Effect of diabetes compensation on ovarian function recovery in women of reproductive age with type 1 diabetes mellitus

Hypothesis/aims of study . The adverse effects of type 1 diabetes mellitus on the female reproductive system have been proved by many studies. There is still conflicting literature on the impact of diabetes and other factor compensation on ovarian function in women with type 1 diabetes mellitus. Study design, materials and methods . The current analysis was undertaken to study the effects of diabetes compensation on ovarian function in women with type 1 diabetes mellitus. In order to this, 180 individuals aged 20 to 40 years were examined. The main group consisted of 112 diabetic patients with primary ovarian insufficiency, the comparison group included 68 women with type 1 diabetes mellitus and a normal ovulatory cycle. After 18–24 months following the therapy aimed to compensate diabetes, 63 patients with ovarian insufficiency were re-examined. The examination included determination of blood glucose, glycated hemoglobin (HbA1c), FSH, LH, prolactin, estradiol, total and free testosterone, 17-hydroxyprogesterone, dehydroepiandrosterone sulfate, dihydrotestosterone, progesterone, and sex hormone-binding globulin (SHBG) levels, as well as ultrasound examination in the first and second phases of the menstrual cycle. Results . Association of ovarian insufficiency with HbA1c level and the dose of insulin was found. Patients in the main group experienced a decrease in FSH and SHBG levels, an increase in the ovarian volume and the number of antral follicles compared to those in diabetic patients with a normal ovulatory cycle. In patients with decompensated diabetes and ovarian insufficiency, after the compensation of diabetes, the recovery of the ovulatory cycle was observed in 61.8 % of cases. Conclusion. Ovarian function in women with type 1 diabetes mellitus depends on HbA1c level and the dose of insulin. Diabetes compensation in women with type 1 diabetes mellitus contributes to the recovery of ovulation in 61.8 % of cases.
