Q

to maintain the normal effects of certain hormones in the body, we can observe the occurrence of down regulation, wherein

A

excess of certain hormones lead to a decrease in the number of hormone receptors

Q

when effects of certain hormones are below normal or there is absence of effects of hormones in the body wherein it was detected as due to decrease in hormone receptor sensitivity the problem present is in
