The average duration of a normal human **menstrual cycle** is approximately:

  1. 7 days
  2. 14 days
  3. 28 days
  4. 45 days
Show answer and solution

Correct answer: C. 28 days

The menstrual cycle repeats with a periodicity of approximately 28 days, divided into four phases (menstrual, proliferative, ovulatory, luteal).

**Ovulation** in a normal 28-day menstrual cycle is triggered by a sudden surge of:

  1. FSH
  2. LH
  3. Estrogen
  4. Progesterone
Show answer and solution

Correct answer: B. LH

On day 14, a rapid LH surge — triggered by the positive-feedback action of high estrogen — causes the mature Graafian follicle to rupture and release the secondary oocyte. FSH governs follicle growth estrogen rebuilds endometrium progesterone dominates the luteal phase.

In which phase of the menstrual cycle does the endometrium reach its **maximum thickness** of 8–10 mm?

  1. Menstrual phase
  2. Proliferative phase
  3. Ovulatory phase
  4. Luteal (secretory) phase
Show answer and solution

Correct answer: D. Luteal (secretory) phase

**Endometrial thickness:** ~1 mm (menstrual) → 3–5 mm (proliferative, under estrogen) → 8–10 mm (luteal, under progesterone from corpus luteum). The thickened, vascular endometrium prepares for implantation.
