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.
Wow – thanks for the great info, JP! I’ve been growing my own herbs for the first time this summer with great success. The spearmint and sage seem to be doing the best, so I’ve been making large amounts of tea out of them. Been drinking quite a bit of both for about 6 weeks now. On a whim, I decided to google positive and negative aspects of ingesting these herbs and found that Sage contains large levels of thujone and should not be ingested in large quantities – yikes! And now I’ve learned from you that spearmint in large quantities may be shrinking my boys and lowering my libido – double yikes!! Who knew? What a shame, as I really enjoyed both as an ‘all day’ beverage. Oh well. Say, do you have any info on French Tarragon as a tea preparation? I really like having fresh herbal beverage to take the place of all the soda I was drinking.
