Removing one side of the fallopian tube can reduce a woman’s chances of conceiving by half. The fallopian tubes are the place where the egg and sperm unite to form a fertilized egg, and the tubes that carry the fertilized egg. After the ovaries discharge a mature egg, the outermost end of the fallopian tube, or umbrella, is used to collect the egg. The egg and sperm are fertilized in the fallopian tube, forming a fertilized egg, which is then transported through the fallopian tube to the uterine cavity, where it lays in the endometrium and forms an embryo. The tube is usually ipsilateral in its egg picking function and rarely succeeds in picking up eggs on the opposite side. If one side of the fallopian tube is removed, it is very difficult for the ovary on the removed side to reach the umbrella of the opposite side of the fallopian tube after ovulation, and only after the ovary on the healthy side ovulates, the umbrella of the healthy side of the fallopian tube completes its egg picking function and fertilization is easy. Only after the ovary on the healthy side ovulates, the umbrella of the healthy tube completes its egg picking function and fertilization is easy. In other words, after the left ovary ovulates, the left ovary will not discharge normal follicles again in the second month, and only the right follicle ovulates and the right fallopian tube is normal to conceive. If one of the fallopian tubes is removed, the chance of conception will be reduced by 50%. This is the reason why many women with ectopic pregnancies are unable to conceive again until several years after surgery because one of their fallopian tubes has been removed.
