Q152 / 180 · NEET 2016 (Phase 1) · Zoology

Select the incorrect statement:

  • A
    FSH stimulates the sertoli cells which help in spermiogenesis
  • B
    LH triggers ovulation in ovary
  • Correct answer
    C
    LH and FSH decrease gradually during the follicular phase
  • D
    LH triggers secretion of androgens from the Leydig cells

Solution

LH and FSH both increase during the follicular phase.

The first day of menses is identified as cycle day one. Estrogen is at a low point. Therefore, the pituitary secretes FSH and LH, a process which actually begins before the onset of menses. These hormones, in turn, stimulate the growth of several ovarian follicles, each containing one egg.

Hence, the correct answer is option: 'C'.
