Study Notes
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
