Endometriosis, which has a relatively high incidence among women, refers to the condition where the endometrial tissue is located outside the uterine cavity. This condition can easily lead to infertility. Although endometriosis is a benign disease, it exhibits characteristics similar to those of malignant diseases, primarily manifesting as local infiltration that causes adhesions and can disrupt the function of the fallopian tubes and ovaries. First, it can lead to the presence of chocolate cysts on the ovaries, which can affect the ovulation function of the ovaries. Second, it can sometimes cause adhesions in the fallopian tubes or pelvic adhesions, affecting the egg-pickup function of the fallopian tubes. This prevents sperm and eggs from fertilizing within the fallopian tubes. Even if fertilization occurs, the impaired function of the fallopian tubes may also lead to an increased risk of ectopic pregnancy.
