I know you ladies were wondering about this hot topic. Needless to say, we will not be gender selecting our embryo and here's why.  This is an article I found. 

Can we choose the sex of our child?

Yes, choosing the sex of your child is technically possible, thanks to advances in fertility treatments that allow doctors to identify male and female embryos. Sex selection is an option for couples who want to avoid passing sex-linked genetic disorders to their children. It also might appeal to parents who have children of one sex and want to have a child of the other sex. (This is sometimes called "family balancing.")

But today's sex-selection options aren't equally effective, affordable, or available. The most accurate sex-selection methods are the most expensive (tens of thousands of dollars) and often mean you have to undergo invasive infertility treatments and take fertility drugs with potential side effects.
