Male Reproductive System

• Reproductive System is the biological system made up of all anatomical organs involved in sexual reproduction.
• Anatomy of a Male Reproductive System:

  Bladder

  Vas deferens

  Urethra

  Penis

  Glans

  Prepuce (Foreskin)

  Rectum

  Seminal Vesicle

  Ejaculatory duct

  Prostate Gland

  Cowper's gland

  Epididymis

  Testis

  Scrotum
• The scrotum regulates the temperature of the testes.
• Sperms form best at 35°C.
• External Structure of The Male Reproductive System:

  Penis

  Scrotum

  Testis

  Epididymis
• Penis deposits the sperm into the vagina during mating
• Scrotum hangs behind the penis and contains the testicle. It acts as a climate control system for the testes.
• Testis is responsible for making testosterone and producing sperm cells.
• Epididymis is a long, coiled tube that rests on the backside of each testicle. It carries, stores, and brings the sperm to maturity.
• Vas deferens transports mature sperm to the urethra in preparation for ejaculation.
• Ejaculatory duct is formed by the fusion of the vas deferens and the seminal vesicles.
• Urethra carriers urine from the bladder to outside of the body.
• Seminal Vesicles produces sugar- rich in fluid (fructose) that provides sperms with a source of energy and helps with the sperms' motility (ability to move).
• Prostate Gland is a walnut-like structure which contributes additional fluid to the ejaculate, and help to nourish the sperm.
• Cowper's Gland also called the Bulbourethral Gland, and produces a clear, slippery fluid that empties directly into the urethra.
• Pituitary Gland in the brain
• (FSH) Follicle-Stimulating Hormone signals sperm production (spermatogenesis).
• (LH) Luteinizing Hormone stimulates production of testosterone.
• Testosterone is the most important male hormone.
• Testosterone is responsible for regulating sex, differentiation, male sex characteristics, spermatogenesis, and fertility.
• Internal Structures of The Male Reproductive System:

  Vas deferens

  Ejaculatory duct

  Urethra

  Seminal Vesicles

  Prostate Gland

  Cowper's Gland
• The Vas deferens is also called the vasectomy
