← Human Body & HealthWhich process limits progesterone production during the luteal phase?
A)Elevated LH receptor downregulation
B)Increased estrogen positive feedback
C)Decreased FSH secretion directly
D)Corpus luteum self-destruction by apoptosis✓
💡 Explanation
Progesterone production declines late in the luteal phase because the corpus luteum undergoes programmed cell death (apoptosis), therefore ceasing hormone synthesis, rather than due to LH receptor downregulation or FSH changes; this terminates the phase.
