    Study Notes

    Male Reproductive System

    • Leydig cells in the testes secrete testosterone.
    • Meiosis in the gonads produces gametes (sperm or ova) with a unique combination of chromosomes.
    • The final stage of spermatogenesis is the formation of mature sperm.
    • The function of mature sperm is to fertilize an egg cell.
    • The hormone that initiates spermatogenesis is follicle-stimulating hormone (FSH).
    • The vas deferens stores sperm and propels them toward the urethra during ejaculation.
    • The male reproductive system includes the testes, epididymis, vas deferens, seminal vesicles, prostate gland, urethra, and penis.

    Scrotum and Temperature Regulation

    • The function of the scrotum is to regulate the temperature of the testes, which is essential for spermatogenesis.
    • The temperature of the testes is regulated by the scrotum, which can move closer to or farther from the body to maintain a cooler temperature than the rest of the body.

    Sertoli Cells and Seminal Vesicles

    • Sertoli cells in the testes provide support and nourishment to developing sperm cells.
    • The seminal vesicles and prostate gland produce fluids that make up semen, which nourishes and transports sperm during ejaculation.

    Female Reproductive System

    • Sperm cells are made in the testes, but egg cells are made in the ovaries.
    • The vagina is the external genitalia of the female, and its function is to receive sperm during sexual intercourse.
    • The term for the external genitalia of the female is the vulva.
    • The main function of the mammary glands is to produce milk for nursing infants.

    Hormones

    • Inhibin inhibits the secretion of FSH and GnRH.
    • Estrogens are hormones produced by the ovaries that stimulate female secondary sex characteristics and regulate the menstrual cycle.
    • The main function of progesterone is to prepare the uterus for implantation of a fertilized egg.

    Menstrual Cycle

    • During the luteal phase of the menstrual cycle, the corpus luteum secretes estrogens and progesterone.
    • If fertilization and implantation do not occur, the corpus luteum degenerates.
    • The surge of luteinizing hormone (LH) triggers ovulation in a 28-day menstrual cycle.
    • During pregnancy, the corpus luteum continues to produce progesterone to maintain the pregnancy.
    • Oral contraceptives prevent ovulation by inhibiting the surge of LH.
    • The postovulatory phase is also known as the luteal phase.

    Other Reproductive Structures

    • The inguinal canal is a passageway for the spermatic cord in males.
    • The ejaculatory ducts connect the seminal vesicles and vas deferens.
    • The male urethra is used for both urination and ejaculation.
    • The main function of the seminal vesicles is to produce fluids that make up semen.
    • The main function of the prostate gland is to produce fluids that make up semen.
    • The main function of the bulbourethral (Cowper's) glands is to produce fluids that make up semen.
