Biospecimen Retention:   Samples With DNA
Blood samples, ovarian tissue samples, ovarian follicular fluid samples

Estimated Enrollment: 50
Study Start Date: February 2010
Estimated Study Completion Date: February 2011
Estimated Primary Completion Date: February 2011 (Final data collection date for primary outcome measure)
Healthy control subjects and patients with polycystic ovarian syndrome will be recruited for the study.

Detailed Description:

Female patients at ages 20-35 diagnosed with polycystic ovarian syndrome and age-matched healthy control subjects will be enrolled in this study.

Blood samples will be obtained at early follicular phase during doctor's visit from PCOS patients and control subjects.If the patient is amenorrheic at the time of visit, both random blood samples and another sample at early follicular phase after induction of withdrawal bleeding with progesterone.

Follicular fluids will be retrieved during oocyte pick-up procedure in patients undergoing assisted reproduction for PCOS and control IVF patients whose infertility is not PCO related.

Samples from ovaries will be collected at operation from PCOS patients and control subjects if they already undergo any gynecologic laparotomi operations.

Collected samples will be cultured for 7 days and BMP-4 and -7 levels will be measured in the culture fluid of the samples using ELISA method.
