I talked to my clinic today, and my DR and I, in the past, had discussed the PGD testing, as I am older and we'd love a boy. In talking with the clinic today, they require ICSI if you're doing the PGD testing. My question is, is ICSI worth the additional $5000? Has anyone done IVF then ICSI or just in general had better luck with it? Part of me feels that if the IVF doesn't work the first time, that $5000 would really help an additional cycle. Any thoughts?
