Clinical and hormonal characteristics in women with anovulation and insulin-treated diabetes mellitus.


Clinical characteristics and basal hormonal parameters related to ovulatory function were investigated in 22 diabetic patients with anovulation (group 1) and in nine normally menstruating diabetic patients (group 2) and 45 nondiabetic patients with anovulation (group 3). No significant differences according to control of the diabetes were demonstrated within the two diabetic groups. Groups 1 and 3 did not differ according to classification of anovulation. Group 1 had significantly (P less than 0.01) lower levels of prolactin (PRL), 17 beta-estradiol (E2), thyrotropin (TSH), 3,3',5-triiodothyronine (T3), and thyroxine (T4) than those of group 3, and significantly (P less than 0.01) lower levels of E2 and TSH than those of group 2. The urinary excretion of cortisol was significantly higher in group 1 than in group 2 (P less than 0.05) and group 3 (P less than 0.01). These data suggest a derangement in pituitary-gonadal feedback mechanisms or a depression of pituitary function in anovulatory diabetic patients, and we hypothesize that an increased central/peripheral dopamine and/or cortisol activity in these patients may to some extent influence the hypothalamic-pituitary axis.
