Washington, DC- A study presented at the American Society for Reproductive Medicine Society Scientific Congress today examined trends, characteristics and outcomes in oocyte cryopreservation or egg freezing between self-reported race/ethnic groups.
Utilizing data from the Society for Assisted Reproductive Technology, researchers from the Emory School of Medicine analyzed of 29,631 oocyte cryopreservation (OC) cycles from 2014-2016 and found, 66.5%, were in White patients, 9.6% were in Asian/Pacific Islander patients, 7.1% were in Black patients, and 4.5% were in Hispanic patients. While the total number of OC cycles increased yearly among all ethnic groups, the most significant increase was among Asian/Pacific Islander patients with an increase from 245 cycles in 2012, to 1,010 cycles in 2016. Furthermore, Asian/Pacific Islander patients were more likely to perform several OC cycles, as well as perform them later in life. 25.6% of Asian/Pacific Islander patients were likely to do two or more cycles and most commonly performed them between the ages of 37 and 35, as opposed to patients in other ethnic groups who performed OC cycles under the age of 35.
The Study shows, as predicted, oocyte yield and percent maturation were similar among all ethnic groups in patients under 35. Despite low absolute numbers, trends in cancellation and increased gonadotropin dosing are disproportionately seen for minority ethnic groups in comparison to White patients, particularly for Black and Asian/Pacific Islander patients.
“Egg freezing is becoming an increasingly common practice as family structures and planning shift, particularly since people are planning to have babies at a later age. Examining trends in utilization, treatment characteristics and outcomes for different racial and ethnic groups on a national level allows us to begin to appreciate how cultural practices, socio-economic factors and other characteristics may influence family building plans and outcomes. Through studies like this we will begin to understand what may need to be done to provide more equitable access to care and meet patients’ needs” said Valerie Baker, MD, President-Elect of SART.
