Summary
Plasma gonadotrophin levels were measured at frequent intervals in six post-menopausal thyrotoxic women treated with carbimazole. All patients showed an increasing follicle stimulating hormone/luteinizing hormone (FSH/LH) ratio as the thyroid hormone concentrations fell to normal and then into the hypothyroid range. Although the increased FSH/LH ratio was primarily due to a rise of FSH, two patients had a rise of both gonadotrophins. It is suggested that menstrual irregularities occurring in premenopausal women with disorders of thyroid metabolism may be related to similar changes.
