Male reproductive System

• Spermatogenesis is the process by which human sperm cells are produced in the seminiferous tubules of the testes.
• Scrotum It consist of skin, Beneath a skin are loose connective tissues and a layer of smooth muscle called Dartos
• Testes are oval organs whitin a scrotum 4-5 cm long; which sperm cell developed
• Testes produced androgens example is Testosterone
• Testes Leydig Cells ( interstitial cells)
• Epididymis is a coiled tube that lies on top of the testes
• Vas deference emerges from the epididymis and ascends along the posterior side of testes
• Seminal vesicle a pair of glands that secrete a liquid of component of semen into vas deference
• Secretion is alkaline contains fructose, ascorbic Acid, coangulating enzyme, and prostaglandin
• Bulbo-urethral gland is also known as Cowper's gland
• Prostate Gland is located below bladder and surrounds urethra
• Bulbourethral gland acts to wash residual urine out of the urethra when ejaculating semen
• Ejaculation is the process by which semen is expelled through penis during sexual intercourse or masturbation
• Semen is made up of spermatozoa and secretions from accessory sex organs
• Testes are oval shaped structures found within scrotum
• The male reproductive system consists of external genitalia (penis) and internal genitalia (testes)
• The male genitalia include the penis, scrotum, testes, epididymis, vas deferens, prostate gland, bulbourethral glands, and seminal vesicles.
• The male genitalia are involved in reproduction and excretion.
• Urethra is a tube that transports both urine and semen
• penis function is to transfer sperm cell to Vagina
• Penis external sructures Glans Penis, Prepuce(foreskin)
• Male Ejaculatesabout 2-5 ml of semen; each millimeter containing about 50-130 million sperms
• Sertoli nurse help to promote spermatogenesis
