On the eve of the seventh day of the seventh month, the Cowherd and the Weaving Maiden can meet on the Magpie Bridge and tell each other how they feel about each other. If there is no magpie bridge, across the Milky Way, the Cowherd and the Weaving Maiden will have to wait for another year. For women who are preparing for pregnancy, the fallopian tubes, as the place where sperm and egg meet, build the magpie bridge of life. If the fallopian tubes are blocked, the sperm and egg can not meet, which will cause infertility. What happens when the fallopian tubes are blocked? Normally, the ovaries of women of childbearing age release a mature egg every month, and if it meets a sperm in the fallopian tube, the two can combine to form a fertilized egg. A blocked fallopian tube is like an obstacle between the sperm and the egg. The sperm can’t get through, the egg can’t get through, and the two can’t meet, causing infertility. Even if the two are successfully combined, the fertilized egg is more difficult to move to the uterus, and may even form an ectopic pregnancy, endangering the life of the pregnant woman. So what is a blocked fallopian tube? The fallopian tubes are a pair of slender and curved tubes located in the upper edge of the broad ligament of the uterus, the inner side and the uterine horn is connected to the outer end of the free, and close to the ovaries, the total length of 8-15 cm. according to its structure and function, from the outside inward is divided into four parts: ① fallopian tube funnel – the outer end of the funnel shaped inflated, the edge of the umbrella thin; ② fallopian tubes jugular abdominal –The fallopian tubes are divided into four parts: (1) the funnel – the outer end is funnel-shaped expansion, the edge of the thin umbrella; (2) the fallopian tubes pot-belly – thin-walled cavity is large, is the place of fertilization; (3) tubal isthmus – for the expansion part of the rear of the thin part of the tubes; (4) uterine part of the uterus – in the uterine horn through the uterine wall. Tubal blockage causes: 1. gynecological inflammation such as vaginitis, cervicitis, uterine inflammation, adnexitis, pelvic inflammation and other gynecological inflammation, due to long-term inflammatory stimulation so that the tubes are congested with blood and edema, thickening, hardening, lumen adhesion, narrowing until blockage, resulting in tubal obstruction of infertility. 2. Abortion Abortion is the main cause of tubal obstruction. Due to mechanical stimulation, improper operation or incomplete abortion and other reasons, abortion surgery often leads to secondary inflammation and infection; with the successive invasion of various pathogenic bacteria, the uterus spreads to the fallopian tubes and pelvis, resulting in tubal infection, causing tubal obstruction. 3. Long-term vaginal bleeding Due to gynecological tumors, ovarian dysfunction, uterine pathology and other reasons, such as excessive menstruation, prolonged menstruation, menstrual leaking or even two menstrual periods in a month and other irregular vaginal bleeding phenomenon, and did not treat in time, and over time, secondary inflammatory infections, resulting in tubal lining ulceration, adhesion, blockage. 4. Unclean sex Unclean sex is the trigger of many diseases. Patients are often infected with various diseases due to unclean sex, such as gynecological diseases, sexually transmitted diseases, etc. These diseases may be secondary to tubal inflammation, which may cause different degrees of tubal obstruction and lead to infertility. 5. Other factors such as tubal endometriosis, tubal pregnancy, abdominal surgery, appendicitis surgery, taking and placing the birth control ring, pelvic tuberculosis, etc., can cause tubal infections, resulting in tubal wall congestion, edema, adhesion and blockage. Symptoms of tubal blockage: Generally speaking, there are no typical symptoms of tubal blockage, and the most common manifestation is infertility. The fallopian tubes have the important roles of transporting sperm, ingesting eggs and transporting fertilized eggs to the uterine cavity. Obstruction of the fallopian tube can hinder the passage of sperm and fertilized egg, leading to infertility or even ectopic pregnancy. If tubal blockage is caused by pelvic inflammatory disease, it can be accompanied by lower abdominal pain, lumbago, increased secretion, and painful intercourse. 1. Infertility The fallopian tube itself is attacked by disease and damage, forming blockage and causing infertility. 2. Dysmenorrhea Stagnant dysmenorrhea due to pelvic congestion, most of them have abdominal pain one week before menstruation, and the closer the menstruation, the worse the pain will be until the onset of menstruation. 3. Irregular menstruation The fallopian tubes are adjacent to the ovaries. Generally, fallopian tube diseases do not affect the function of the ovaries, and have no effect on the amount of menstruation, but only when the inflammation spreads to the ovaries and damages the function of the ovaries, then abnormal menstruation will occur. 4. Abdominal discomfort Different degrees of pain in the lower abdomen, mostly hidden discomfort, lumbar back and sacral pain, swelling, and a feeling of falling, often aggravated by exertion. Due to pelvic adhesions, there may be pain in filling or emptying of the bladder and rectum, or other symptoms of vesico-rectal irritation, such as frequent urination, urgency and heaviness. 5. Others, such as increased leukorrhea, pain during sexual intercourse, gastrointestinal disorders, fatigue, impaired or intolerable labor, psychoneurotic symptoms and mental depression.
