“…46 The vascular changes observed during the entire folliculogenesis process seem to play an important and decisive role in ovulation as well as in maintenance of the corpus luteum. 9,10,12,22,47 Our observations confirm that the changing flow patterns seen in cycling women who ovulate normally are absent in women with PCOS.…”

We conducted a three‐dimensional ultrasonographic evaluation of the size and structure of the ovaries of women who had clinical and biochemical findings suggestive of polycystic ovary syndrome. We carried out a comparative color Doppler frequency and color Doppler amplitude study of the vascular patterns of these ovaries. This study involved 65 women of reproductive age with polycystic ovary syndrome and 25 eumenorrheic women who were not taking hormonal contraceptives and who had a body mass index below 25 kg/m2. Compared to controls, women with polycystic ovary syndrome had larger ovaries and thicker stroma, increased impedance in the uterine arteries, increased stromal vascularity with decreased impedance that persisted throughout the menstrual cycle, and a lack of luteal conversion.

“…A number of studies have showed a relationship between ovarian stromal blood flow early in the cycle and the ovarian responsiveness (11,(26)(27)(28)(29). A lower IOA PI early in the cycle (day 2 or 3) is associated with a larger number of growing follicles (11) and a larger number of oocytes retrieved (29).…”

“…Pulsatility index and RI are measures of resistance to blood flow and are inversely related to blood flow (10,11). The PI is derived from the difference between the peak systolic velocity (S) and end diastolic velocity (D) divided by mean velocity (Velocity m ) (S-D/Velocity m ) (12).…”

Objective : To determine whether ovarian perifollicular blood flow (PFBF) in the early follicular phase (EFP) was associated with treatment outcome. Design : Retrospective longitudinal cohort study. Setting : Tertiary referral centre/university hospital. Patients : Thirty-four women underwent 37 IVF cycles, which resulted in 35 embryo transfers. Interventions : Serial transvaginal scans using power Doppler ultrasound during the follicular phase. Ovarian PFBF of follicles ≥ 5 mm was subjectively assessed using a modified grading system (grades 0-4). Main outcome measures : Ovarian PFBF and pregnancy. Results : Treatment cycles were retrospectively divided into two groups: Group 1 (n = 20) had cycles with at least one small (5-10 mm) or medium (11-14 mm) size follicle(s) of high grade (2-4) PFBF on cycle day 5 or 6 or 7; and Group 2 (n = 17), had cycles that did not. Group 1 had a significantly higher proportion of high grade large follicles in the late follicular phase (35% vs. 21%) (OR 2.0; 95% CI 1.1-3.7) and higher clinical pregnancy rate (47% vs. 12%) (OR 6.3; CI 1.1-35.7) compared to Group 2. Conclusion : High grade ovarian PFBF in the EFP during IVF is associated with both high grade PFBF in the late follicular phase and a higher clinical pregnancy rate.

“…Honnens et al (2008) mostraram em um estudo com vacas submetidas ao tratamento superovulatório com gonadotrofinas um aumento no volume de fluxo sanguíneo e uma marcada diminuição no índice de pulsabilidade da artéria uterina. Um aumento do fluxo de sangue uterino após a estimulação hormonal folicular tem sido demonstrado também em pacientes de FIV na medicina humana (BASSIL et al, 1995;TIITINEN, 1996;STRIGINI, 1995;WEINER, 1993).…”
