Parent Study stopped due to poor recruitment and enrollment

The overall objective of this ancillary study is to obtain skeletal muscle and subcutaneous adipose tissue biopsies from women with polycystic ovary syndrome enrolled in the PULSE Study (NCT01482286).

Muscle and adipose tissues will be appropriately collected and banked for future studies such as to measure expression of candidate genes involved with carbohydrate and fat oxidation and mitochondrial function by RT-PCR, protein content by western blot, enzyme activity by enzymatic assays and to perform functional studies under varying conditions (for example before and after treatment with insulin, testosterone, serum) to quantify insulin signaling and carbohydrate and fat oxidation in primary human cultures.

Inclusion Criteria:

• Enrolled in PULSE NCT01482286

Exclusion Criteria:
