What factors affect the efficiency of vasectomy?
The efficiency of vasectomy is very high and beats condoms for the most effective male contraception. Vasectomy is a surgery in which VAS deferens or tubes that transport sperm to sperm, cut and sealed. This prevents sperm from achieving sperm so that although one can still ejaculate the same amount of sperm, it will not contain any sperm. So his partner cannot conceive. The efficiency of vasectomy is almost 100 percent, but may fail to not use protection in the first few weeks or sometimes months after surgery or rarely, because the tube is spontaneously connecting again.
Vasectomy is a safe method of male contraception to be permanent, although it can sometimes be reversed. The procedure can be done with or without cut and the efficiency of vasectomy remains the same. In the cutting method, the surgeon accumulates local anesthesia in the pelvis to dull the patient, and then either perform two cuts, one on both sides of the scrotum or one cut in the center of the scrotum. The surgeon then cuts off you dEfenens and seals them by welding, gripping or closing with electric currents.
In vasectomy without incision, two punctures are produced into the scrotum for access to VAS deferens, which are then cut off and seal. This procedure reduces the risk of infection and bleeding and does not create any scarring. It only takes about five to 15 minutes, compared to an open operation, which lasts about ten to 20 minutes.
Although each method of sealing of the pipes works very well, cauterization vas deferens by electric currents creates the highest efficiency of vasectomy, as it reduces such a slim chance to spontaneously re -connect. It is believed that the sealing of the pipes at both ends increases the efficiency of vasectomy, even if the sealing ends can cause less discomfort. Fascial Inteposition, in which a piece of tissue called a fascial housing is placed between two cut tubes, should also increase the efficiency of vasectomy.
The effectiveness of the vasectomy can be undermined by two events: unprotected sex before all sperm used or reabsorbed, and spontaneous recanalization of VAS deferens. The first problem occurs because vasectomy does not prevent pregnancy immediately. Sperm can still be mixed with sperm around the sealed tube point, and all this must be used before the vasectomy can be trusted as the only way of contraception. Sperm analysis can tell one when sperm is sterile.
The second problem that worsens the efficiency of vasectomy is recanalization when disconnected tubes grow together. This is very rare and usually occurs within the first few months. Recanization may occur when the immune response causes growth deferens, called sperm granuloma, which then develops into a matter called bentitis nosodum. This mass can connect with the second end of the tube on a very rare occasion and allow the sperm to go through.
micro -aid or forming small channels,The sperm can go through can occur as a result of the scar tissue, usually due to poor work by the surgeon. In both types of recanalization, fertility is significantly reduced because VAS deferens passes much less sperm, but pregnancy is still possible. However, these are rare events, and if the patient is waiting for a walk after sperm analysis, the efficiency of vasectomy is almost perfect.
