Delayed menstruation after uterine fibroid surgery is considered to be an endocrine disorder, as surgical stimulation can lead to ovarian ovulation being affected, which may result in delayed menstruation. If a woman is >40 years old, she should also consider whether she is in the perimenopause, when ovarian ovulation decreases, so that delayed periods and changes in menstrual volume often occur. Women who have sex with menstrual delay also need to exclude whether they are pregnant. It is recommended that women who have had fibroids removed routinely use contraception for more than 2 years, because there will be scarring on the surface of the uterus after fibroid removal, and short-term pregnancy may lead to uterine rupture, and the risk of late pregnancy is relatively high, so it is not recommended that women become pregnant in the short term.
