Question

Select the option that shows correct statements:

1. Corpus luteum secretes progesterone.
2. Only FSH attains a peak level in middle of cycle.
3. LH surge induces rupture of graafian follicle.
4. Luteal phase of menstrual cycle is also called proliferative phase.

Options

• Only (ii) is correct.

• (i) and (iii) are correct.

• Only (iv) is correct.

• (ii) and (iv) are correct.

Answer 1

(i) and (iii) are correct.

Explanation:

• Corpus luteum secretes large amounts of progesterone (true).
• Both LH and FSH rise and attain mid-cycle peaks; it is false that only FSH peaks in the middle of the cycle.
• A rapid mid‑cycle LH surge induces rupture of the Graafian follicle (ovulation).
• The luteal phase is the secretory (post‑ovulatory) phase, not the proliferative phase.
