Summary
Embryo transfer (ET) training varies significantly in US fellowship programs, with many fellows performing few procedures. However, fellow-performed ETs show similar live birth rates to those by attending physicians, suggesting adequate training is achievable.
Area of Science:
- Reproductive Medicine
- In Vitro Fertilization
- Medical Education
Background:
- Embryo transfer (ET) is a critical procedure in assisted reproductive technology.
- Standardized training and competency assessment in ET are essential for fellows in reproductive endocrinology and infertility (REI) programs.
- Variability in ET training may impact fellow proficiency and patient outcomes.
Purpose of the Study:
- To assess current national practices in embryo transfer (ET) training within U.S. REI fellowship programs.
- To compare live birth rates after ET performed by fellows versus attending physicians.
- To identify disparities in ET training experiences among fellows.
Main Methods:
- A cross-sectional survey was administered to U.S. REI fellowship program directors and fellows in 2019.
- A retrospective cohort study analyzed IVF cycle outcomes for embryo transfers (ETs) from 2015-2018.
- Data included fellow ET experience and live birth rates for fellow- versus attending-performed ETs.
Main Results:
- Twenty-one percent of surveyed programs reported no ETs performed by fellows.
- Forty-four percent of third-year fellows had performed fewer than ten ETs during their training.
- No significant difference in live birth rates was observed between fellows (51.6%) and attending physicians (49.4%) for blastocyst ETs.
Conclusions:
- Significant variability exists in the adequacy of ET training across U.S. REI fellowship programs.
- With appropriate supervision, fellows achieve comparable live birth rates to attending physicians in embryo transfer.
- Addressing barriers to ET training and establishing minimum procedural benchmarks for fellows is recommended.
