Teenage years are a stressful time as your body goes through a number of changes. The hormones your body begins to produce allow you to procreate, but they also change your appearance and behavior.

Progesterone is a hormone that is usually associated with females. However, it is essential in both sexes. In men it is mainly produced by the testes and is required for such vital bodily functions as development of bone density and regulating blood sugar levels. In men, progesterone is converted to testosterone.

Your body contains hundreds of hormones circulating within your blood or stored within various tissues of your body. Maintaining a proper level of each hormone proves important; too much or too little of a single hormone can lead to a hormonal imbalance.

Though testosterone is the dominant male hormone, women have some as well. Women who have high levels of testosterone, however, often have difficulty getting pregnant and carrying a pregnancy full-term. Complications may also arise during pregnancy if you have high testosterone levels.

There are many ways to naturally boost testosterone without steroid use. In fact, taking steroid hormones such as testosterone and its chemical analogs actually shuts down the body's natural production of this important muscle-building hormone.
