Table 2 Summary of data published about factor that may affect 3D-ultrasound assessment of menstrual cycle
From: Three-dimensional ultrasound assessment of endometrial receptivity: a review
Author | n | Primary Outcome | 3D Method | Study Design | Findings |
|---|---|---|---|---|---|
Ng (52) | 67 | 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 |
Ng (53) | 645 | 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 | Uterine PI and RI were weakly correlated with endometrial and subendometrial VI/FI/VFI, both in spontaneous and stimulated cycles. |
Chan (54) | 60 | Endometrial volume, and endometrial and subendometrial vascularity | VOCAL | Cross-sectional: oocyte retrieval day | Endometrial and subendometrial VI/FI/VFI are not affected by different r-hCG dosage |
Ng (55) | 32 | Endometrial and subendometrial vascularity in stimulated cycles | VOCAL | Longitudinal hCG +2, hCG +4, hCG +7 | Changes in endometrial and subendometrial VI/FI/VFI are different in excessive responders as compared with moderate responders. |
Raine-Fenning (56) | 48 | 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 | Endometrial and subendometrial VI/FI/VFI were significantly lower in women with unexplained subfertility |
Ng (57–59) | 645 | Endometrial and subendometrial vascularity | VOCAL | Cross-sectional Oocyte retrieval | Endometrial and subendometrial VI/FI/VFI are not affected by women's age, smoking, type and cause of infertility, presence of hydrosalpinx or uterine fibroids |
