Accurate functioning of fallopian tubes
Accurate tubal function involves:
1. The fimbria of the Fallopian tube picking up the egg
2. Transportation of the egg through the Fallopian tube by the cells that line the inside of the tube
3. Fertilization of the egg by a healthy sperm which can penetrate the egg’s protective covering
4. Transfer from the fallopian tube into the uterus where the embryo implants
If implantation occurs in the tube, this results in a tubal pregnancy.
For the above processes to occur, the tube must be open. Many patients have undergone a tubal ligation procedure which has closed the tube. Tubal reversal is a challenging surgery that can be done by an experienced surgeon that allows one to regain the previous anatomy and physiology of the healthy tube. After a tubal reversal, fertility prognosis is based on accurate functioning of the tubes. Other infertility factors may also be present which may hinder conception. (more…)
