GENERAL HISTOLOGY

Detailed explanation-1: -Most hormones are controlled by negative feedback, in which the hormone feeds back to decrease its own production. This type of feedback brings things back to normal whenever they start to become too extreme. Positive feedback is much less common because it causes conditions to become increasingly extreme.

Detailed explanation-2: -This is known as negative feedback. In men, testosterone exerts this negative feedback and in women oestrogen and progesterone exert the same effect except at the midpoint in the menstrual cycle.

Detailed explanation-3: -Negative feedback keeps the concentration of a hormone within a relatively narrow range and maintains homeostasis. Very few endocrine hormones are regulated by positive feedback loops. Positive feedback causes the concentration of a hormone to become increasingly higher.
