The prostate is an accessory gland of the male reproductive tract, and its presence is universal in mammals. It is committed to the prostatic fluid production and storage, which is released with other semen components during ejaculation. Such fluid contributes to increasing motility and fertility of the spermatozoa, and the neutralization of the vagina, thus playing an important role in fertilization. Few pathological complications, often progressively aggravated with age, can affect this gland (i.e. benign and malignant proliferative changes; all to be described next in this chapter). Nowadays, the neoplastic expansion is the main motivator and contributor for studies on enlightening of growth regulation mechanisms and physiology of the prostate.
