Question

Gonadotropic hormones are
A.Testosterone and androsterone
B. Estrogen and progesterone
C. LH and FSH
D. Prolactin and luteotropin

Answer 1

Gonadotropic hormones are glycoprotein polypeptide hormones that are secreted by gonadotrope cells of the anterior pituitary of vertebrates. These hormones are part of the complex endocrine system that regulates normal growth, sexual development, and reproductive function. The gonadotropins act on the gonads and control gamete and sex hormone production.

Complete answer:
Option A- Testosterone and androsterone
Testosterone is the male sex hormone secreted from Leydig cells in testis. It stimulates the development of secondary sexual characteristics in males.
Androsterone is the inactive male sex hormone. It is produced from the metabolism of testosterone and is present in urine.

Option B- Estrogen and progesterone
Estrogen is the female sex hormone secreted from ovarian follicles. It stimulates the development of female secondary sex organs.
Progesterone is a steroid female sex hormone, also known as pregnancy hormone because it maintains the inner lining of the uterus which aids in the implantation of the embryo in the uterus.

Option C- LH and FSH
LH stands for the Luteinizing hormone. It stimulates the growth of ovarian follicles in females. It is called interstitial cell stimulating hormone or ICSH and affects the Leydig cells of testes in males.
FSH stands for Follicle-stimulating hormone. It is secreted from the anterior part of the pituitary gland and stimulates the growth of ovarian follicles in females and seminiferous tubules in males. It also promotes spermatogenesis in males i.e. the process of formation of sperms from the germ cells.

Option D- Prolactin and luteotropin
Prolactin is also known as a lactogenic hormone. It is produced by the pituitary gland and stimulates the production of milk in mammary glands during pregnancy.
Prolactin is also known as luteotropin.

So, the correct answer is option C- 'LH and FSH'.

Note: The family of gonadotropin hormones includes the mammalian hormones follicle-stimulating hormone (FSH), luteinizing hormone (LH), and placental/chorionic gonadotropins, human chorionic gonadotropin (hCG), and equine chorionic gonadotropin (eCG).
