This was a very enlightening book about a single hormone that can dictate your whole life. The author describes the biology clearly and gives a lot of examples with his own patients and different studies.

I highly recommend it!

In the politically correct world, there are some who think that men and women were created equal. They believe that whatever differences that we observe are 100% created by society/environment.

I'd love to throw Dr. Charles Ryan's new book, "The Virility Paradox" at people who argue that men and women are equal in almost every respect.

THINGS I LEARNED

Women's serum-testosterone levels are "5-10% of their age-matched male counterparts," according to Dr. Ryan.
Whereas men produce almost all their testosterone in their testicles, women make it in different parts of their bodies.

After 30, both sexes "experience a gradual decline in serum testosterone levels."

Higher fetal testosterone causes the brain to filter out what it considers "noise." Which is why men are often more oblivious than women.

Women who get testosterone injections, get a huge libido surge.
DHEA helps women lose fat and gain money.

Ann Mallen's testosterone experiment changed the way she looked at men (it's worth reading her Washington Post article about it).

Testosterone has little to do with love and may even be inversely proportional to it.

Testosterone makes you want sex but it doesn't help men get an erection. Viagra can make a man hard but it's purely mechanical. For the urge, he needs testosterone (and so do women).

It's worrisome that andropause (the gradual decline in testosterone in aging men) is seen as a problem or "medical condition."

Testosterone prescriptions have increased 10x between 2000 and 2011!

One point the book makes clear is that there seems to be a clear correlation between testosterone and PSA (which measure your risk of prostate cancer). When men supplement themselves with testosterone, they may be fueling their prostate cancer growth.

Testosterone makes us 27% less generous.

Giving testosterone to females makes them less empathetic.

"Marriages are happier if there is less combined testosterone in the couple."

Divorce rate increases when the wife makes more money than the man.

"Testosterone levels are 33% lower in fathers of newborns than non-fathers, while oxytocin levels are 25% higher."

CONCLUSION: If you want to understand testosterone, this book is a must-read.
