Question

Select the incorrect statement
A) FSH stimulates the Sertoli cells which help in spermatogenesis
B) LH triggers ovulation in ovary
C) LH and FSH decrease gradually during follicular phase
D) LH triggers secretion of androgens from Leydig cells

Answer 1

In males, where LH has also been referred to as interstitial cell stimulating hormone (ICSH), testosterone production by Leydig cells is induced. The follicle-stimulating hormone (FSH) works synergistically.

Complete answer:
First we should know about Luteinizing hormones to answer this question. A hormone generated by gonadotropic cells present in the anterior pituitary gland is a luteinizing hormone. An acute increase in LH in females activates ovulation and corpus luteum growth. Now, let us find the answer from the options-

LH has become a luteinizing hormone formed in the anterior pituitary gland by gonadotropic cells. It plays a major role in puberty, fertility, and menstruation.
It activates the corpus luteum ovulation and growth. In males, LH induces the Leydig cells to secrete androgen called testosterone.
FSH is often a follicle-stimulating hormone generated in the anterior pituitary gland through gonadotropic cells.
It helps to control the body's puberty, puberty, pubertal maturation and reproductive procedures.
It activates the testicular Sertoli cells and assists in spermatogenesis, releasing sperm.
The LH and FSH rise steadily during the follicular phase. They promote follicular growth and the release of estrogen by follicular cells.

Thus, the correct answer is option (C) LH and FSH decrease gradually during the follicular phase.

Note: LH promotes theca cells in the ovaries supply Estradiol production with androgens and hormonal precursors. FSH starts follicular development at the time of menstruation, directly impacting granulosa cells.
