Testosterone: Functions, Uses, Deficiencies, and Substitution

The document "Testosterone - Functions, Uses, Deficiencies, and Substitution" discusses the role of testosterone as the primary male sex hormone. It is responsible for the development of male reproductive tissues, the promotion of secondary sexual characteristics, and the maintenance of muscle mass and bone density. The paper also explores the uses of testosterone in medical treatments, particularly in hormone replacement therapy for individuals with low testosterone levels. Deficiencies in testosterone can lead to conditions such as hypogonadism and certain types of alopecia. The document also discusses the potential for testosterone substitution in treating these deficiencies, though it notes that this approach should be used with caution due to potential side effects.
