Yes. The vasectomy is reversible, being an act technically feasible and feasible.
In cases of reversion with up to 10 years of vasectomy, pregnancy rates reach more than 70%; in individuals with more than 10 years of vasectomy, the pregnancy rate is close to 44%. Currently, this procedure has been successfully performed in patients with more than 20 years of vasectomy, with a good recovery of the male potential to produce a natural pregnancy.
As time goes by, however, the increased pressure in the epididymis generates fibrosis and obstructions arise, not at the place where the ligature was made, but below that point, which complicates the surgery. Although the repermeabilization index is always the same, the spermatozoa do not appear. Then, instead of taking that segment and connecting the two vas deferens, it is necessary to take them to the epididymis at a point closer to those with fibrosis, promoting a connection that leaves the area that is obstructed.
However, more important than the time of vasectomy in the chances of getting pregnant is the age and fertile potential of the partner. In women up to 30 years of age, the reversal produces about 64% of pregnancy; from 30 to 35 years, 49%; from 36 years, the rate is 30 to 40%. Thus, evaluation of the ovarian reserve (with hormones and transvaginal ultrasonography) and tubal potential and functioning (through hysterosalpingography) are of fundamental importance before deciding to reverse vasectomy or not.
