Vasectomy, without bistoury

Male Sterilization Method

What is vasectomy?

Vasectomy is a minor operation that consists of sectioning and blocking deferential channels that carry sperm. A small opening is made in the center of the scrotum (i. e. the envelope containing the testes) under the penis. The deferential channels are cauterized, ligsaturated and cut (1 to 2 cm), preventing the passage of sperm that will then be absorbed by the body. This intervention is performed under local anesthesia in the doctor’s office and lasts from 10 to 15 minutes.

What differences with vasectomy without bistoury?

The vasectomy without a drawback is different from conventional vasectomy only through its approach. In addition, it has an anesthetic method that makes intervention less painful. In conventional vasectomy, anesthetic is used by infiltration of scrotum and spermatic cord containing the deferent canal. Two lateral incisions are made, and canals are made to the skin, then sectioned and cached, blocking sperm input into the system. Stitches close the skin of the scrotum.

In vasectomy without a drawback, the physician makes an anesthetic point and a block of the spermatic cord. With a special instrument, it firmly maintains the deferential channel, and then with a second, spells the skin of the scrotum and then gently distracts tissues to the canal. The canal is then brought to the skin to be sectioned, cached and isolated from the other channel. There is much less bleeding, sometimes not at all. No points are needed. The wound closes very quickly and leaves no scar.


During local anesthesia, a slight discomfort can be felt, but once the anesthetic block is realized, there is no more pain. After the intervention, to be honest, we can have some discomfort for which we will take a pain analgesic. However, these disorders are less than conventional vasectomy since there is less tissue reach. Moreover, there is no point. Instructions will be given on recommendations after surgery. It is also available on the website.


The free vasectomy is as safe as conventional vasectomy. The majority of vasectomized males will be sterile in their first spermogram (i. e. sperm test), 3 months after surgery. Sometimes it will take more than one test before sterility is obtained. Rarely (less than 1%), one of the channels will recover before the control spermogram (early recanalization), i. e. both pieces of one cut channel recollect allowing the passage of sperm, thus fertility. Late spontaneous repialization after the control spermogram may occur several years after vasectomy. This phenomenon is very rare (less than 0.1%) and is less often found than with tubular ligature in women (0.4%).


Vasectomy is indicated if you want permanent contraception. As long as you have a desire for pregnancy, reversible contraceptive methods will have to be used.


The main contraindication to vasectomy is your uncertainty about your desire to have children. At the medical level, there are very few reasons for vasectomy. Ex: severe blood coagulation disorder, hernia scrotal (i. e., a piece of intestine in scrotum).


Vasectomy is a minor surgery that lets you stop worrying about contraception. If your work does not involve demanding tasks and physical efforts, you can return to work the following day. Many people suffer a vasectomy on Friday and enjoy the rest of the weekend to return to work on Monday.


Vasectomy does not provide immediate sterilization. Many spermatozoa are still present in the deferent canal above the operation site. You will need to use another method of contraception until a control sperm reveals the total absence of sperm in the ejaculated fluid. Generally, a 3-month period after surgery is requested, or about 30 ejaculations, before spermogram. Vasectomy is a permanent sterilization mode. There is currently surgery to recreate the permeability of the deferential channels. However, this operation, vasovasostomy, is not always effective. Only half of the couples who will try this surgical recanalization will have children.


Complications are rare. Bleeding may occur in the wound or inside the scrotum, forming a hematoma. Wound infections are rare. Scrotum may be swelling or pain. The testicles (congestive epididymite) are possible a few weeks after but transient. Surgical nodule (granuloma) (1%) or chromic pain (0.1%) is very rare. Vasectomy does not cause health problems such as cardiovascular disease or cancer.


As for sexual function, it remains unchanged. The only thing that any vasectomy entails is definitive sterilization, thus the inability to render a pregnant woman. Male hormones and the seminal fluid continue to be produced in the same quantity as before. Vasectomy therefore does not alter the growth of beard hair, musculature, voice, sexual desire, or orgasm.

Erections and ejaculations remained as before vasectomy, except that the ejaculation fluid will no longer contain spermatozoid. Note that sperm represents only 2% of the ejaculate. This is mainly derived from seminal vesicles (small glands at the base of the penis) producing part of the ejaculation fluid.
