  1. Sperm cells are stored primarily in the
    epididymides
  2. Undifferentiated spermatogenic cells are called
    spermatogonia
  3. The last fluid to be expelled from the urethra during ejaculation comes from the
    seminal vesicles
  4. Male reproductive functions are controlled mainly by hormones from the hypothalamus, and
    anterior pituitary gland and testes
  5. The hormone responsible for the development and maintenance of male secondary sexual characteristics is
    testosterone
  6. The female structure that corresponds to the male penis is the
    clitoris
  7. The hormone mainly responsible for the development and maintenance of female secondary sexual characteristics is
    estrogen
  8. About the time ovulation, the anterior pituitary gland releases a relatively large quantity of
    LH
  9. The tubular portion of the uterus that extends downward into the upper part of the vagina is the
    cervix
  10. The hormones mainly responsible for maintaining the uterine wall during the last 5-6 months of pregnancy are
    placental estrogen and progesterone
  11. In the menstrual cycle, estrogen functions to ___, whereas progesterone functions to ____.
    stimulate uterine wall development; stimulate the uterine lining to become more glandular
  12. The amount of testosterone in the blood is increased by
    LH causing the interstitial cells to release testosterone
  13. The most commonly used oral contraceptives contain
    synthetic estrogen and progesterone
  14. Which of the following is (are) the most reliable form of contraception?
    oral contraceptives
  15. Which of the following structures are unpaired?
    prostate gland
  16. In females, what structure is located immediately anterior to the vagina?
    urethra
  17. The interstitial cells of the testes produce
    androgens
  18. The cell commonly called the egg, or ovum, is more correctly called
    a secondary oocyte
  19. Fertilization normally occurs in the
    uterine tube
  20. The average length of the epididymis is
    6 meters
  21. If the testes fail to descend, a male is infertile because sperm cell formation is prevented by
    relatively high internal body temperature
  22. A Pap smear is used to detect the presence of abnormal cells in the
    cervix
  23. Following ovulation, a human egg cell can survive approximately
    24 hours
  24. An ectorpic pregnancy occurs when an embryo begins development
    outside the uterus
  25. One of the more common causes of female infertility is failure of ovulation due to hyposecretion of hormones from the
    anterior pituitary gland
  26. Which of the following terms is correctly defined?
    cryptorchidism-failure of testes to descend into scrotum
  27. The hormone commonly measured in a pregnancy test is
    hCG
  28. The epididymis, coiled on the outer surface of the testis, continues on to become the
    vas deferens
  29. Egg cells are transported in the female reproductive tract by the ___, whereas sperm are transported in the male reproductive tract by the____
    action of ciliated epithelium in the uterine tubes; movements of their tails
  30. The structure the sperm enters upon exiting the vas deferens is the
    ejaculatory tube
