**Whenever a child is born as a result of IVF methods, the biological/genetic flaws that prevented the parents from conceiving naturally are preserved in that child. So that instead of being weeded out naturally, these genes remain to be passed on to the next generation.**
I didn’t know this. Thanks.
Inability to have children naturally need not imply a genetic defect. Many people have deliberately destroyed what would otherwise have been healthy reproductive systems and presumably adequate genetic material.
