SCIENCE QUARTER 3(MALE REPRODUCTIVE SYSTEM)

• Male Reproductive System

  -regulated by hormones ,primarily testosterone

  -ensure the production ,maturation, and delivery of sperm for reproduction

  -continue to the development of male sexual characteristics

  -2 major functions (to reproduce and urination)
• Functions of Male Reproductive System

  -production and delivery of sperm for fertilization

  -responsible for delivering sperm to the female reproductive tract during sexual intercourse

  -ensure the production ,maturation ,fertilization of an egg and contribute to the continuation of the species
• Scrotum

  -protects your testicles

  -provide a sort of "climate control"
• Testicles

  -produce testosterone and sperm
• Sperm

  -male reproductive cell or gamete

  -produced in a process called spermatogenesis
• Epididymis

  -long coiled tube on the back of each testicles

  -stores sperm cells(mature sperms)
• Pubic Bone

  -most forward-facing bone of the pelvic bone that protects urinary organs and internal sex organs
• Rectum

  -end of the large intestine ,a continuation of the sigmoid colon and connects to the anus
• Penis

  -external organ used to urinate , sex, and reproduction
• Vas Deferens

  -long muscular tube that transports mature sperms
• Seminal Vesicles

  -sac likes pouches and it make 80% of your ejaculatory including fructose

  -provide liquid
• Fructose

  -energy source for sperm
• Ejaculatory Ducts

  -where they collect fluid to add semen
• Prostate Gland

  -walnut sized ,adds additional fluid to ejaculate and helps nourish the sperm

  -gives nutrition to the sperm (white color)
• Bulbourethral Gland

  -pea sized structured, creates a clear ,slippery fluid that empties directly into the urethra

  -act as a mop to sweep away remaining urine in a urethra of a boy
• Urethra

  -carries pee or ejaculates sperm
• Hormones

  -signaling molecules produced by endocrine glands

  -crucial for regulating various physiological processes
• Follicle Stimulating Hormone

  -stimulates sertoli cells in the testes supporting the development and maturation of sperm cells
• Luteinizing Hormone

  -necessary to continue the process of spermatogenesis by stimulating leydig cells to produce testosterone
• Testosterone

  -main sex hormone in men

  -support sperm production , contributes to the development pf secondary sexual characteristics ,maintains bone density and muscle mass , influences libido , sexual function and plays a role in mood , energy and metabolism

  -produce by testes
