| Popis: | Objective To evaluate the relationship between the pregnancy rate (PR) and the positioning of the intrauterine catheter at embryo transfer (ET) under transabdominal ultrasound (US) guidance in in vitro fertilization (IVF) cycles. Study design Prospective data analysis of 281 consecutive US-guided fresh ETs performed by a single physician at Yeditepe University Hospital IVF Center, Istanbul, Turkey, after controlled ovarian hyperstimulation between April 2012 and March 2013. The length of the uterine cavity (A), the distance between the fundal endometrial surface and the tip of inner catheter (B), the distance between the fundal endometrial surface and the air bubbles (C), and the pregnancy rates (PRs) were recorded. Results The mean age of the patients was 33.25 ± 5.5 years. Of all transfers, 115 (40.9%) resulted in a clinical pregnancy. With regard to distance (C), the clinical intrauterine pregnancy rates were 65.2%, 32.2% and 2.6% in the 10 mm between the fundal endometrial surface and the air bubbles, although this did not reach statistical significance. Between those patients who conceived and those who did not, there was no significant difference in terms of the distance between the fundal endometrial surface and the tip of inner catheter, the ratio of A/B or the ratio of B/C. Conclusions The final position of the air bubble used as an identifier of the position of the embryo at ET can be determinative for PR, although it cannot be predicted. Clinical pregnancy rates appeared higher in cases with air bubbles closer to the fundus and the optimal position of the air bubble seems to be a distance of |
