Best answer

Answer: 3. LH and FSH decrease gradually during the follicular phase.

Key idea: LH and FSH rise, not fall, during the follicular phase.

  • FSH acts on Sertoli cells which help spermiogenesis: correct.
  • An LH surge triggers ovulation: correct.
  • LH triggers androgen secretion from Leydig cells: correct.

Statement (3) is wrong, because gonadotropins gradually increase in the follicular phase and peak at mid-cycle.
