Endometrial and subendometrial vascularity in spontaneous and stimulated cycles |
VOCAL |
Cross-sectional: oocyte retrieval day in stimulated cycles and LH surge day in spontaneous cycles |
Endometrial and subendometrial vascularity was significantly lower in stimulated cycles as compared with spontaneous cycles |

Cross-sectional: oocyte retrieval day in stimulated cycles and LH surge day in spontaneous cycles |
Uterine PI and RI were weakly correlated with endometrial and subendometrial VI/FI/VFI, both in spontaneous and stimulated cycles. |

Endometrial and subendometrial vascularity in fertile and unexplained subfertile women |
VOCAL |
Longitudinal at 2 days interval in follicular phase and 4 days interval in luteal phase |
