Background The aim of this study was to evaluate arterial and venous intraovarian blood flow in infertile patients. Methods Seventy‐six FSH stimulated cycles in 39 patients participating in a timed intercourse or iui program were studied. Transvaginal color and pulsed Doppler measurement of the dominant follicle and corpus luteum resistance index (RI), pulsatility index (PI), peak systolic velocity (PSV), maximum venous velocity (MVV) and serum p levels during mesoluteal phase were recorded. Velocimetric parameters were established and then used to classify ovarian function in normal ovulatory cycle (NOV; n = 52), luteal phase defect (LPD; n = 15) and luteinized unruptured follicle (LUF; n = 9). Results The luteal PSV and MVV in the nov and LPD cycles were significantly higher (NOV: 24.3 ± 12.2 vs. 13.1 ± 6.5 and 8.1 ± 3.30 vs. 3.6 ± 1.1; LPD: 29.8 ± 10.3 vs. 14.4 ± 4.8 and 5.7 ± 1.5 vs. 4.3 ± 1.2) and luteal RI and PI were significantly lower (NOV: 0.45 ± 0.06 vs. 0.55 ± 0.08 and 0.62 ± 0.15 vs. 0.83 ± 0.22; LPD: 0.46 ± 0.05 vs. 0.54 ± 0.06 and 0.62 ± 0.10 vs. 0.81 ± 0.15) than follicular ones. LUF cycles did not show significant changes during the ovarian cycle (follicular vs. luteal PSV; MVV; RI and PI: 14.4 ± 4.8 vs. 14.9 ± 7.3; 4.3 ± 1.2 vs. 4.2 ± 2.1; 0.47 ± 0.07 vs. 0.58 ± 0.12 and 0.66 ± 0.12 vs. 0.89 ± 0.29) and no ‘luteal conversion’ of the Doppler signal was identified. There was significant correlation between luteal MVV and serum p ( r = 0.36). Conclusions Arterial and venous intraovarian blood flow remain unaltered during LUF cycles and P levels correlate with luteal MVV. This makes Doppler an effective noninvasive test to assess ovulation and luteal function.
