  4. After being produced, sperm next enter the _?_ for storage.
    1. epididymis
    2. prostate gland
    3. seminal vesicles
    4. seminiferous tubules

  5. Which usually has a lower pH?
    1. semen
    2. vagina
    3. none of the above (they are maintained at the same pH)

  6. The vas deferens originates within the _?_ and passes to the _?_.
    1. testis / epididymis
    2. testis / prostate gland
    3. scrotum / region posterior to (behind) the kidney
    4. scrotum / region posterior to (behind) the urinary bladder

  7. The greatest percentage of the volume of semen is produced by the
    1. seminiferous tubules and interstitial cells
    2. epididymis and vas deferens
    3. seminal vesicles and prostate gland
    4. corpora cavernosa and corpus spongiosum (erectile bodies of penis)

  8. Primordial follicles (the earliest stage of follicle development) arise in the ovaries
    1. in large numbers prior to birth
    2. in large numbers after birth but prior to puberty
    3. in large numbers following puberty
    4. one at a time during each ovarian cycle

  9. When a mature follicle ruptures,
    1. large amounts of ovarian hormones are suddenly released
    2. an oocyte, along with some follicular cells, is released
    3. the oocyte and hormones are immediately taken into the uterus
    4. all of the above

  10. Following ovulation, the part of the follicle that remains in the ovary becomes the
    1. blastocyst
    2. endometrium
    3. corpus luteum
    4. secondary follicle

  11. The normal site of fertilization of an oocyte is within the
    1. blastocyst
    2. corpus luteum
    3. uterine tube
    4. uterine cavity

  12. The endometrium
    1. is the layer of the uterine wall closest to the uterine cavity
    2. is the normal site of implantation of an embryo
    3. is shed as menses if fertilization does not occur
    4. includes a deeper, permanent layer for regeneration of tissue following menstruation
    5. all of the above

  13. The "tropic hormones" that control the ovaries and testes are
    1. called "gonadotropins"
    2. produced by the pituitary gland
    3. the only known hormones that are not subject to the principle of "negative feedback"
    4. both A. and B.
    5. all of the above

  14. Testosterone
    1. is the same as "follicle stimulating hormone" (FSH), the name by which it goes in females
    2. stimulates development of male reproductive organs
    3. causes male secondary sex characteristics
    4. both B. and C.
    5. all of the above

  15. Which one of the following is an ovarian hormone that has major responsible for puberty in females?
    1. estrogen
    2. progesterone
    3. luteinizing hormone (LH)
    4. follicle stimulating hormone (FSH)
    5. human chorionic gonadotropin (hCG)

  16. Which hormone can be said to be the one that "starts" each ovarian cycle?
    1. estrogen
    2. progesterone
    3. luteinizing hormone (LH)
    4. follicle stimulating hormone (FSH)
    5. human chorionic gonadotropin (hCG)

  17. At the time that ovulation occurs, the endometrium is
    1. "gone" (not replaced since the last menstrual flow)
    2. at an intermediate thickness, due mainly to estrogens
    3. at its thickest, due to progesterone
    4. a convoluted yellow mass called the "corpus luteum," awaiting activation by hormones

  18. A dramatic "surge" or "spike" in the production of luteinizing hormone (LH)
    1. occurs late in week two of each ovarian cycle
    2. causes ovulation
    3. serves mainly to "shut down" the pituitary gland to prevent multiple pregnancies
    4. both A. and B.
    5. both B. and C.

  19. During week three of the ovarian/uterine cycle,
    1. the embryo, if present, is being moved toward the uterus
    2. progesterone is maintaining the endometrium (preventing menstruation)
    3. progesterone is stimulating the pituitary gland to produce more FSH and LH
    4. both A. and B.
    5. all of the above

  20. Relatively high levels of progesterone are likely to
    1. stimulate the development of additional ovarian follicles
    2. inhibit the development of additional ovarian follicles
    3. have no effect on the development of additional ovarian follicles

  21. Normally, the elapsed time from ovulation to the start of menstruation is
    1. one week
    2. two weeks
    3. three weeks
    4. four weeks

  22. In a woman who is not pregnant, menstruation is caused by the
    1. appearance of the corpus luteum
    2. increase in the level of LH ("LH surge")
    3. increase in the level of human chorionic gonadotropin (hCG)
    4. decrease in the level of progesterone

  23. Human chorionic gonadotropin (hCG)
    1. is produced by an embryo
    2. serves as a signal to begin producing FSH and LH
    3. serves as a signal to continue producing progesterone
    4. both A. and B.
    5. both A. and C.
