Most believe that the most important number to look for is how many eggs and embryos are retrieved.
But new research shows that there may be other factors at play, especially for black patients, who have a 14 percent lower live birth rate than white women, according to data from a large clinic in Washington, DC.
Some of the discrepancy can be explained by the fact that the African American patients were more likely to be older, with a higher BMI.
However, the researchers of the study warn much of it is likely caused by biological factors that we don’t understand because black women are under-studied in medical research.
