Female Reproductive System:

The female reproductive system is comprised of both internal and external reproductive organs that both enable fertilization and support embryonic development. Structures of the female reproductive system include:
Labia majora: Larger lip-like external structures that cover and protect other reproductive structures.
Labia minora: Smaller lip-like external structures found inside the labia majora. They provide protection to the clitoris, urethra, and vaginal openings.
Clitoris: Sensitive sexual organ located in the uppermost section of the vaginal opening. The clitoris contains thousands of sensory nerve endings that respond to sexual stimulation and promote vaginal lubrication.
Vagina: Fibrous, muscular canal leading from the cervix to the external portion of the genital canal. The penis enters the vagina during sexual intercourse.
Cervix: Opening of the uterus. This strong, narrow structure expands to allow sperm to flow from the vagina into the uterus.
Uterus: Internal organ that houses and nurtures female gametes after fertilization, commonly called the womb. A placenta, which encases a growing embryo, develops and attaches itself to the uterine wall during pregnancy. An umbilical cord stretches from the fetus to its placenta to provide nutrients from a mother to an unborn baby.
Fallopian tubes: Uterine tubes that transport egg cells from the ovaries to the uterus. Fertile eggs are released from ovaries into fallopian tubes during ovulation and typically fertilized from there.
Ovaries: Primary reproductive structures that produce female gametes (eggs) and sex hormones. There is one ovary on either side of the uterus.
Male Reproductive System:

The male reproductive system consists of sexual organs, accessory glands, and a series of duct systems that provide a pathway for sperm cells to exit the body and fertilize an egg. Male genitalia only equips an organism to initiate fertilization and does not support the development of a growing fetus. Male sex organs include:
Penis: The main organ involved in sexual intercourse. This organ is composed of erectile tissue, connective tissue, and skin. The urethra stretches the length of the penis and allows either urine or sperm to pass through its external opening.
Testes: Male primary reproductive structures that produce male gametes (sperm) and sex hormones. Testes are also called testicles.
Scrotum: External pouch of skin that contains the testes. Because the scrotum is located outside of the abdomen, it can reach temperatures that are lower than that of internal body structures. Lower temperatures are necessary for proper sperm development.
Epididymis: System of ducts that receive immature sperm from the testes. The epididymis functions to develop immature sperm and house mature sperm.
Ductus Deferens or Vas Deferens: Fibrous, muscular tubes that are continuous with the epididymis and provide a pathway for sperm to travel from the epididymis to the urethra
Urethra: Tube that extends from the urinary bladder through the penis. This canal allows for the excretion of reproductive fluids (semen) and urine from the body. Sphincters prevent urine from entering the urethra while semen is passing through.
Seminal Vesicles: Glands that produce fluid to nurture and provide energy to sperm cells. Tubes leading from the seminal vesicles join the ductus deferens to form the ejaculatory duct.
Ejaculatory Duct: Duct formed from the union of the ductus deferens and seminal vesicles. Each ejaculatory duct empties into the urethra.
Prostate Gland: Gland that produces a milky, alkaline fluid that increases sperm motility. The contents of the prostate empty into the urethra.
Bulbourethral or Cowper's Glands: Small glands located at the base of the penis. In response to sexual stimulation, these glands secrete an alkaline fluid which helps to neutralize acidity from the vagina and urine in the urethra.
