On the car radio, I have several times happened upon “infomercial” programs touting the benefits of testosterone replacement therapy for men, broadcast by doctors who specialize in prescribing the drugs. They have lots of wonderful stories about men who feel younger, happier, and more vigorous because of their macho remedies. It’s a tribute to the power of the placebo.
I have been reviewing John Brinkley’s goat gland scam for a presentation on medical frauds.

Blood samples provided testosterone levels and questionnaires (!) asked about the “general, sexual, physical, and psychological health.”
What the scientists found was nothing more and nothing less than a correlation between a low testosterone level and three clinical symptoms (“decreased frequency of morning erection, decreased frequency of sexual thoughts, and erectile dysfunction”). So, one could call it an age-related testosterone deficiency, affecting only a minority (about 2%) of elderly men.
But one shouldn’t name it “andropause” or “male menopause” — and the scientists themselves did NOT use the term in the whole article — because this term immediately suggests a relation to menopause, which is a completely different and natural developmental phenomenon for every woman above the age of 50.
