The chemical structure of testosterone

Testosterone has gotten some bad press (like estrogen) because of the potential for abuse in professional athletes and body builders.  But most men like to think they have LOTS of testosterone.  It is what makes them build strong, large muscles, have deep voices, and masculine, hairy bodies.  But most of all, testosterone creates desire and libido and without it, our species would not exist.

Testosterone’s Effects

A colleague once said that testosterone turns his wife into “the most beautiful woman ever”.   A woman said, “It wasn’t until I had my testosterone replaced to optimal levels, that I felt like my 20-year-old self again”.   Energy, attitude and that feeling of confidence and satisfaction with life are all related to testosterone.  Some say that testosterone can cause aggression and while this may be occasionally true, the vast majority of patients that I treat feel more relaxed, calm, and open to life and adventure.  Estrogen is a worker and builds and makes things grow, and testosterone says, “OK, I’ll help with that, but let’s relax and have some fun along the way.”  Testosterone contributes to emotional stability and if you see your man get teary eyed or if you feel like crying at the slightest upset, your testosterone is probably low.  When I see John Boehner blubbering away, I think, “This man needs to get his testosterone checked”.  For men, the fall in testosterone with age turns them into grumpy old men with not only little interest in sex, but an overall feeling of apathy, loss of general well-being, ambition, and drive.  They may find their thinking is dull and creativity and sense of adventure is a thing of the past.

While estrogen and progesterone help women with symptoms of menopause, it is testosterone that really gives back that sense of confidence and invincibility – it puts the icing on the cake of HRT.  From “The Hormone of Desire: The Truth About Sexuality, Menopause and Testosterone” by Susan Rako: “Menopause is a journey through poorly charted waters and most physicians approach the possibility of prescribing supplementary testosterone for women suffering symptoms of deficiency with the resistance and ignorance of sailors who believed the earth was flat, and that if they proceeded to sail on, they would fall off.”   I had one patient tell me that her internist told her that she would grow a penis if he gave her testosterone.
