Women are turning to testosterone, but what does the science actually say? - Medical Xpress

A recent BBC report described women posing as men to get hold of testosterone gel, hoping to improve their menopause symptoms, because female testosterone products are not easily available to them. But why is the appetite for this predominantly male hormone exploding and are there risks involved? Testosterone is usually thought of as the defining male hormone. It is linked to puberty, muscle development and reproductive function. But this overlooks an important biological reality. Women also produce testosterone, and it plays important roles throughout the body.
