  2. Gender Selection

Hi, I'm just wondering... for the purpose of gender selection, is it better to do PGD-FISH or aCGH? Which would you recommend?

I've heard some sources say that PGD-FISH is 99% accurate with gender selection and aCGH is only 90% accurate with gender selection? How true is this?

Thank you for your interest in our gender selection program. As with everything in life, there are pros and cons to every treatment or treatment method for embryo screening. Our laboratory has switched from using FISH to aCGH to screen embryos for aneuploidy (which is an abnormal number of chromosomes) and gender simultaneously. We believe the benefit to aCGH is a more comprehensive genetic evaluation than gender alone. FISH is not capable of screening all 24 chromosomes, and although some may argue that FISH gives a better reading for the X and Y chromosome than aCGH, it is a limited test. In other words, we don't feel it's beneficial to know the gender of an embryo only without know the other chromosomes are present. Hope that helps!
