The 4-Hour Body - An Uncommon Guide to Rapid Fat-Loss, Incredible Sex, and Becoming Superhuman - Timothy Ferriss
Based on the above and my own experiments, I've concluded that some form of animal
product is necessary for proper hormone production. This could be due to the longer-chain fatty
acids, saturated fat, cholesterol, fat-soluble vitamins, or (more likely) a combination of
interdependent elements, some of which we haven't even identi ed. It's also possible that
common vegetarian staples cause the problems, whether soy or gluten. Either way, it's
signi cant that boys born with hypospadias, the opening of the urethra on the underside of the
penis rather than at the tip, are ve times more likely to have vegetarian vs. omnivore mothers.
Dr. Richard Sharpe, director of the Medical Research Centre for Reproductive Biology in
Edinburgh, Scotland, echoes my conclusion about soy:
"I've seen numerous studies showing what soy does to female animals. Until I have
reassurance that it doesn't have this effect on humans, I will not give soy to my children."
