Uterine size and endometrial thickness and the significance of cystic ovaries in women with pelvic pain due to congestion

Summary. In a group of 55 women with chronic pain due to pelvic congestion measurement by ultrasound revealed they had a larger uterus and thicker endometrium as compared with a group of normal women matched for age, parity and the presence of polycystic ovaries found on ultrasound scanning. Many women with pelvic congestion (56%) were found on ultrasound to have cystic changes in their ovaries which ranged from a classic polycystic pattern to the appearance of clusters of 4–6 cysts in bilaterally enlarged ovaries. It is suggested that uterine enlargement and thickening of the endometrium are caused by oestrogen, either from the effects on the target organs of an increased concentration or of hypersensitivity to oestrogen.
