I do PGD for other reasons (screening for a birth defect) but with PGD you can also find out the gender. My embryos all survived the testing, and the thaw but they were the best quality (day 5 hatching grade A). I wouldn’t PGD test the day 3 embryos on day 3, because the results are less reliable and the embryos have not grown to the point of cell differentiation between baby and placenta. By day 5, you can guarantee that the embryologist takes the cell to be tested from the placenta and not the baby. I did two rounds of PGD with day 3 testing and neither of those cycles worked. I HIGHLY recommend day 5 testing if you’re going to do it. Also, be prepared to lose at least half of your embryos due to abnormalities even if you’re young. PGD adds a whole new element to IVF, and you run the risk of not having anything or much to put back. I know this isn’t easy to hear, but it was my life for the last year and I know a lot about it. I didn’t do it for gender selection, but if that’s what you really want to do , good luck! I like you, (and probably every mother out there) would love to experience the joy of a son and a daughter. But getting there by PGD could take some time, $ and heart break. And in reality, if you’ve been ttc for a while, does it really matter what the gender is when they put that beautiful baby in your arms?
