This antibody crosses through placenta and breakdown the red blood cells of the infant. ...Read more

Why rhd incompatibility of the mother and fetus doesn't affect the present fetus but subsequent pregnancies?
See below: The incompatibility occurs when the mother is exposed to the blood of the new baby. This usually occurs at delivery. The mother then makes antibodies to that "foreign substance" and this can adversely affect the next pregnancy as the mother's immune system will see it as a "foreign" body and want to get rid of it. This problem is usually treatable with an injection at the birth of the first child. ...Read more

Can MRI effect the development of sperm cells or impact sperm in anyway, pre-pregnancy that could contribute to chromosomal translocation?
No: I am unaware of any evidence in the scientific literature that a standard diagnostic MRI has any adverse effect on sperm, developing sperm, or on a person who is pregnant or the fetus. The literature suggests that the strength of the mr field at diagnostic levels does not affect dna synthesis, cell cycle, or proliferation kinetics in a fetus. ...Read more
