The endometrium often doesn’t function for women before menopause, in terms of developing a nice good layer to sustain implantation. It’s one of the many fertility problems women have these days. Our sexual reproduction (including the brain-hormonal parts) is dying slowly, possibly from all the plastics and things in our environment. I don’t know the cause but it is. There are many women in their early thirties with premature ovarian failure.
Anyway, it is simple to give estrogen injections and plump up any woman’s uterine lining to the necessary 9mm for implantation and carrying a baby. Pregnancy brings its own hormones, at least for sure it will post first trimester.
