Describe the role of luteinizing hormone in the luteal phase of the menstrual cycle.
Answer
LH surge stimulates corpus luteum formation which secretes progesterone, supporting endometrial proliferation and preparing for implantation.
Step-by-step solution
- Recall that the LH surge occurs at ovulation.
- LH induces luteinization of follicular cells forming the corpus luteum.
- Corpus luteum secretes progesterone, which maintains endometrial proliferation for implantation.
Common mistake: Confusing LH with FSH or attributing LH action only to follicular phase
Concept tested: LH action in luteal phase
