A direct quote from Wikipedia -
"Testosterone is a steroid hormone from the androgen group. Testosterone is secreted in the testes of men and the ovaries of women. It is the principal male sex hormone and the "original" anabolic steroid. In both males and females, it plays key roles in health and well-being. Examples include enhanced libido, energy, immune function, and protection against osteoporosis.
Like other steroid hormones, testosterone is derived from
CHOLESTEROL." (Emphasis mine).
We are all aware of the dangers of high cholesterol levels, I believe it to be timely to remind that there are levels which are also too low.
All things must be kept in moderation
