Oestrogen replacement therapy relieves many post-menopausal symptoms and has been successfully employed clinically for this purpose for more than four decades. Recently the alleged relationship between oestrogens and cancer has stimulated a re-evaluation of an old oestrogen preparation, oestriol (E3). The dosages of E3 employed appear to vary considerably, and the need was felt to establish the dosage on a scientific basis. Accordingly in the study reported here E3 was administered in various dosages (2, 4, 6, and 8 mg/d) to 52 symptomatic post-menopausal women as oestrogen replacement therapy for a six-month period. Assays of follicle-stimulating hormone (FSH), luteinizing hormone (LH), oestrone (E1) and oestradiol (E2) were performed before and during therapy and vaginal cytology, cervical mucus and endometrial studies were performed during the period of administration. The clinical effectiveness of E3 was found to be directly related to dosage. E3 did not induce endometrial proliferation and proved a poor suppressor of FSH and LH. The ability of oestriol to relieve vasomotor instability and to improve vaginal maturation without inducing notable side effects is sufficient reason for it to be included in the management of the post-menopausal syndrome. |
