• Produce reproductive cells
• Reproductive cells
• Carry the sperm from testis to urethra

  Ductus or vans deferens
• The male sex hormone is called testosterone
• Semen is produced by seminal vesicles, prostate gland, bulbourethral glands
• Female Reproduction System
• Ejaculation is when semen leaves the penis during sexual intercourse
• Ovaries are where eggs produce
• Uterus is where fertilization occurs and fetal development takes place
• Fallopian tube are where eggs develop and mature
• Cervix connects uterus with vagina
• Cervix is the lower part of uterus that opens into vagina
• Vagina is birth canal, stores sperm, and receives penis during sex
• Menstruation is shedding of endometrium lining if no pregnancy has occurred
• Semen is made up of sperm cells and fluid from prostate gland, seminal vesicles, bulbourethral glands, and Cowper's glands.
• Bulbourethral glands secrete mucous to lubricate urethra
• Ejaculation is release of semen through urethra
• Vas deferens


  Transports mature sperm to the
• Testis


  Responsible for making testosterone and producing sperm cells
• Prostate gland


  A walnut-like structure which contributes additional fluid to the ejaculate, and help to nourish the sperm
• Seminal Vesicle


  Produces a sugar-rich fluid (fructose) that provides sperms with a source of energy and helps with the sperms motility
• Scrotum


  Hangs behind the penis and contains the testicles. It acts as a climate control system for the testes
• Cowper's gland


  Also called the Bulbourethral gland, it produces a clear, slippery fluid that empties directly into the urethra. This fluid serves to lubricate the urethra and to neutralize any acidity due to residual drops of urine in the urethra
• Urethra


  Carries urine from the bladder to outside of the body
• Epididymis


  A long, coiled tube that rests on the backside of each testicle. It carries, stores, and brings the sperm to maturity
• Ejaculatory duct


  Urethra in preparation for ejaculation formed by the fusion of the vas deferens and the seminal vesicles
• Penis


  Deposits the sperm into the vagina during mating
• Ovary


  • Site of oogenesis
  • Produces hormones estrogen and progesterone
• Endometrium


  Nourishes the embryo, sheds during menstruation
• Ovaries contain 400,000 egg cells
• Vagina


  Entrance of the penis, also called the birth canal
• Fimbriae


  Picks up the ovum from the ovary
• Ovaries alternate each month to produce an egg/ovum
• Fallopian tube (oviduct)


  Passage from ovary to uterus, site of fertilization
• Only 400 actually mature between the ages of 12-50
• Cervix


  The lower, narrow end of the uterus (womb) that connects the uterus to the vagina (birth canal)
• Females have 2 ovaries
• Uterus


  Site of egg implantation, embryo development
• Ovary


  Site of oogenesis, produces hormones estrogen and progesterone
• Estradiol


  Instrumental in breast development, fat distribution in the hips, legs and breasts, and the development of reproductive organs secreted by ovaries PRIOR to ovulation
