A woman experiences recurrent luteal phase defects (shortened post-ovulatory phase). Which hormonal mechanism explains why this condition disrupts endometrial receptivity?

💡 Explanation

Inadequate progesterone production during the luteal phase disrupts the normal preparation and maintenance of the endometrial lining. Because of this disrupted signaling, the endometrium does not properly mature to support implantation; therefore, implantation fails, rather than a direct effect of FSH, estrogen, or androgens on follicle development.
