A woman experiences premature luteolysis after IVF; which consequence follows regarding implantation?

💡 Explanation

Premature luteolysis causes a drop in progesterone before the endometrium is adequately prepared for implantation. This occurs because the corpus luteum regresses prematurely, therefore exogenous progesterone is vital to maintain endometrial thickness and vascularity rather than relying on the natural cycle.
