There are huge numbers of testosterone creams, pills, and injections as well as ads convincing men they are in need of these products. There are also thousands of lawsuits filed against the manufacturers of the various testosterone therapies claiming the drugs caused several severe cardiovascular side effects including heart attack and stroke. With this knowledge, Men’s Journal published an article describing natural ways men can boost their testosterone through diet so as not to take on unnecessary risks. One suggestion made was to increase vitamin D intake which could increase testosterone level. Men should always use caution and discuss diet changes with their doctor.
Testosterone is a hormone produced in the male testes. During a boy's pubescent years (ages 9 to 14), there is an increase in production that leads to male secondary sexual characteristics such as a deeper voice, more muscle mass, facial hair growth and enlargement of the Adam's apple (among others). Some teenage boys experience these puberty changes at later ages than others. The timing of puberty is often genetically determined (through heredity), but other factors can play a role in delaying it, such as poor nutrition, physical trauma and certain diseases. Stimulating testosterone production naturally is possible in teen boys, although in rare cases hormone therapy may be needed to trigger and complete puberty.
