Aim To investigate the role of 3D‐ultrasound in estimating the likelihood of conception in an IVF programme. Materials and methods We studied a total of 152 women during their stimulation cycle. Apart from conventional 2D‐parameters we assessed endometrial and uterine volume (sub‐)endometrial blood flow (sub‐)endometrial vessel density and ovarian volume by 3D‐ultrasound. Results With regard to subendometrial blood flow on day 1 of the stimulation cycle, all 3D‐indices were significantly lower in the conception vs. non‐conception group. On the day of oocyte retrieval, any difference between the two groups failed to reach statistical significance. The same applied to endometrial volumes. The latter showed a significant corrrelation with uterine size. Ovarian volumes ≤ 3 mm (1 SD below the mean) on day 1 of the stimulation cycle were associated with a nonsignificant lower conception rate. Conclusion Quantitative assessment of spiral artery blood flow and vessel density may be an early predictor of IVF success.
