After tubal ligation, a woman's ovaries still release an egg each month, there is just no place for it to go, and she will continue to have periods as before. Eggs produced by the ovaries disintegrate in the tube, or in some cases in the space surrounding the tube and uterus (peritoneal cavity).
About 4 out of 100 women will get pregnant during the first 10 years after their tubes are tied. (An egg has less chance of slipping through if you have your tubes closed by cauterisation, or burning.) If you do become pregnant, be sure to see your doctor right away; there's an increased risk that the egg will be implanted in your Fallopian tubesor abdomen, rather than in your uterus

There is no direct relation between tubal blockage and ovulation. Eggs are produced in the ovary, but the eggs cannot go to the womb to be fertilized. The best time to have uterine oviduct imaging is 3 -7 days after menses. Because tubal blockage is caused by inflammation, it often occur with PID, endometriosis and causes endometrial cyst of ovary. Tubal blockage can be treated by laparoscope. Laparoscope can dredge the tubes and separate adhesion. But because the inflammation cannot be eliminated by laparoscope, tubes could be blocked again.
The egg is still released even after a woman has had a tubal ligation, there is no place for it to go. It disintegrates in the tube, or in some cases in the space surrounding the tube and uterus (peritoneal cavity). If an egg does manage to get fertilized, it will very likely implant in an abnormal place ("ectopic"). Unfortunately, technology does not exist to move the child to the safe haven of his mother's uterus. The child does need to be removed, but this should be done in a morally acceptable manner. (This is topic for a different question, but in essence, the principle of "cause and double effect" is employed to justify removing the damaged tube, even though the child is resident inside it. A direct attack on the child by chemical or direct surgical removal of the child is not morally acceptable.) The internal diameter of the tube varies along its length from about 2 to 8 mm.

After tubectomy, the egg will go into the abdominal cavity where it is reabsorbed. There is no pregnancy danger.
