Tubal ligation consists of preventing the passage of sperm into the tubes, thus preventing fertilization.
The reversal of tubal ligation is not always satisfactory, the factors that may influence are age, time since surgery, and the technique used. In women under 34 years can reach 70% of pregnancies.
Another important factor is the length of the tube after surgery, which must be more than 4 cm.
We can consider reversing a tubal ligation in women under 34 years old and with a residual tube longer than 4 cm.
