Dr. Brent Hanson’s Groundbreaking IVF Research Wins Top Bioanalyst Award

RMA’s Dr. Brent Hanson won the American Association of Bioanalysts’ top research award for proving normal-developing embryos in IVF cycles aren’t negatively impacted by slow-developers. His study analyzed 56% vs. 58.1% euploidy rates in mixed vs. all-healthy embryo groups.

Key Takeaways

Embryo Development Rates Don’t Impact Chromosomal Normalcy in IVF Cycles

Dr. Hanson’s research found normally-developing embryos in mixed groups (with slow-developers) had similar euploidy rates (56%) as embryos in all-healthy groups (58.1%), debunking fears of ‘domino effect’ chromosomal abnormalities.

Day 7 Blastocysts Show Significantly Lower Euploidy Rates Compared to Day 5/6 Embryos

The study revealed day 7 embryos had a 40.6% euploidy rate—over 15% lower than day 5/6 embryos—highlighting the importance of timing in embryo selection for IVF transfers.

IVF Patients with Slow-Developing Embryos Shouldn’t Fear ‘Domino Effect’ on Normal Embryos

Dr. Hanson’s findings reassure 20% of IVF patients affected by slow day 7 embryos: their normally-developing embryos remain chromosomally stable, with no increased risk of aneuploidy from co-cultured slow-developers.
