I'm happy to explain a bit more about the main theories on why there are more abnormalities with IVF than natural conceptions if you want, but don't want to worry you if you'd rather not know...
But for the sake of anyone stumbling across this thread in the future, I really want to put to bed the idea that there are added risks from ICSI...
A fertility consultant really won't have access to lots more information. Very few (I only know of one) clinics will track patients beyond a confirmed clinical pregnancy (when they see a heartbeat on ultrasound) so simply won't know the outcome of the birth.
Some clinics will try and track live birth data, but that is by writing to patients and asking them to confirm if they have had a live birth. It won't account for a live birth with abnormalities, nor is there any mechanism in the HFEA follow ups to track this.
The only way this can be done is from studies, and then any meta analysis of the studies. These have all shown that there is no statistically significant risk from ICSI over IVF
There is some evidence to show sons born to fathers with sperm problems may inherit the same sperm problems, and you can argue this is a risk from ICSI, because those sons wouldn't otherwise have inherited their father's faulty sperm gene if they hadn't been born
But this isn't relevant to the OP, because ICSI isn't being proposed as a way of overcoming male factor infertility, just to wash the sperm and remove the bad bacteria
