Reproductive System

Joint purpose is to produce offspring. Organ system which functions in creating offspring.

Primary Sex Organs (Gonads)

Testes. Produce gametes.

Sex Hormones

Hormones that regulate the development and functioning of reproductive organs and that stimulate the devolopment of male and female sexual characteristics. For males it's testosterone.

Accessory Reproductive Organs

Ducts, glands, and external genitalia. Reproductive system structures apart from gonads.

Testes

Primary reproductive organ in the male. Have both an exocrine function and an endocrine function. The male gonads, which produce sperm and secrete male sex hormones.

Scrotum

A divided sac of skin. The external pouch that contains the testes and controls temperature.

Seminiferous Tubules

"Sperm-forming factories" Small convoluted tubules in the testes where spermatogenesis takes place.

Myoid Cells

Muscle like cells in basement membrane of seminiferous tubules that contract midly to help move sperm & fluid through tubules.

Leydig Cells (interstitial cells)

Produce testosterone.

Penis

Is designed to deliver sperm into the female reproductive tract.

Glans Penis

The enlarged tip of the penis.

Prepuce

A fold of skin covering the tip of the penis.

Corpus Spongiosum

The mass of spongy tissue surrounding the male urethra within the penis.

Corpus Cavernosa

Two columns of erectile tissue in the shaft of the penis that rush with blood for erection.

Accessory Ducts

Are the seminal vesicles, prostate gland, and the bulbourethral glands. These glands secrete fluids that enter the urethra.

Epididymis

A highly coiled comma-shaped tube that caps the superior part of the testis. First part of the male duct system that provides a temporary storage site for the immature sperm.

Ductus Deferens

A duct that carries sperm from the epididymis to the ejaculatory duct. Main function is to propel live sperm from their storage sites.

Ejaculatory Duct

Passes through the prostate gland to merge with the urethra.

Vasectomy

Surgical procedure that removes all or part of the vas deferens (usually as a means of sterilization).

Urethra

Extends from the base of the urinary bladder to the tip of the penis, is the terminal part of the male duct system. Three regions: Prostatic, Membranous, and Spongy. Carries both urine and sperm to the body exterior.

Seminal Vesicle (Gland)

Located at the base of the bladder. Produce about 60% of the fluid volume of semen. Nourish and activate the sperm passing through the tract.

Prostate

Size and shape of a chestnut. Secretion of a milky fluid that plays a role in activating sperm.

Bulbourethral Gland

Are tiny, pea-sized glands. They produce a thick, clear mucus that neutralizes urinary acids and lubricates the glans penis.

Semen

A milky white, somewhat sticky mixture of sperm and accessory gland secretions. The liquid provides a transport medium and nutrients and contains chemicals that protect the sperm and aid their movement.
