ABSTRACT: An appropriate and easy embryo transfer has a direct impact on pregnancy rates. Proper evaluation of the uterocervical axis and uterine depth are necessary for suitable embryo transfer. The aim of this study was to assess the appropriate time for cervical axis evaluation and uterine measurement. A total of 124 patients undergoing IVF treatment were included in the study. They were divided equally into two groups. In group I (62 women), uterine cavity depth was measured and the uterocervical axis was determined on day 2 or 3 of the menstrual cycle, and in group II (62 women) at the time of oocyte retrieval. There was a statistically significant difference in clinical pregnancy rates between the two groups (P = 0.006). Thirty-four women became pregnant in group I (64.2%) versus 19 women in group II (35.8%). In conclusion, uterine cavity measurement is necessary for suitable embryo transfer. It seems that the time of measurement significantly affects clinical pregnancy rate in IVF cycles. The best time for uterine measurement is on day 2 or 3 of menstruation.
