Ovulation in the human female normally takes place during the menstrual cycle

  1. At the beginning of the proliferative phase
  2. At the mid secretory phase
  3. Just before the end of the secretory cycle
  4. At the end of the proliferative phase

Answer

(4) At the end of the proliferative phase

Solution

As per NCERT, the follicular phase (proliferative phase) runs from the end of menstruation; both LH and FSH attain a peak level in the middle of the cycle (about the 14th day).

⇒ This rapid secretion of LH (LH surge) induces rupture of the Graafian follicle and thereby the release of the ovum (ovulation).

⇒ Ovulation is followed by the luteal phase (secretory phase).

∴ Ovulation normally takes place at the end of the proliferative phase.
