Objective To identify predictors of the ovarian response to clomiphene citrate (CC) in infertile patients with polycystic ovary syndrome (PCOS). Methods We performed a prospective cohort study of infertile patients with PCOS. The participants underwent assessments of their physical, endocrine, and metabolic characteristics, and treatment with CC at an initial dose of 50 mg/day and a maximum of 100 mg/day between days 3 and 7 of their menstrual cycles. Participants who ovulated were identified as responders and those who did not as non-responders. Results Of the 72 participants, 48 (66.7%) were identified as responders and 24 as non-responders. Sex hormone-binding globulin (SHBG) (odds ratio 1.022, 95% confidence interval: 1.000–1.045) was found to be associated with the ovarian response to CC using logistic multivariate regression analysis. Receiver operating characteristic analysis also showed that SHBG was a significant predictor of the response to CC (area under the curve 0.799). Conclusion We have shown that SHBG is the best prognostic indicator of an ovulatory response to CC. However, larger prospective studies, in which more variables are assessed, are required to confirm this finding and to identify appropriate cut-off values.

Background: The study was conducted to assess the association between endometrial blood flow pattern assessed with colour Doppler around the day of HCG administration and IVF outcome following GnRH antagonist down regulated cycles.Methods: It was a prospective, cohort study. Total of sixty-eight patients undergoing IVF-ET/ICSI were recruited in the study. All the patients underwent controlled ovarian stimulation with a step-up protocol, and GnRH antagonists were used for down-regulation. Transvaginal ultrasound measurements of all patients were performed on the day of HCG injection. A 6.5 MHz pulsed Doppler system was used for blood flow analysis. Bilateral uterine arteries, pulsatility index and resistance index were calculated along with uterine artery peak systolic velocity on both sides. Endometrial blood flow was analysed by detecting flow in the intra-endometrial or the adjacent sub-endometrial regions.Results: Baseline FSH in pregnant group was lower (6.29) than non-pregnant group (7.36). The overall pregnancy rate was 45.6% (n=31) and the ongoing pregnancy rate was 41.1% (n=28). Total of 57 patients out of 68 patients had both good endometrial and sub-endometrial blood flow. The overall pregnancy rate in this group was 47.3%. Similarly, in patients who had minimal endometrial and sub-endometrial blood flow the pregnancy rate was 37.5%. There was no significant correlation between pregnancy outcomes and the color flow Doppler parameters such as average uterine PI, average uterine RI and right/left uterine peak systolic velocity.Conclusion: Uterine artery PI, RI and PSV has no role in predicting endometrial receptivity and thus pregnancy outcome in IVF-ET cycle, however those patient with good endometrial and sub-endometrial flow have higher pregnancy rate than those with minimal flow rate.
