Egg viability: genetic testing necessary?

Am 43 y.o., have 2 kids, normal pregnancies. Want to have another child. Someone suggested genetic testing for egg viability.  Necessary or strongly suggested? VERY healthy, active, no known genetic problems/diseases. Pregnant first time around each time tried. Easy pregnancies & births, no problems. Many friends/people seem to be having 'normal' pregnancies at this age w/out testing.

I am 29 years old and just went through my first round of IVF. The RE did NOT recommend genetic testing because we are young. Of the 8 embies we had fertilized, only 2 of them were genetically "normal". I would HIGHLY recommend the genetic testing...so worth it!

My RE told me that at my age (40) 80% of all of my eggs have chromosomal problems.  That is strictly due to age.  I can't seem to find any of those 20% after years of trying.

I am just curious if thing worked out for you, Jen7900.  I just experienced similar results at age 31 with PGD.
