    Purpose: To evaluate an embryo transfer method based on the transabdominal ultrasound associated with the previous uterine length measurement performed though vaginal ultrasound, which consists of the distance from the external cervical os to the fundal endometrial surface plus the half of the distance of the endometrial lumen. The pregnancy and implantation rates in patients undergoing assisted reproduction treatment were evaluated. Methods: The study evaluated 200 patients undergoing intracytoplasmic sperm injection (ICSI) cycles, in which the pituitary blockage was achieved though GnRH agonist or antagonist and FSH and hCG were used for follicular growth and final maturation respectively The patients were split into two groups based on embryo transfer method used. Every patient in which the embryo transfer was based on previous uterine length measurement (ULM group, n=50) was matched with three cycles in which embryo transfer was performed though standard ultrasonographicguidance (US group, n=150). The outcomes of the studied groups were evaluated. Results: Experimental groups were similar for the female age; the number of aspirated follicles, the number of MII retrieved oocytes, number of transferred embryos, endometrium thickness and the causes of infertility. The groups were also equal regarding the easiness of transfer (95.5% vs 95.6% for US and ULM groups respectively, p=1.000). However, both the implantation (11.9% vs 30.6% for US and ULM groups respectively, p<.0001) and the pregnancy rates (26.0% vs 54.0% for US and ULM groups respectively, p=.001) were significantly higher in the ULM group. Conclusion: Our findings demonstrated that the embryo transfer method based on the transabdominal ultrasound associated with the previous uterine length measurement should be performed routinely in assisted reproduction centers, since it is able to significantly improve pregnancy and implantation rates.
