An 18-year-old woman consulted a physician because of her failureto initiate menses. She had experienced normal breast developmentat age 13, but no pubic or axillary hair had ever appeared. Her heightwas 5 feet 6 inches, weight 119 pounds, blood pressure 110/70,and pulse 60 beats/minute. Her physical examination confirmedthe presence of well-developed breasts and the external genitaliaof a normal female. However, the vagina ended in a blind pouch,and there was no evidence of a cervix, ovaries, or a uterus. Withinthe inguinal area, the examining physician could palpate a small,spherical mass on each side. Is this patient’s genotype most likelyXX, XO, or XY? Explain why the genotype you selected is consistent with the manifestations
Understanding the causes of infertility can be valuablein developing new birth control methods. Cite a type ofcontraceptive based on each of the following causes ofinfertility:(a) failure to ovulate due to a hormonal imbalance;(b) a large fibroid tumor that disturbs the uterine lining;(c) endometrial tissue blocking uterine tubes;(d) low sperm count (too few sperm per ejaculate).
Normally deterioration of the endometrium begins when: blood levels of FSH increase blood levels of estrogen and progesterone decrease blood levels of estrogen and progesterone increase the corpus luteum secretes estrogen
For each hormone, select whether the hormone is increasing or decreasing at the beginning of parturition. In addition, select the correct effect that the change in hormone secretion causes. Hormone Levels Resulting Effect Increasing Decreasing Causes the endometrial layer to break away from the uterus Causes the endometrial layer to be maintained Increases uterine contractions Decreases uterine contractions Increases milk production in the mother's breasts Decrease milk production in the mother's breasts Hormone Hormone Levels Resulting Effect Estrogen Progesterone Oxytocin Prostaglandins Prolactin

Figure 43.15 Which of the following statements about hormone regulation of the female reproductive cycle is false? LH and FSH are produced in the pituitary, and estradiol and progesterone are produced in the ovaries. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. Both progesterone and estradiol are produced by the follicles. Secretion of GnRH by the hypothalamus is inhibited by low levels of estradiol but stimulated by high levels of estradiol.
Besides producing gametes (sperm and eggs), the primary male and female reproductive organs also produce sex hormones. The _____ and the pituitary gland control secretion of both.
Figure 43.8 Which of the following statements about the male reproductive system is false? The vas deferens carries sperm from the testes to the penis. Sperm mature in seminiferous tubules in the testes. Both the prostate and the bulbourethral glands produce components of the semen. The prostate gland is located in the testes.
If a 9-year-old male were castrated, what would happen to the levelsof GnRH, FSH, LH, and testosterone in his blood? What effect wouldthese hormonal changes have on his sexual characteristics and sexualbehavior as an adult?
Which of the following is/are true with regards hormones in the reproductive tract? * All the choices Progesterone is secreted by ovarian follicles & the corpus luteum. Estrogen secretion is stimulated exclusively by LH. Progesterone secretion is stimulated exclusively by FSH. Estrogen is secreted by ovarian follicles & the corpus luteum.
