Human Reproductive System

  • Responsible for the continuation of human life.

  • Involved in reproduction processes.

Functions of Male Reproductive System

  • Main Functions:

    1. Produce, maintain, and transport sperm and semen.

    2. Discharge sperm into the female reproductive tract.

    3. Produce and secrete male sex hormones.

Parts of the Male Reproductive System

  • Testis (Testicles):

    • Oval organs (4-5 cm in length) located within the scrotum.

    • Comprised of lobules containing seminiferous tubules.

    • Production of sperm cells occurs here.

  • Scrotum:

    • Controls temperature of testicles and protects them.

  • Epididymis:

    • A coiled tube storing sperm and transporting it from the testes.

  • Vas Deferens:

    • Sperm duct that carries sperm from the testes to the urethra.

  • Prostate Gland and Seminal Vesicles:

    • Secretes fluids that support sperm function and assist in semen formation.

  • Bulbourethral Glands (Cowper’s Gland):

    • Secretes glycoproteins for lubrication during sexual activity.

  • Ejaculatory Duct:

    • Joins the vas deferens and urethra, delivering sperm during ejaculation.

  • Penis:

    • Delivers sperm into the vagina and expels urine. Contains urethra.

Male Secondary Sex Characteristics

  • Physical changes observed during puberty include:

    • Growth of beard and body hair.

    • Changes in body form and muscle development.

    • Lowered voice pitch and increased facial hair.

Hormones of the Reproductive System

  • Hormones are body's chemical messengers, secreted by endocrine glands.

  • The testes produce testosterone:

    • Drives physical changes in males during puberty.

    • Maintains muscle mass, bone mass, sperm production, and sex drive throughout life.

Conclusion

  • Overall connections between parts and functions of the male reproductive system, as well as hormonal influences.
