Vasectomy is a surgical procedure that cuts or blocks the vas deferens, the channels that carry sperm from the testicles to the urethra. In this way the sperm is devoid of spermatozoa and ineffective for fertilization. It is an effective form of birth control, but is it really 100% safe? Spermatozoa have an average life of about 3 months.
Soon after the vasectomy, it is therefore possible that the seed is still fertile. During this time, analyzes are performed to ascertain that there are no more spermatozoa and that the sperm is "clean". Until then, it is good to continue using other types of contraceptives. Ignoring this waiting time is one of the main reasons for pregnancy after a vasectomy. It is not the only one. It happens that the procedure does not work and fails to block the ducts. If you perform the prescribed analyzes, identifying the problem quickly is easy enough. At this point, just repeat the whole thing.
It is much more difficult to identify the so-called recanalization. In this case, the ducts reform and create a new connection. In fact, the vasectomy is self-deprecating. This raises a last question: can the procedure be canceled? Most vasectomy operations are reversible. Nevertheless, only 3-6% of men retrace their steps. To cancel the effects of vasectomy, it is necessary to sew up the cut ducts or eliminate the blockage.
This solution is simpler and even more effective. Alternatively, it is possible to join a flap of ducts directly to the canal that carries sperm from the testicles. The procedure is more complex and has a lower success rate.
