Question

At menopause there is rise in urinary excretion of

• A. LH
• B. MSH
• C. FSH
• D. STH

Answer 1

The correct option is C FSH

Menopause
Menopause is a natural process in which the menstrual cycle ceases in women around the age of 45-50 years. Reasons for menopause

Reasons for menopause are as follows:
1)Changes in the pituitary gland.
2)Changes in the hypothalamus.
3)No follicles are left in the ovaries.

Estrogen level during menopause
The estrogen level during menopause is less as the number of follicles that secrete estrogen in the ovary is very less.

FSH
level during menopause Estrogen has a negative feedback mechanism on the secretion of gonadotropins, especially FSH from the anterior pituitary. Less estrogen causes the release of large quantities of FSH which is excreted in the urine.

STH
Growth hormone or somatotrophic hormone (STH) is secreted by the anterior pituitary gland. It is required for proper growth and metabolism.

MSH
Melanocyte-stimulating hormone (MSH) is secreted by the anterior pituitary gland. It protects the skin from ultraviolet rays and is required for the development of pigmentation.

LH
Luteinising hormone is secreted by the anterior pituitary gland. Rapid secretion of LH leading to its maximum level during the mid menstrual cycle is called LH surge. It induces rupture of the Graffian follicle and thereby the release of the ovum (ovulation).

Final answer
(A) FSH
