situated at the base of the penis, which produce a part of the ejaculated liquid. No difference will be felt on sensations as well.
