Abstract
Background: Precise placement of the tip of the ET catheter and, accordingly, the depth of ET was proven by several studies to have a significant impact on ET and IVF outcomes. The aim is to assess the relationship between the position of the tip of the inner catheter, the position of the air bubbles (at time, 5 min, 10 min) after embryo transfer and pregnancy rate outcome in ICSI cycles. Patients and Methods: Study design: Prospective observational study. Setting: Fertility unit in Ain Shams University Maternity Hospital (ASUMH). Duration: The duration of the study is expected to be 6 months. Population: Sample Size Justification: The required sample size has been calculated using IBM© Sample Power© version 3 (IBM© Corp., Armonk, NY). Results: The current study revealed that an air-bubble-to-fundus distance >8mm, measured 10-min after ET, was a significant predictor of positive clinical pregnancy at a sensitivity of 71% and a specificity of 55.6%. Conclusion: In conclusion, the current study showed that there is a relationship between air bubbles position and pregnancy rate. Significantly higher clinical pregnancy rates when the air-bubble-to-fundus distance was ≥10 mm after 10 min.
