Testosterone Insufficiency.

In addition to low libido, the clinical construct of the female androgen insufficiency syndrome includes the presence of persistent, unexplained fatigue and a decreased sense of well-being.

Multiple randomized double-blind, placebo-controlled treatment trials have demonstrated that testosterone improves libido significantly more than placebo.

Doses that provide physiologic to supraphysiologic serum-free or bioavailable testosterone concentrations are safe.
