Male and Female Reproductive System Quiz

Male Reproductive System

• Produces sperm and releases testosterone
• Consists of:
• Testes: produces sperm cells
• Scrotum: sac of skin that holds the testes
• Penis: deposits sperm into the vagina during mating
• Vas Deferens: carries sperm from testes to urethra
• Urethra: carries sperm and urine out of the body
• Glands:
  • Seminal Vesicle: secretes fluid that makes up most of semen
  • Prostate Gland: secretes slightly alkaline milky fluid as part of semen
  • Bulbourethral Gland: secretes thick clear mucus to lubricate and neutralize acidic urine in urethra

Female Reproductive System

• Functions:
• Releases egg cells
• Produces progesterone and estrogen
• Provides environment for fertilized egg to develop during pregnancy
• Facilitates labor and childbirth
• Consists of:
• Ovary: produces egg cells
• Oviduct: serves as passageway for eggs from ovary to uterus, site of egg fertilization
• Uterus: serves as site of egg implantation, where fertilized egg develops
• Vagina: receives penis during mating

Puberty

• Begins when a child's body starts to develop and change as they become an adult
• In girls: develop breasts and start their periods
• In boys: develop deeper voice and facial hair starts to appear

Hormones in Reproductive Systems

• Pituitary Gland:
• Controls function of testes and ovaries
• Regulates production of sperm cells and release of semen in males
• Regulates growth and release of eggs from ovaries in females
• Hormones:
• Travel in bloodstream to tissues or organs
• Work slowly, affecting growth and development, metabolism, sexual function, reproduction, and mood
• Hypothalamus and Pituitary Glands:
• Controls function of testes and ovaries
• Keeps reproductive system properly functioning
• Gonadotropin-Releasing Hormone (GNRH):
• Released from nerve cells in the brain
• Controls production of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from pituitary gland
• Luteinizing Hormone (LH):
• In women: helps control menstrual cycle, triggers release of egg from ovary
• In men: assists in spermatogenesis, initiates production of testosterone in testes
• Follicle-Stimulating Hormone (FSH):
• In women: stimulates growth of ovarian follicles before ovulation, increases estradiol production
• In men: helps control production of sperm

Male Hormones

• Androgens: steroid secreted by testes, responsible for maintenance and behavior
• Testosterone:
• Responsible for male sexual secondary characteristics
• Induces spermatogenesis
• Strengthens voice, develops facial, axillary, and pubic hair, begins sex drive

Female Hormones

• Estrogen:
• Helps in endometrial growth, ovulation, and calcium absorption
• Responsible for female secondary sexual characteristics, including breast development, flared hips, and faster bone maturation
• Progesterone:
• Helps with endometrial re-growth, inhibits release of FSH and LH
