    Seminal Vesicles

    Paired glands that produce fluid rich in fructose, contributing to most of the semen volume.

    Prostate Gland

    Accessory male reproductive organ at the base of the bladder, producing secretions with zinc and enzymes for sperm health.

    Ejaculatory Ducts

    Passages that carry semen, mixing it with prostatic secretions.

    Testes

    Paired organs responsible for sperm production.

    Study Notes

    Male Reproductive Tract Components

    • The male reproductive tract includes paired testes, epididymis, vas deferens, seminal vesicles, ejaculatory ducts, and prostate.
    • These components work together to produce, transport, and deliver sperm to the female reproductive tract for reproduction.

    Seminal Vesicles

    • Paired accessory sex glands.
    • Produce a fluid rich in fructose, contributing 50-80% of semen volume.

    Prostate Gland

    • An accessory male reproductive organ located at the base of the bladder, surrounding the urethra.
    • Produces prostatic secretions containing zinc, citric acid, calcium, phosphates, and other enzymes.
    • These secretions are essential for sperm health and motility.
    • Semen mixes with the prostatic secretions during ejaculation.
