Several tests predict ovarian reserve in women undergoing assisted reproductive technologies. However, the accuracy of these tests in assessing the number of the remaining follicles within the ovary (ovarian reserve) has not been previously validated. The aim of this study was to assess the accuracy of ovarian reserve tests, namely basal and clomiphene-stimulated follicle stimulating hormone (FSH) concentrations and gonadotrophin-releasing hormone (GnRH) agonist stimulation test in predicting the number of the follicles within the ovaries. The ovaries of 22 parous women over 35 years of age who underwent oophorectomy were examined histologically for follicle number. Early follicular phase serum FSH, clomiphene citrate challenge tests (CCCT) and GnRH agonist stimulation test (GAST) were performed in the menstrual cycle prior to the surgery. The predictive value of these tests was then assessed. A positive correlation was detected between basal serum oestradiol concentrations and follicles per unit tissue but no significant correlation was detected between basal and clomiphene-stimulated FSH and follicles per unit tissue. The receiver operator characteristic curves indicated that the clomiphene citrate challenge test was the most accurate of the three tests assessed. In conclusion, none of the tests in this study accurately reflects ovarian reserve.

Adiponectin concentrations in GDM patients' circulation were regulated by changes in glucose and insulin metabolism. A reduction in serum adiponectin levels seems to play a role in GDM patients' insulin resistance.

Laparoscopic surgery causes less tissue trauma than the conventional open surgery; however, we observed no difference between the laparoscopic hysterectomy groups concerning the postoperative inflammatory response. We may prefer laparoscopic hysterectomy instead of total laparoscopic hysterectomy under suitable conditions, since laparoscopic hysterectomy causes the same level of tissue trauma as total laparoscopic hysterectomy, but has the advantage of a significantly shorter operative time. Meanwhile, hysterectomy done by laparoscopy with retroperitoneal lateral transsection of uterine vessels using ligasure is an effective and safe procedure.
