What is Vasectomy?
Sperms are produced by the two testes. Newly produced sperms are stored in the epididymis. The sperms are transported through the vas deferens and ejaculated together with seminal fluid secreted by the prostate gland, as semen, during sexual intercourse. Pregnancy occurs when a sperm fertilizes an ovum, and the fertilized ovum implanted in the uterus.
Vasectomy is a surgical operation to divide, separate, ligate and seal the two vas deferens. After vasectomy, sperms will continue to be produced by the testes but are no longer travelling out of the body. During sexual intercourse, ejaculation will still occur but the semen will contain only seminal fluid and no sperm. After surgery, the newly produced sperms are absorbed by our body naturally. The residual sperms inside the distal cut end of the vas deferens will be gone after 20 ejaculations, or they will be absorbed after 3 months.
To confirm the success of the vasectomy and contraception, men have to produce a semen sample 3 to 4 months after surgery to confirm that there is no sperm in the semen before the couple can stop future contraception. Before the confirmation of the success of the vasectomy and permanent contraception, the couple still needs contraception.
According to researches, the chance of pregnancy after vasectomy was 0.1-0.2%.
After vasectomy, patients should avoid sexual intercourse for 1-2 weeks. Vasectomy will not affect health or sexual ability. In fact, lots of men and women will feel better about their sex life because they do not need to worry about the possibility of pregnancy.
Vasectomy indications
Treatment
New generation of knife-less / No Scalpel Vasectomy
Before the operation, the doctor applies local anesthetic cream onto the middle surface of the scrotum, to reduce pain during scrotal subcutaneous injection of local anesthetic drug. Disinfection and local anesthesia will be performed after fifteen minutes. As we will use long-acting local anesthetics, the wound will be nearly painless during and after the operation. The new generation of knifeless vasectomy does not require an incision. It only requires small sharp tip forceps to open a small hole in the epidermis. Each vas is taken out carefully, cut, ligate, electrocautery, seal, and return to scrotum. At last, the wound is closed with subcutaneous sutures, sprayed with water repellent cover antiseptic spray and applied with water repellent dressing. Generally, the entire operation takes about ten to fifteen minutes. After surgery, newly created sperm can no longer be able to travel along the vas deferens. The sperm above divided vas deferens ligation usually takes about twenty ejaculations to be cleared, or it may be 3 months to be naturally absorbed.
