The structures in the male reproductive system are the testes, the vas deferens (ductus deferens) and the seminal vesicles, the penis, and certain accessory glands, such as the prostate gland and Cowper’s gland (bulbourethral gland).The testes have a dual function: the formation of spermatozoa from the germinal cells of the seminiferous tubules and the secretion of the male sex hormone testosterone, which induces and preserves the male sex characteristics.
The prostate gland lies just below the neck of the bladder. It surrounds the urethra and is traversed by the ejaculatory duct, a continuation of the vas deferens. This gland produces a secretion that is chemically and physiologically suitable to the needs of the spermatozoa in their passage from the testes.
Cowper’s gland lies below the prostate within the posterior aspect of the urethra. This gland empties its secretions into the urethra during ejaculation, providing lubrication. The penis has a dual function: it is the organ for copulation and for urination.
Anatomically, it consists of the glans penis, body, and root. The glans penis is the soft, rounded portion at the distal end of the
penis.
The urethra, the tube that carries urine, opens at the tip of the glans. The glans is naturally covered or protected by elongated.
