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.
