Internal Male Reproduction System

• Scrotum - protective sac of skin, where testes are located
• testes - produce sperm and testosterone, located in scrotum. The primary male reproduction organ.
• • seminiferous tubules - tiny coiled tubes in the testes where sperm are produced
• rete testis - connects the Seminiferous Tubules to the Efferent Ducts
• efferent ducts - connects the Rete Testis to the initial section of the Epididymis
• Epididymis - where maturation of sperm happens, where most sperm are stored
• vas deferens - also called “ductus deferens” transports sperm cells from the Epididymis to the Ejaculatory Duct
• seminal vesicle - produces fluid rich in sugar that nourishes sperm and helps it move
• ejaculatory duct - tube that is formed by the union of the ends at Vas Deferens and Seminal Vesicle
• Prostate Gland - secretes the sperm alkaline fluid that neutralizes the acids in the female reproductive system
• bulbourethral Gland - “Cowpers Gland” produces alkaline fluid that neutralizes traces of acids in the male urethra secretes “semen”
• • Urethra - passageway of the sperm and urine
• penis - erectile tissue, erects penis, ejaculates semen
• Erectile Tissue - stiffens the penis uses blood
• Prepuce ( Foreskin ) - the skin of the head of the penis removed during circumcision
• Glans of the Penis - sensitive part of the penis
• Ureter - carries urine to the kidney
• Urinary Bladder - stores urine
• Testosterone - responsible for the secondary male characteristics
• Luteinizing Hormone - stimulates the Leydig Cells for the secretion of the sec hormone “Testosterone”
• Follicle-stimulating hormone - stimulates the cells in the testis in the production of sperm ( spermatogenesis )
• Ejaculation - forceful expulsion of the sperm out pf the male’s body
• Head - made up of a nucleus covered by a cap called “acrosomes”, stores enzyme that is needed to penetrate the egg cell
• Mid Piece - contains the mitochondria, supplies the energy needed by the sperm through the female reproductive system
• Tail - a powerful flagellum that whips back and forth, allows the sperm to move
