4. What hormone stimulates testosterone production in males?

Follicle-stimulating hormone (FSH)

Luteinizing hormone (LH)

Gonadotropin-releasing hormone (GnRH)

Inhibin

5. Which describes the regulation of testosterone production inmales?

Negative feedback mechanism: When testosterone levels drop, thisinhibits hormone release by the anterior pituitary and thehypothalamus and testosterone levels rise

Positive feedback mechanism: When testosterone levels drop, thisinhibits hormone release by the anterior pituitary and thehypothalamus and testosterone levels rise

Negative feedback mechanism: When testosterone levels increase,this inhibits hormone release by the anterior pituitary and thehypothalamus and testosterone levels drop

Positive feedback mechanism: When testosterone levels increase,this stimulates hormone release by the anterior pituitary and thehypothalamus and testosterone levels drop

6. Which hormone is not involved in promoting spermatogenesis inmales?

Follicle-stimulating hormone (FSH)

Testosterone

Androgen-binding protein (ABP)

Inhibin

7. Which hormone is responsible for maturation of male sexorgans?

Growth hormone

Follicle-stimulating hormone

Luteinizing hormone

Testosterone

Androgen-binding protein

8. Which is not a function of testosterone?

Stimulates male pattern of development

Contributes to spermatogenesis

Contributes to male sexual behavior

Stimulates mammary gland development

9. Which statement about hormonal regulation of malereproductive function is wrong?

Gonadotropin-releasing hormone (GnRH) from the hypothalamusstimulates the release of follicle-stimulating hormone (FSH) fromthe anterior pituitary

The anterior pituitary releases androgen-binding protein(ABP)

Androgen-binding protein (ABP) maintains high levels oftestosterone

Luteinizing hormone (LH) stimulates the interstitial cells tosecrete testosterone

The anterior pituitary releases luteinizing hormone (LH)

10. Abnormally low levels of luteinizing hormone (LH) in thenormal male adult cause

Decreased testosterone secretion

Excessive growth of facial and body hair

Increased spermatogenesis

The anterior pituitary gland to shrink from lack of hypothalamicstimulation
