GEN BIO L3 FINALS

• Male reproductive system

  • located outside of his body
• External parts

  • penis
  • scrotum
  • testicles
• Sperm cells

  • a form of gamete or reproductive cell
• Semen

  • the protective fluid around sperm
• the entire male reproductive system depends on "hormones"
• Hormones

  • are chemical that stimulate or regulate activity in your cells or organ
• Follicle-Stimulating Hormone

  • is necessary to produce sperm (spermatogenes)
• Your pituary gland makes FSH
• Luteinizing Hormone (LH)

  • ssary to continue the process of spermatogenesis
  • is important for making sperm
• Testosterone

  • it helps you to develop certain characteristics
  • incluing muscle mass, and strength, fats distribution, bone mass and sex drive (Libido)
• Estrogen

  • regulating the mestrual cycle
  • important sex hormone produced by the ovaris in female and testes in male
• Progesterone

  • is to prepare the endometrium (lining of your uterus) for a fertilized egg to implant and grow
• Dihydrotestosterone

  • is a hormone and androgen that plays a key role in the sexual development of people assigned male at birth
  • plays a vital role in the sexual development of males
• Penis

  • male organ for sexual intercourse
  • it contains many sensitive nerves ending and it has three parts
• Root

  • the - is the base of your penis.
  • it attaches to the wall of your abdomen
• Glans

  • the - is the cone-shaped tip of the penis
• Foreskin

  • loose layer of skin
• Circumcision

  • surgically remove the foreskin
• Body (Shaft)

  • the main part of the penis and glans is th tip
  • all end of the glans is a small slit or opening, ehich is where semen and oee exit body through the urethra
• The inside of the penis is made of spongy tissue that can expand and contract
• Testicle

  • loose-pouch like sac of skin that hangs behind the penis
  • it contains the testicles (all called testes) as well as many nerve and blood vessels
  • makes testosterone and produce sperm
• testicles are coiled of masses tubes called seminiferous tubules
• the seminiferous tubules produce sperm cells called spermatogenesis
• Epididymis

  • coiled tube that rests on the backside of each testicles
  • it functions in the carrying and storage of the sperm cells that are produced in the testes
  • it also is the job ig the epididymis to bring sperm to maturity
• Vas deferens

  • long muscular tube that travels from the epididymis into the pelvic cavity to just behind the blader
  • transport mature sperm to urethra in preparation of ejaculation
• Ejaculatory Duct

  • each testicle has a vas deferens that joint with the seminal vesicle to form -
  • move through your prostate, where they collect fluid to add to semen
  • they empty into your urethra
• Urethra

  • is the tube that carries pee from your bladder outside your body
  • it also ejaculates semen when you reach orgasm
• Seminal Vesicle

  • sac-like pouches that attah to the vas deferens
  • produce sugar -rich fluid that provides sperm with a source of energy and helps with the sperms motility (ability to walk)
  • the fluid makes up of the volume of a man's ejaculatory fluid, or ejaculate
• Prostate Glands

  • walnut-size structure that is licated below the urinary bladder in front of the rectum
  • also help sperm to nourish the sperm
• Bulbourethral (Cowper) Glands

  • are pea-sized structures on the sides of your urethra just below your prostate
  • the create a clear slippery fluid that empties drectly into the urethra
  • this fluid lubricates the urethra and neutralizes and acids that may remain from your pee
• Prostitis

  • involves swelling or inflammation of the prostte gland and can cause or difficulty urination or ejaculation
• Prostate Cancer

  • develops in the prostate a small wal-nut shaped gland located below the bladder and in front of the rectum in men
• Sexually Transmitted Infection

  • is a serious condition that can develop after you have sex
• Male Infertility

  • can be caused by low sperm production, abnormal sperm function or blockage that prevent the delivery of sperm
• Testicle Cancer

  • start when something causes, changes to the DNA of testicle cells
