    Study Notes

    Hormones in Human Reproduction

    • Male Hormone: Testosterone is critical for sperm development
    • Female Hormones:
      • Estrogen: Critical for follicle development
      • Progesterone: Sustains pregnancy and inhibits new follicle development
    • Hormones in Childbirth and Lactation:
      • Relaxin: Causes ligaments around the birth canal to relax
      • Oxytocin: Causes milk letdown

    Male Reproductive System

    • Testicles are the site of sperm production and testosterone synthesis
    • Sperm contain half of the genetic makeup
    • Epididymis is responsible for sperm storage and maturation
    • Scrotum protects the testes and regulates temperature to facilitate sperm development

    • Sperm contain half of the genetic makeup
    • Epididymis is responsible for sperm storage and maturation
    • Scrotum protects the testes and regulates temperature to facilitate sperm development

    Male Reproductive System

    • The testicles are responsible for producing sperm and synthesizing testosterone.
    • Sperm cells contain half of the genetic makeup, contributing to the offspring's genetic traits.
    • The epididymis stores and matures sperm, preparing them for fertilization.
    • The scrotum serves as a protective sac for the testes, regulating temperature to ensure optimal sperm development.
    • The vas deferens acts as a transport tube, carrying sperm from the epididymis to the urethra.
    • The urethra is a shared passageway for both sperm and urine, allowing for the elimination of waste and the release of sperm during ejaculation.
    • The penis is the organ of copulation, facilitating sexual intercourse and reproduction.

    Female Reproductive System

    • Ovaries are responsible for producing eggs, which contain half of the genetic makeup necessary for fertilization.
    • The site of fertilization is the oviducts, where the sperm meets the egg.
    • The oviducts also function as a transportation pathway, moving the fertilized embryos to the uterus.
    • The uterus is the site where embryonic development takes place during gestation.

    Female Reproductive System

    • The cervix connects the uterus and vagina, serving as a barrier during pregnancy.
    • The vagina is the female organ of copulation during mating and is also the opening of the bladder.
    • The vulva is the external opening of the reproductive system.
