Objective: Evaluation of the differences between fertile and infertile females regarding the threedimensional ultrasound markers of ovarian reserve and between the right and the left ovaries in women in each
group. Participants and method: After inclusion, One hundred infertile and one hundred fertile women had a 3D
power Doppler transvaginal scan in the early follicular phase (between the third and the fifth day of the menstrual
cycle). The outcome measures included are: antral follicle count (AFC), small(2-6mm) AFC, larger (7-9mm) AFC,
total ovarian volume (OV) and ovarian vascular indices; vascularization index (VI), flow index (FI) and
vascularization flow index (VFI). The data from the right and left ovaries were compared. Results: The mean AFC,
small AFC (2-6mm), mean VI and mean VFI of fertile group was significantly higher than the infertile group. The
mean OV of infertile group was significantly higher than the fertile group. The difference between the mean of
larger (7-9 mm) AFC and mean FI were statistically insignificant. Regarding the RT and the LT ovaries in the
infertile group AFC, FI and VFI show a statistical significant difference; OV and VI show a statistical nonsignificant difference. In the fertile group; AFC, OV, VI, FI and VFI show a statistical non-significant difference.
Conclusion: AFC especially small (2-6 mm) follicles are the best ultrasound marker of the ovarian reserve.OV
alone should not be considered as a predictor of ovarian reserve. Evaluation of the ovarian stromal vascularity needs
further research as a marker of ovarian reserve. Evaluation of the right and the left ovaries separately is
recommended but further studies are needed to confirm th |
