IVF is not a fertility treatment. Before IVF you can't conceive normally. During IVF you cannot conceive normally. And after IVF you cannot conceive normally.
It does not cure infertility.
“If you need to treat a malfunctioning cervix or correct a progesterone deficiency, that’s true healing and curing because it restores your organs and systems to normal healthy function.”
FWIW, I casually know a woman who took some sort of fertility treatment pills and she had 4 kids at once. Several years later after she conceived naturally, the marriage broke up. Sad story.
