　　1. Surgery
　　
　　Currently, there are three types of birth control surgeries available: vasectomy, vas deferens plugging, and non-obstructive vas deferens IUD. The latter two surgeries are based on traditional ligation.
　　
　　Surgery that is always associated with trauma and pain sounds a bit scary. However, the whole process of birth control surgery only takes 20 minutes, no stitches are needed, and the recovery time is only two days. There are almost no scars after the surgery. The minimal trauma and fast recovery are beyond the imagination of many people.
　　
　　Non-obstructive vas deferens IUD: Major majors in early August this year media reported one after another“ male "IUD" technology, its scientific name is non-obstructive vas deferens IUD. This method is to place a filter made of special material (nylon material) inside the male vas deferens. sperm Intercept it for contraceptive purposes.
　　
　　When contraception is no longer needed, the filter can be removed and normal reproductive functions restored. One of the benefits of this procedure is the avoidance of epididymal stasis that can occur after traditional ligation surgery. There are currently three phases in progress clinical verify.
　　
　　Vasectomy: Cutting off the vas deferens, which is the tube that carries sperm, definitely prevents pregnancy. The starting ends of the two vas deferens are located in the scrotum and can be felt from outside the scrotum and pulled into the scrotum. skin Therefore, the doctor only needs to make a small opening in the scrotum as big as a grain of rice and cut off the vas deferens to achieve the contraceptive effect.
　　
　　Many people worry that after cutting off the vas deferens, will there be no semen or much less semen? No. On average, men ejaculate about 2ml of semen each time. Among them, seminal vesicle gland fluid and prostatic fluid account for more than 90% of the semen volume. This part will still be ejaculated. After ligation, the epididymal fluid and sperm, which account for less than 10% of the semen volume, are blocked. Therefore, the amount of semen will not be affected much. When pregnancy is needed, vas deferens anastomosis can be performed, and the recanalization rate can reach more than 90%.
　　
　　Disadvantages: Some men will experience epididymal stasis and discomfort after surgery.
　　
　　Vas deferens plugging: The difference between this method and ligation is that it is not necessary to cut the vas deferens. Instead, a special material (main component is carbolic acid) is injected into the vas deferens. The vas deferens is stimulated to form scars and harden, thus losing its channel function.
　　
　　Disadvantages: Since the amount of injected material is not easy to control, some people's vas deferens is blocked for too long, causing needle-like discomfort at the surgical site. This method has been abandoned by the vast majority of clinicians.
