In castrated male there is under-secretion of:
Correct answer: A. Testosterone
- A. Testosterone
- B. FSH
- C. LTH
- D. STH
Explanation
After the initiation of development, the sex organs in the foetus produce them, and their level rises fairly consistently until puberty. After puberty the supply of LH (ICSH), and therefore, the level of testosterone, remains constant. In the foetus, it initiates the development of the sex organs. At puberty it brings about development of the male secondary characteristics and promotes the sex drive. The castrated male fails to develop secondary sexual characteristics and his body tends more towards the form of the immature female.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
