Ch. 8 Reproductive System Notes

Chapter 8: Reproductive Function
Anatomy and Physiology
Normal Male Reproductive System
 Steps of sperm to exit the body
o Starts in the seminiferous tubules
 Spermatogenesis occurs (creates more sperm)
o Epididymides
 Where sperm is stored
o Sperm then moves through the:
 Vas deferens (a duct / tube)
 Seminal vesicles

 Prostate gland
 Increases sperm motility
 Prolongs sperm life
 Decreases the ejaculatory fluid’s acidity mixing with the semen to create an alkaline medium that
counteracts the acidity of the vaginal secretions
o Sperm then moves through the urethra where the Cowper’s glands are located
 They secrete another alkaline fluid into the urethra to neutralize acidity caused by urine transportation
 Steps of an Erection
o Blood vessels dilate
o Build-up of fluid in the corpus cavernosa
 Penis
o Consists of three cylinders
 Corpus spongiosum
 Two corpus cavernosa
 Scrotum
o Contains the testes, epididymides, and lower spermatic cords
o Maintains testicular temperature
 Testes (gonads)
o Produce sperm and the sex hormones
o Secretes testosterone in their Leydig cells
 Duct System
o Includes the epididymis, vas deferens, spermatic cord, ejaculatory duct, and urethra
o Once they mature, sperm leave the epididymis and travel to the vas deferens
 Accessory Glands
o Prostate gland  secretes fluid that mixes with the sperm and secretions of the seminal vesicles
o Cowper’s gland  two pea-sized glands that secrete another alkaline fluid (precum)
Normal Female Reproductive System
 Ovaries
o Where oogenesis occurs
 More eggs are made
o Secretes estrogen and progesterone
o After puberty (mature), about 400,000 eggs are made
o Follicle Stimulating Hormone (FSH)
 Stimulates the production of the sperm and the egg
o Luteinizing Hormone (LH)
 Stimulates the secretion of testosterone and estrogen
 Stimulates ovulation
o Ovaries releases an egg or eggs every 28 days
o Scar forms from the released egg; this is called corpus luteum
 Corpus luteum secretes progesterone
 Fallopian Tubes
o Moves the ovum towards the uterus and assists sperm in moving from the uterus towards the ovum that is likely still
in one of the tubes
o The most common site for ectopic pregnancy
Released by the anterior
pituitary gland
