Abdominal pain is a common clinical symptom of gynecological diseases, but there are many diseases that cause abdominal pain, and these diseases are often closely related to infertility in women. The so-called infertility is mainly a barrier to fertilization, while infertility is mainly a barrier to embryo and fetal conception after the pregnant egg has been deposited. Such as: hymenal atresia, vaginal atresia, severe congenital cervical stenosis or atresia, atretic uterine malformation, stumpy uterine cavity with blood accumulation, these disorders occur mainly after puberty with cyclic lower abdominal pain without menstrual flow, menstrual blood lurking in the reproductive tract for a long time, and even cause tubal accumulation of blood to infertility. Uterine adhesions occurring after abortion, spontaneous abortion or postpartum placenta residue scraping, manifested as postoperative cyclic abdominal pain and secondary amenorrhea, causing infertility. Chronic cervicitis and cervicocervicitis caused by purulent bacteria manifests as lower abdominal pain with dysmenorrhea, and abnormal inflammatory secretions destroy the internal environment of the vagina, resulting in infertility. Non-tuberculous or combined endometritis, sometimes with lower abdominal pain and menstrual abnormalities, or irregular uterine bleeding, often causing infertility. Uterine fibroids manifesting as vague pain in the lower abdomen, heavy menstrual periods, and irregular vaginal bleeding, on the other hand, affect conception and pregnancy to varying degrees with the location, size, number, and degree of the fibroids. Endometriosis, which manifests as progressive dysmenorrhea accompanied by pain during sexual intercourse and pain during defecation, can cause ovulation disorders or luteal insufficiency resulting in infertility due to extensive foci in the uterus, fallopian tubes, ovaries and pelvis, adhesions, and especially ovarian endometriosis destroying the cortex. Tubal inflammation is the most common cause of infertility, accounting for about 20%-30% of infertility. The main manifestation is persistent.
