Question

The gland(s) whose secretions help in sperm activation (2 points) a. The prostate b. The seminal vesicles c. The bulbourethral glands d. The seminiferous tubules e. The interstitial cells Question 2 Where does testosterone production occur? (2 points) a. Interstitial cells b. Myoid cells c. Seminal vesicles d. Seminiferous tubules e. Epididymis Question 5 Which describes the regulation of testosterone production in males? (3 points) a. Negative feedback mechanism: When testosterone levels drop, this inhibits hormone release by the anterior pituitary and the hypothalamus and testosterone levels rise b. Positive feedback mechanism: When testosterone levels drop, this inhibits hormone release by the anterior pituitary and the hypothalamus and testosterone levels rise c. Negative feedback mechanism: When testosterone levels increase, this inhibits hormone release by the anterior pituitary and the hypothalamus and testosterone levels drop d. Positive feedback mechanism: When testosterone levels increase, this stimulates hormone release by the anterior pituitary and the hypothalamus and testosterone levels drop Question 6 Spermatogenesis production is stimulated directly by (3 points) a. Testosterone b. Luteinizing Hormone (LH) c. Androgen-binding protein (ABP) d. Inhibin Question 7 Which hormone is primarily responsible for male secondary sex characteristics? (3 points) a. Growth hormone b. Follicle-stimulating hormone c. Luteinizing hormone d. Testosterone e. Androgen-binding protein Question 8 Which is not a male secondary sex characteristic? (2 points) a. Development of facial and body hair b. Lower pitched voice c. Increased bone density d. Development of testes as opposed to ovaries Question 9 Which statement about hormonal regulation of male reproductive function is wrong? (3 points) a. Gonadotropin-releasing hormone (GnRH) from the hypothalamus stimulates the release of follicle-stimulating hormone (FSH) from the anterior pituitary b. The anterior pituitary releases androgen-binding protein (ABP) c. Androgen-binding protein (ABP) maintains high levels of testosterone d. Luteinizing hormone (LH) stimulates the interstitial cells to secrete testosterone e. The anterior pituitary releases luteinizing hormone (LH) Question 10 A young boy (who has not gone through puberty) does not produce follicle-stimulating hormone because of an injury to his anterior pituitary. However, his production of luteinizing hormone is normal. After he has grown to maturity, what would be correct? (3 points) a. He would be sterile; without follicle-stimulating hormone, there would be no spermatogenesis b. He will not develop secondary sex characteristics; he would not secrete testosterone c. He will be impotent (unable to have an erection) since there is no testosterone secretion d. The function of his interstitial cells will be impaired and there would be no testosterone produced
