What does the term "sex hormone" mean?
The term "sex hormone" means a hormone (such as estrogen or testosterone) that is in the body to support the growth and function of the reproductive organs, or for the production of secondary sex characteristics (i.e., the secondary sex characteristics of males and females), such as breast development, hair growth, pubic hair, sexual orientation, etc.
Sex hormones in women and men are created from two hormones: estrogen and progesterone. The two hormones are both produced in the same way and work together to produce sex characteristics. However, estrogen is the one most women and men will want to focus on and will give them the most benefit, so we will call her estrogen for the rest of the post.
The hormones that are produced in a woman's body (and in the body of most men) are made using the ovaries. These hormones include progesterone and testosterone. In men, both testosterone and estrogen are produced.
Progesterone is a female sex hormone produced by the ovaries. In women, progesterone is mainly secreted in the body as a byproduct of the menstrual cycle.
This hormone is responsible for the changes that occur in women. It stimulates the production of milk, which gives the female breast a firm and full look.
