Not all patients with endometriosis need surgery. For example, in clinical practice, adenomyosis, a type of endogenous endometriosis, causes increased menstrual flow, progressive menstrual pain and infertility, but it is not necessary to remove the uterus surgically. The IUD is a highly effective progestin that can counteract estrogen after being inserted into the uterine cavity, so it will cause the endometrium to shrink and the ectopic lesions to atrophy, which can lead to treatment. Some patients with endometriosis need surgery, for example, ovarian chocolate cysts are found and cause severe menstrual pain, which may lead to the eventual rupture of the cysts as they increase in size and cause serious consequences. Surgery is recommended for timely treatment.
