- Figure 18.17 Which of the following statements about hormone regulation of the female reproductive cycle is false? a. LH and FSH are produced in the pituitary, and estrogen and progesterone are produced in the ovaries. b. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. c. Both progesterone and estrogen are produced by the follicles. d. Secretion of GnRH by the hypothalamus is inhibited by low levels of estrogen but stimulated by high levels of estrogen.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.How Is Sex Determined? The absence of a Y chromosome in an early embryo causes the: a. embryonic testis to become an ovary b. Wolffian duct system to develop c. Mllerian duct system to degenerate d. indifferent gonad to become an ovary e. indifferent gonad to become a testis
- Which hormone causes FSH and LH to be released? a. testosterone b. estrogen c. GnRH d. progesteroneWhat is the primary role of FSH in males? Develop and maintain secondary sex characteristics Initiate sperm production in the testes Stimulate the interstitial cells to produce testosterone Stimulate the nurse cells to produce inhibin Influence sexual behaviors and sex driveWhich of the following statements is NOT true concerning the hormonal control over the male reproductive system? These hormones are involved in a negative feedback relationship The hypothalamus secretes a hormone called gonadotropin-releasing hormone Luteinizing hormone controls the production of sperm in the seminiferous tubules Follicle-stimulating hormone and luteinizing hormone are present in both males and females The interstitial cells produce testosterone
- What are the main effects of gonadotropic hormones? Select all that apply. Stimulation of the formation of the ova Stimulation of the secretion of hormones from sex Stimulation of the development of secondary female sexual characteristics Stimulation sustains pregnancy Stimulation of the hormone progesteroneHypogonadism is a condition where the body does not produce enough testosterone. The symptoms of hypogonadism include infertility and a decrease in secondary sex characteristics. There are two types of hypogonadism. Primary hypogonadism is caused by problems stemming from the testicles, and secondary hypogonadism is caused by problems stemming from the hypothalamus or the pituitary gland. Individuals with hypogonadism are often treated with testosterone replacement therapy. What would be the result of testosterone injections in individuals with hypogonadism? Select one: a. GnRH LH Testosterone Decrease Decrease Increase b. GnRH LH Testosterone Decrease Decrease Decrease c. GnRH LH Testosterone Increase Increase Increase d. GnRH LH Testosterone Increase Increase DecreaseMatch four of the hormones of the negative feedback numbered above with their function given below. Function: Hormone: Stimulates the development of an ovum Answer Stimulates the corpus luteum to release progesterone Answer Suppresses GnRH, FSH, and LH production in the follicular phase Answer Suppresses GnRH, FSH, and LH production in the luteal phase Answer
- People with androgen insensitivity syndrome show developmental abnormalities. Which of the following primary or secondary sexual characteristics is most likely to be seen in these individuals? The presence of: a prostate a penis breast development at puberty descended testes pubic and axillary hairincreased levels of estrogen and progesterone will result in ( negative, positive, increase, decrease) feedback to the hypothalamus and anterior pituitary to ( negative, positive, increase, decrease), ( LH, FSH, GnRh, LH AND FSH) production. This normally occurs during the ( FOLLICULAR STAGE, LUTEAL STAGE ) Decreased levels of estrogen and progesterone will result in ( negative, positive, increase, decrease) feedback to the hypothalamus and anterior pituitary to ( negative, positive, increase, decrease), (LH, FSH, GnRh, LH AND FSH) production. This normally occurs during the ( FOLLICULAR STAGE, LUTEAL STAGE ). Extremely high levels of estrogen near the end of the follicular phase will result in ( negative, positive, increase, decrease) feedback to the hypothalamus and anterior pituitary to release a large amount of ( LH, FSH, GnRh, LH AND FSH) to trigger ovulation. Some hormones are used in oral contraceptive pills to suppress the release of ( LH, FSH, GnRh, LH AND FSH) Without…Which of the following mechanisms best explains the contraceptive effect of birth control pills that contain both synthetic estrogen and progestin? Inhibition of ovulation Impairment of implantation hyperplastic changes of the endometrium Production of uterine secretions that are toxic to developing embryos Impairment of sperm transport due to uterotubal obstruction Direct inhibition of oocyte maturation
