• W2058591019 abstract "ObjectiveEmbryo transfer (ET) is a critical step in the process of in vitro fertilization (IVF); however, half of reproductive endocrinology and infertility (REI) fellows in the United States do not perform ET. Few data exist to refute or support current ET training practices. Our objective was to examine the relationship between trainee status and live birth rate after IVF.DesignRetrospective cohort.Materials and methodsWomen with day-3, fresh, non-donor embryo transfer between 10/1/05 and 4/1/11 at our academic center were identified. Only first IVF cycles were included. Cycles lacking data on embryo quality, ET physician, or birth outcomes were excluded. Embryos were designated “perfect” if they had 8 cells, <10% fragmentation, and no asymmetry. Categorical variables were evaluated with the χ2 test and continuous variables with the Student's t-test. Logistic regression was performed to assess the relationship between ET physician and live birth rate while adjusting for potential confounders.ResultsTabled 1Patient Characteristics and IVF OutcomesAttendingsFellowsP value(N=760)(N=104)Age (years)36.4±.236.0±.4.3Gravidity.9±1.21.0±1.6.3Parity.2±.5.3±.6.7D3 FSH7.5±3.27.5±3.1.9Oocytes10.1±6.310.8±6.3.3Oocytes fertilized6.0±4.46.0±4.1.9ICSI626 (82)81 (78).3Assisted hatching459 (60)57 (55).3Embryos transferred2.2±.72.2±.7.6Perfect embryos transferred.7±.9.8±1.0.3Clinical pregnancy292 (38)40 (38).9Live birth239 (31)35 (34).7Multiple birth48 (6)7 (7).9Values represent mean±SD or N (%).
