An IVF patient receives exogenous progesterone injections during the luteal phase; which consequence follows concerning endometrial receptivity?

💡 Explanation

Progesterone is critical for preparing the endometrium for implantation; the mechanism involves promoting the development of pinopodes, which are cell surface projections that facilitate embryo adhesion. Therefore, exogenous progesterone enhances pinopode formation, rather than leading to contractions or premature shedding, because it sustains the luteal phase.
