Anyway, yes, you are right: IVF has a loose connection to miscarriage. Conception involves not sperm meeting egg but fertilized egg implanting in the uterus. Fertilization occurs in the Fallopian tubes. So late-life "fertility" problems involve an uncooperative uterus, which is presumably also unwilling to keep the fertilized ovum around - hence a miscarriage.
So both reflect a problem with Michael's uterus …
… if he even has one.
