  1. Reproductive Systems

  2. Male Anatomy Penis: • Allows passage of urine and semen • Has many nerve endings to provide sensation Scrotum: • Muscular sac which is shorter when cold, longer when warm • Holds testes • Controls temperature • Provides sensation

  3. Testes: • Produce sperm and sex hormones • Each is made of 500-1200 feet2 of tightly coiled tubes Epididymis: • Sight of sperm maturation Vas deferens: • Stores sperm • Allow passage of sperm • Big around as sewing thread

  4. Seminal Vesicles: • Contributes sugar to semen for nourishing the sperm Semen: • Helps sperm live longer and travel better • Roughly teaspoon per ejaculation Prostate Gland: • Produces most of the liquid that makes up semen

  5. Cowper’s Glands (aka bulbourethral glands): • Produce fluid called pre-ejaculate that cleanses the urethra of acid (from urine) to protect the sperm

  6. Female Anatomy Uterus: • Houses and protects baby • Allows nutrient & waste exchange with placenta • Nourishes embryo before the placenta grows Cervix: • Bottom section of the uterus • Produces fluids to help sperm travel • Produces a mucous plug to keep germs out during pregnancy

  7. Vagina: • Allows passage of sperm, shed endometrial lining, and a baby • Produces fluids to help cleanse and lubricate itself and to help sperm travel • A flexible, stretchy tube Hymen: • Membrane covering vaginal opening

  8. Ova: • Eggs Ovaries: • Store eggs Fallopian Tubes: • Passage way from ovaries to uterus Vulva: • Protect opening of urethra and vagina, like eyelids protect eyes • Made up of labia majora, labia minora, and clitoris
