male sterilization
More and more men think that their wives should not get pregnant in October, and it is troublesome to use condoms, and other contraceptive methods are not satisfactory. For such a man, vasectomy is very suitable. However, just like female sterilization, don't think it is reversible, and both husband and wife should think twice before acting.
Vasectomy is a simple and quick operation, which can usually be performed in outpatient department. This is often as long as the pubic hair on both sides of the scrotum is shaved three times, and no special preparation is needed.
After thoroughly disinfecting the scrotum, the doctor will inject local anesthetic into this part and then cut it open. The incision is not long (about 1 cm long) and is located about 5 cm above the testis, where the scrotum joins the lower abdomen. Because the vas deferens is close to the skin surface, it is not difficult to find. It looks like a thick yellow line. The doctor tied up the two parts of the vas deferens and cut a short piece of one centimeter long; Stop the bleeding and then close the incision. So are other vas deferens. The operation time on both sides is only about 12 minutes, so you can go home directly. But wear a scrotum support (much like the lower body protector worn by athletes) and avoid lifting weights and strenuous physical activities for about ten days. It's best to take a day off after vasectomy, and then everything will be as usual.
If you want to understand the role of vasectomy, it is necessary to look at male anatomy. Obviously, after vasectomy, sperm cannot reach the penis.
Vasectomy is to cut off the vas deferens from testis to penis, so that sperm are trapped in testis and men are infertile. After the operation, the man produced sperm as usual, but could not discharge it; The produced sperm is decomposed and absorbed in the body. However, men can still get pregnant weeks or even months after vasectomy because there are still a small amount of sperm in their reproductive tract; This is different from women, who are infertile as soon as their fallopian tubes are ligated (because the eggs can't pass the obstacle at all).
Vasectomy is a very safe and effective sterilization method, but at present it can only be performed on men with normal sexual life history and satisfactory sexual life, and this operation must be regarded as a permanent sterilization method.
The research on sterilization is far less than oral contraceptives, mainly because no pharmaceutical company will support sterilization as a contraceptive method. However, people are now conducting several follow-up studies on men after surgery to see if there will be any interesting or long-term effects. In Britain, the legality of vasectomy must have been questioned before 1960. Only later, because many men underwent this kind of surgery, we had a lot of topics to study.
