Do keep in mind

that many women are ttc with partners who are older & there is a somewhat higher incidence of autism in children of older fathers.

Also, most women move to DE having been told it is an egg issue. REs are loathe to test men beyond the standard semen analysis & are happy to proclaim eggs are the fertility issue with donor eggs being the solution. While this may be true overall, they are going to miss male factor issues in some cases & that may explain some issues with the resulting children some of the time.

There are no clears answers in this area & I'm far from qualified to offer any stats on any of this, but those are factors to at least consider.
