Most endometrial polyps are detected as a result of infertility screening. The prevalence of endometrial polyps in infertile women is 32% and there is a causal relationship between the two. If ultrasound suggests an endometrial polyp less than 25px in diameter or if a polypoid endometrium is suspected, the physician will advise the patient to repeat the ultrasound or observe after menstruation without rushing to surgery. In this part of patients, the polyps may disappear spontaneously and the patient can conceive naturally with regular obstetric checkups during pregnancy. No special treatment or therapy is needed. If both ultrasound and hysteroscopy of infertility patients reveal large endometrial polyps, the doctor will recommend the patient to have them surgically removed because they affect the implantation of pregnant eggs. Post-operative endometrial repair usually leads to pregnancy in 2-3 months. Hysteroscopic endometrial polypectomy can improve fertility, and the literature reports that 65% of women who have endometrial polyps removed can conceive spontaneously before assisted reproduction. Pregnancy rates range from 43% to 80%. Endometrial polypectomy rarely involves the myometrium, so the risk of uterine perforation, bleeding, and uterine adhesions is low. If the patient has a combination of fibroids, adenomyosis, endometriosis, etc., there is a risk of uterine perforation, bleeding and secondary infection during hysteroscopy due to pelvic adhesions and changes in the morphology and position of the uterine cavity, which may affect pregnancy. As for some patients who are reluctant to undergo surgery, is it possible to conceive directly with endometrial polyps? Does pregnancy necessarily lead to miscarriage? and the chance of miscarriage there is a lack of exact data. Patients who become pregnant without treatment need to have regular obstetric examinations during pregnancy and should be seen promptly if there are any abnormalities.
