During the luteal phase, which outcome would be MOST likely if a defect prevents adequate progesterone secretion by the corpus luteum?

💡 Explanation

Premature shedding of the endometrium would occur because progesterone maintains the uterine lining during the luteal phase, preparing it for implantation. Therefore, insufficient progesterone causes the endometrium to break down, rather than being maintained by hormonal support.
