Change in Progesterone Sensitivity Index Before and After Metformin Treatment. Primary · 12 weeks following start of metformin treatment

The progesterone (P4) sensitivity index is defined as the percent change in 11-hour LH pulse frequency before and after P4 and estradiol administration for 7 days, divided by the day 7 mean serum P4 concentration. We compared the P4 sensitivity index after metformin administration to the baseline P4 sensitivity index, using Wilcoxon signed-rank test.

Sponsor's own description

Many, but not all, girls with high levels of the male hormone testosterone go on to develop polycystic ovary syndrome (PCOS) as adults. Women with PCOS often have irregular menstrual periods, excess facial and body hair, and weight gain. PCOS is also a leading cause of difficulty becoming pregnant. The investigators do not understand why some girls with high hormones develop PCOS and others do not. In a previous study by our group, some girls with high levels of male hormones had abnormalities in the secretion of another hormone, called luteinizing hormone (LH), that are often seen in women with PCOS. However, another group had normal LH secretion. The girls with the abnormal LH secretion had higher levels of another hormone, called insulin, than the girls with normal LH secretion. The investigators will test whether metformin, an insulin-sensitizing agent, changes the effects of high male hormone levels in adolescent girls, specifically by looking at their LH secretion response following metformin treatment.
