Eggs discharged from the right ovary do not normally travel to the left fallopian tube. However, under certain special circumstances, it is possible for an egg discharged from the right ovary to travel to the opposite side. A normal woman has two fallopian tubes and two ovaries, and usually ovulates on one side of the ovary each month. After the egg is expelled, it will pass through one side of the fallopian tube, where it will meet with sperm to form a fertilized egg. After forming a fertilized egg, it will gradually move towards the uterine cavity and be implanted there. Under normal circumstances, the right ovary normally does not enter the left fallopian tube after ovulation. Under certain special circumstances, it is possible for an egg discharged from the right ovary to travel to the opposite side and be picked up by the left fallopian tube. Women are advised to seek medical attention as soon as possible if they usually have uncomfortable symptoms.
