How does low levels of testosterone effect teenage girls?

Answer 1

way too much can make you grow facial hair, or help develop stronger muscles than a female with a lower level of testosterone, but also, testosterone is what makes a man have more sex drive. That is why us women don't want it as much. testosterone is a lot less of our makeup than theirs, but yes we still have it..it's NORMAL. as long as you don't have way too much, your man will like you for it :)

Answer 2

As a physician, I've treated teenage girls with testosterone therapy when their levels are low. The deficiency causes girls (and women) to excessively emotional/moody. Of course this needs to be differentiated with female hormones and even adrenal hormones. But the moodiness can be due to testosterone deficiency.
