  1. The Male Reproductive System

  2. Penis http://kidshealth.org/misc/movie/bodybasics/male_repro.html Male organ used in reproduction Two parts are shaft and glands Delivers sperm and urine through the urethra

  3. Scrotum http://www.malecontraceptives.org/methods/images/heat.jpg Sac-like structure that holds the testicles and the epididymises It is used to monitor and control the temperature of the testicles so sperm can be produced Scrotum maintains a temperature 2-3 degrees lower than body temperature

  4. Testicles http://www.malecontraceptives.org/methods/images/heat.jpg Small oval organs held by the scrotum that make/produce testosterone and sperm Part of the endocrine system Must maintain 2-3 degrees lower than body temperature to produce sperm

  5. Sperm http://www.babble.com/CS/blogs/strollerderby/sperm%2001.jpg Is the male gamete Consists of a head, a mid-piece, and a tail Nucleus lies in the head along with chromatin and genetic information Is a haploid cell and when joined with the haploid egg cell becomes a diploid

  6. Testosterone http://itech.dickinson.edu/chemistry/wp-content/uploads/2008/04/testosterone.jpg Main hormone produced in a male’s body Kick-starts the making of sperm Takes a major part in puberty Causes male to develop a deeper voice, leaner and larger muscles, and more hair Considered to be an anabolic steroid

  7. Epididymis http://wikipedia.org/#epididymis Epididymis: a set of twisting ducts (tubes) that connects to the vas deferens Where sperm are stored Sperm mature in the epididymis Serves as a pathway from the testicles to the vas deferens for sperm

  8. Vas deferens Vas deferens: transports sperm to the urethra in expectation of ejaculation Contractions in the vas deferens propel the sperm onward http://wikipedia.org/#epididymis

  9. Semen and Seminal fluid Semen: The fluid that carries sperm and seminal fluid Seminal fluid: made in the prostate gland and the seminal vesicles Nourishes sperm and carries it outside the penis during ejaculation http://spermomax.net/sperm.jpg

  10. Prostate gland Produces parts of semen Contains smooth muscles that help force out sperm during ejaculation To work, the prostate gland need hormones http://en.wikipedia.org/wiki/Prostate

  11. Seminal vesicles Sac-like accessory gland Attaches to the side of the vas deferens Produces parts of semen http://en.wikipedia.org/wiki/Seminal_vesicle

  12. Urethra Tube-like structure which connects the bladder of an organism to the outside of its body Passageway for semen Passageway for urine http://www.malecontraceptives.org/methods/images/vas_urethra.gif

  13. Pituitary Gland Located near the brain Triggers the production of testosterone in males using hormones Controls the other endocrine system glands http://www.gynaeonline.com/images/pituitary_gland.gif
