There are several key hormones that play important roles in the body:
Estrogen: This hormone is primarily associated with the development of female sexual characteristics and the regulation of the female reproductive system.
Testosterone: Known as the male sex hormone, testosterone is responsible for the development of male reproductive tissues and the maintenance of male secondary sexual characteristics.
Insulin: Insulin helps regulate blood sugar levels and facilitates the uptake of glucose by cells for energy production.
Thyroidhormones: These hormones, including thyroxine (T4) and triiodothyronine (T3), regulate metabolism and influence growth and development.

Progesterone: Progesterone plays a key role in the menstrual cycle and pregnancy, as well as in the development of the mammary glands.
