Comparison of Bone Morphogenetic Protein-4 (BMP-4) and 7 Levels Between Control and Polycystic Ovarian Syndrome (PCOS) Patients.
The investigators aim to compare the levels of bone morphogenetic protein-4 and -7 (BMP-4 and 7) in blood, follicular fluid and ovarian organ culture supernatant obtained from healthy subjects and polycystic ovarian syndrome (PCOS) patients.
Polycystic Ovarian Syndrome
|Study Design:||Observational Model: Case Control
Time Perspective: Cross-Sectional
|Official Title:||Comparison of Bone Morphogenetic Protein-4 and -7 Levels (BMP-4 and 7) in the Serum, Ovarian Follicle Aspirates and Ovarian Organ Culture Supernatants Between Healthy Controls and Patients With Polycystic Ovarian Syndrome (PCOS).|
Blood samples, ovarian tissue samples, ovarian follicular fluid samples
|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.
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.
