Your Fertility

by Leigh Ann Woodruff, March 19, 2012

A specific gene may have a lot to do with your chances of IVF success, particularly if you are undergoing treatment at an older age.

According to an ovarian aging study published in March 2012 in the medical journal PLoS One, a genotype (the genetic make-up of a trait) of the FMR1 gene preserves a woman's ability to produce eggs well into the 40s. Conducted by the Center for Human Reproduction in New York, the study compared egg yields during in vitro fertilization (IVF) in women above age 40 with varying FMR1 genotypes and sub-genotypes.
