Ovarian stromal blood flow changes after laparoscopic ovarian drilling (LOD) in women with polycystic ovary s)

Is to compare the changes in the ovarian stromal blood flow & some hormonal profile (LH,T,FSH & LH/FSH ratio) after laparoscopic ovarian diathermy in women with PCOS. In the ovarian stromal blood flow with serum concentrations of follicle stimulating hormones, luteinizing hormone and testosterone were measured at early follicular phase of menstrual cycle before and first cycle after laparoscopic ovarian diathermy. The ovulation was also evaluated by folliculometry at the first menstrual cycle after operation.After laparoscopic ovarian drilling, there was statistically significant reduction in ovarian stromal blood flow (peak systolic velocity significantly decreased,while resistance index and pulsatiltyindex significantly increased) as well as serum levels of testosterone,luteinizing hormones and LH/ FSH ratio all significantly decreased. These changes were significantly more in those who ovulated after laparoscopic ovarian diathermy. The measurement of ovarian stromal blood flow by 2D power Doppler for women with anovulatory polycystic ovary syndrome undergoing laparoscopic ovarian drilling may provide a useful tool in evaluating the outcome of laparoscopic ovarian diathermy.
