    3. produce approximately 60% of the semen volume
    4. both A. and B.
    5. both A. and C.

  2. "Descent of the testes" refers to

    2. the sperm must metabolize external carbohydrates and other external fuel sources
    3. the oocyte ("egg") is initially covered by layers that block sperm penetration
    4. if testosterone levels become too high, the pituitary gland may get "shut off"

    2. tropic hormones produced by the pituitary gland
    3. produced only in the bodies of pregnant women
    4. produced only in the bodies of women (whether pregnant or not pregnant)

  14. Which statement is not true of testosterone?
    1. chemically, is a steroid
    2. causes general development of the male reproductive system
    3. causes development of secondary male characteristics (facial hair, etc.)
    4. stimulates pituitary gland to produce FSH and LH

  15. Follicle stimulating hormone (FSH)
    1. is produced only by a membrane that surrounds an embryo
    2. promotes development of ovarian follicles
    3. inhibits production of estrogens
    4. all of the above

  16. During week two of an ovarian cycle,
    1. the corpus luteum is producing progesterone
    2. the ovarian follicles are producing estrogens
    3. low levels of ovarian hormones cause menstruation
    4. the pituitary gland is secreting human chorionic gonadotropin

  17. In a 28 day ovarian cycle, ovulation occurs on day(s) _?_ as a result of _?_.
    1. days 1 through 5 / low levels of ovarian hormones
    2. day 14 / high levels of LH
    3. days 20 to 21 / high levels of progesterone
    4. days 22 through 28 / low levels of progesterone

  18. The corpus luteum
    1. is released from the ovary at the time of ovulation

    3. forms from one of the membranes that surrounds an embryo, and develops into the placenta
    4. is shed from the uterus during menstruation

  19. Progesterone
    1. supports the endometrium of the uterus (prevents menstruation)
    2. stimulates the release of gonadotropins from the pituitary gland
    3. is present in the body fluids of pregnant women only (basis of pregnancy test)
    4. all of the above

  20. In a woman who is not pregnant, the progesterone level during week four
    1. increases until menstruation occurs
    2. increases, which leads to menstruation
    3. decreases, which leads to menstruation
    4. stays the same as it was during week three

  21. Human chorionic gonadotropin (hCG) is produced by
    1. the pituitary gland
    2. an ovary, prior to ovulation
    3. an ovary, after ovulation has occurred
    4. a membrane that surrounds an embryo

  22. In a woman who is pregnant,
    1. human chorionic gonadotropin (hCG) sustains the corpus luteum so it can secrete progesterone
    2. progesterone maintains the endometrium so that menstruation does not occur
    3. progesterone inhibits the release of FSH from the pituitary gland so that a new ovarian cycle does not begin
    4. all of the above
