Abstract
OBJECTIVE: The purpose of this study was to evaluate the possible association between menometrorrhagia and the level of endogenous estrogen in perimenopausal women. METHODS: A prospective controlled study in which 28 perimenopausal women > 40 years presenting with menometrorrhagia were compared with 28 age-matched (+/- 2 years) women with normal cyclical menstrual periods concerning levels of estradiol and follicle-stimulating hormone (FSH). Neither of the two groups had received sexual hormone treatment at least in 2 weeks preceding the hormonal assessment. RESULTS: The serum level estradiol in the patients was significantly higher than in the controls (0.55 nmol/l versus 0.24 nmol/l), whereas FSH was not significantly different between the two groups (21.2 IU/l versus 11.8 IU/l). Twenty of the 28 patients had performed at histologic examination of the endometrium, and 10 of these (50%) had signs of endometrial hyperplasia. No relationship was found between the endometrial histology and the estradiol level. CONCLUSIONS: An association between a high endogenous estradiol level and menometrorrhagia in the perimenopause was demonstrated. This may have implications for the choice of treatment in this group of women. It is proposed that this type of bleeding disturbances should be controlled by progestins only, and not with combined estrogen-progestin treatment. Suppression of the associated hyperestrogenism could be achieved by use of oral contraceptives or GnRH agonists.
