The male hormone is a term used to describe two hormones that are essential for male development and reproductive health. ANDROGEN, an 8-letter word, is a hormone that is responsible for the development of male characteristics such as facial hair, muscle mass, and a deep voice. Testosterone, a 12-letter word, is the primary sex hormone in males and is responsible for the development of reproductive organs and sperm production. Both ANDROGEN and testosterone are important hormones for male health and development.
