contraception through vasectomy

the operation is performed using local anaesthetic, although some men prefer a general anaesthetic. The testicles are shaved. A small cut is made on either side of the scrotum and the surgeon then loops out each vas deferens.The three different vasectomy techniques include:Cutting, and sometimes tying, the vas deferensRemoving a small piece from each vas deferensSealing the vas deferens with heat using a diathermy machine.

After the operation
The scrotum will most likely be bruised and tender after the operation. It is important to rest for a couple of days and avoid running, swimming or any other physical activity. Sex can be resumed after a few days. If the testicles become swollen or painful, or if the wound sites start to weep, there may be an infection. Treatment options include antibiotics and dressings. Occasionally a man will experience prolonged groin tenderness.

Failure rates
The chances of pregnancy after having a vasectomy are around one in 1,000. However, it can take some time for the testicles to reabsorb existing sperm after a vasectomy. It is important to use another form of contraception until tests show zero sperm in the ejaculate. This usually takes three to four months but can occasionally be up to six months.

Reversing the operation
A man usually opts for a vasectomy after he and his partner have completed their family. However, it is common for men entering a second or subsequent relationship to want to conceive with their current partner. Although reversals are nearly always technically possible, they have a variable success rate. The likelihood of a successful reversal depends on the way the vasectomy was performed and the length of time since the operation. As time goes on, the chances of sperm functioning normally are reduced. Some surgeons recommend that a man make sperm bank deposits before having a vasectomy, just in case he changes his mind in the future about having more children. The cost of vasectomy reversal is not covered by Medicare
