Is it serious to have a blocked fallopian tube?

Fallopian tube obstruction is a common gynecological disease that affects women's normal reproductive function. Therefore, when a woman is diagnosed with fallopian tube obstruction, she must undergo fallopian tube unblocking surgery. Only in this way can the male sperm and the female egg combine to become a fertilized egg, and the male sperm has a chance to enter the female fallopian tube. So is it serious if the fallopian tube is extremely blocked?

Blocked fallopian tubes is a disease. The fallopian tubes are a pair of long, trumpet-shaped tubes, one on each side, about 8-15 cm long. According to its shape, it can be divided into four parts.

① Interstitial part or uterine part: It is the part that goes into the uterine wall and is narrow and short.

② Isthmus: It is a section outside the interstitial part, with a narrower lumen and a length of about 3 to 6 cm.

③Ampulla: Just outside the isthmus, the lumen is wider and about 5 to 8 cm long.

④ Infundibulum or fimbria: It is the end of the fallopian tube, opening into the abdominal cavity. The free end is funnel-shaped and has many whisker-like tissues, which have the function of "picking up eggs".

The important function of the fallopian tube is to transport sperm, pick up eggs, and cyclically transport eggs discharged from the ovaries or fertilized eggs to the uterine cavity once a month. The movement of sperm and egg is a combination of the movement of the sperm itself, the automatic peristalsis of the fallopian tube, and the swaying of the villi growing on the fallopian tube epithelium. It takes about five days for the fertilized egg to be transported to the endometrium for implantation. These physiological activities are controlled by ovarian hormones. During ovulation, due to the influence of high levels of estrogen, the direction of fallopian tube peristalsis changes from proximal to distal, pushing sperm from the uterine horns to the ampulla of the fallopian tube.

At the same time, the secretion of the isthmus inner membrane increases, and its fluid moves toward the abdominal cavity, thus facilitating the movement of sperm. When the ovary releases the egg, the fallopian tube funnel "picks up" the egg and makes it float in the fallopian tube fluid. In the ampulla of the fallopian tube, a large number of folds facilitate the sperm and egg to stay and fertilize here. Then, under the action of progesterone, the fertilized egg moves into the uterine cavity through the peristaltic contraction of the fallopian tube and the movement of cilia. When any part of the fallopian tube becomes blocked or dysfunctional, it will affect the fertilized egg from reaching the uterine cavity smoothly, causing it to implant and develop in the narrow part of the fallopian tube, forming a tubal pregnancy, which is also an ectopic pregnancy.
