"It's very difficult to understand this group of symptoms and what is causing them. When we tested hormones, on the contrary of that which I would have expected, the testosterone levels were in range.

There's a molecular signal that reveals that these subjects [PFS sufferers] are different from normal people, and from hypogonadal individuals."
