Biology Question on Human Endocrine System

When both ovary of rat are removed then which hormone is decreased in blood

A

Oxytocin

B

Prolactin

C

Estrogen

D

Gonadotrophic releasing factor

Answer

Estrogen

Explanation

Solution

The correct option is (C) : Estrogen

A neuropeptide secreted by the posterior pituitary is called oxytocin. Milk production mostly utilises prolactin. The anterior pituitary produces GnRH, which promotes the release of LH and FSH. The blood plasma level of oestrogen will be impacted if both ovaries are removed because theca interna cells of Graafian follicles generate oestrogen. The hormone known as oestrogen is primarily responsible for controlling how female accessory reproductive organs, secondary sexual characteristics, and sexual behaviour grow and develop.
