Testosterone therapy can improve the overall health and feeling of well-being of aging men, improving sex drive, mental functions, and energy levels and reducing the risk of cardiovascular disease.―Library Journal
This is a good text for those who wants to understand the basics of testosterone. It is quite comprehensive, covers all aspects of effects of testosterone, including its function in females. I found it easy to read, clear and informative and definitely recommend it as a starter book to those who are interested in the topic.
