    A male sex cell, a male gamete
  2. Coitus or copulation
    Sexual intercourse
  3. What r fraternal twins?
    Twins resulting from the fertiliation of seperate ova by seperate sperm cells. Hereditary.
  4. Identical twins?
    identical twins result from fertilization of a single egg cell by a single sperm. Always the same sex, and very familiar in form and features.
  5. Testosterone
    Male reproductive system secretes this hormone. responsible for production of the male characterstics (hair, deep voice, etc)
  6. gonads a.k.a.
    testicles, testes or testis (singular)
  7. Spermatogenesis develops where?
    in the scrotum, a sac enclosing the testes.
  8. What is seminiferous tubules?
    The interior of a testis is composed of a large mass of narrow, coiled tubules. These tubules contain cells that manufacture spermatozoa.
  9. After formation, cperm cells mover through the sminiferous tubules and collect in ducts that lead to a larfe tube, the __________.
    epididymus (which is located at the upper part of each testis.
  10. From the epididymis to the ductus deferens a.k.a. ____________.
    vas deferns. The vas deferens is about 2 feet long and carries the sperm to the pelvic region.
  11. During a vasectomy or sterilization procedure, the urologist cuts and ties of each ___________.
    vas deferens.
  12. The seminal vesicle is at the level of the urinary bladder to for the _________ duct.
    Ejaculatory duct, leading toward the urethra.
  13. a thick, sugary, yellowish substance that nourishes the sperm cells and forms much of the volume of ejactulation is _________.
    Semen
  14. What is Cryptorchism?
    Where the testes do not descend, but can be corrected by surgery.
  15. Parenchymal tissue
    Tissue that carries on the main function of an organ. In the male, the parenchymal tissue is the sminiferous tubules.
  16. Interstitial tissue
    Tissue that produces testosterone, which is responsible for secondary sex characteristics.
  17. Stroma or stromal tissue
    Is supportive tissue
  18. There are three internal glands:
    1. seminal vesicles- secretes a fluid to nourish the sperm cells
    2. prostate gland- aids in the motility of sperm by secreting a fluid that is alkaline
    3. Cowper's gland, which is also known as ________________.
    bulbourethral gland, it secretes fluid that lbricates and neutralizes the urethra for safe passage.
  19. glans penis
    head of the penis, slightly larger than the main body of the penis.
  20. The penis is covered with a fold of soft flexible skin called foreskin or __________.
    Prepuce. Circumcision removes the foreskin from around the glans.
  21. impotence
    inability to achieve an erection. Viagra (sildenafil citrate) is a drug that increases blood flow to the penis, enhancing that ability to have an erection.
  22. phimosis
    a narrowing of the opening of the foreskin over the glans can interfere with urination and cause infection. Treatment is circucision.
  23. hypospadia
    sometimes at birth the opening of the urethra is found on the lover surface of the penis
  24. epispadia
    the opening of the urethra is found on the upper surface of the penis
  25. Know the following order which traces the path of spermatozoa from their formation in the seminiferous tubules of the testes to the outside of the body.
    Seminiferous tubules (testes, sperm formed here) --> Epididymis --> Vas deferens (siminal vesicles) --> Ejaculatory duct --> Urethra (prostate gland->cowper glands) --> penis --> leaves body
  26. flagellum
    hair like projection on a sperm cell that makes it motile (able to move)
  27. andr/o
    male

    example: androgen, testosterone is an androgen. The testes in males and the adrenal glands in both men and women produce androgens.
  28. balan/o
    glans penis (balanos=acorn in greek)

    Ex: balanitis, caused by overgrowth of organisms (bacteria and yeast)
  29. cry/o
    cold
