Where do 'testicles' get their name from (would you believe it's from Roman law)? Can testicles actually break? Is it normal for one testicle to hang lower than the other? How can you actually measure the size of your testicles? Have you ever wondered why these sensitive organs are outside your body and not safely tucked inside your belly (like women's ovaries)? At which points in a man's life do his testicles grow? Can you make them grow by taking drugs? What is the correlation between the number of sexual partners and testicular size? All these questions and many, many more are answered in this book!
