Options
- Afollicles do not remain in the ovary after ovulation
- BFSH levels are high in the luteal phase
- CLH levels are high in the luteal phase
- Dboth FSH and LH levels are low in the luteal phase
Correct answer
D. both FSH and LH levels are low in the luteal phase
Step-by-step solution
No new follicles develop in the luteal phase of menstrual cycle. It is because during this phase, Luteinising Hormone (LH) and Follicle Stimulating Hormone (FSH) levels decrease. Instead, the already ruptured follicle closes after releasing the egg and forms a corpus luteum during luteal phase, which produces progesterone.
