If you have a defect that blocks the release of gonadotropin-releasing hormone (GnRH) from the hypothalamus, which of the following statements would be true? A. Only females would be affected; folliculogenesis would be disrupted by the loss of FSH. B. Sex doesn't matter; both folliculogenesis and spermatogenesis would be disrupted. C. Only males would be affected; spermatogenesis would be disrupted by the loss of FSH. D. There would be no defects.

Step 1
Step 1: A defect that blocks the release of gonadotropin-releasing hormone (GnRH) from the hypothalamus will lead to a lack of stimulation of the anterior pituitary gland to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Show more…

Which of the following statements about hormone regulation of the female reproductive cycle is true? a. LH and FSH are produced in the ovaries, and estradiol and progesterone are produced in the pituitary. b. Estradiol and progesterone secreted from the corpus luteum cause the myometrium to thicken. c. Progesterone is produced by the corpus luteum. d. Secretion of GnRH by the hypothalamus is inhibited by high levels of estradiol, but stimulated by low levels of estradiol.
Which statement MOST accurately describes the role of sex hormones in spermatogenesis? A. Spermatogenesis is regulated by luteinizing hormone secreted by the testis. B. Spermatogenesis is regulated by luteinizing hormone secreted by the hypothalamus. C. Spermatogenesis is regulated by gonadotropin-releasing hormone secreted by the testis. D. Spermatogenesis is regulated by gonadotropin-releasing hormone secreted by the hypothalamus.

Before puberty $a$. the pituitary secretes luteinizing hormone and folliclestimulating hormone, but the gonads are unresponsive. $b$. the hypothalamus does not secrete much gonadotropinreleasing hormone. c. males can stimulate massive muscle development through a vigorous training program. $d .$ testosterone plays no role in development of the male sex organs. e. genetic females will develop male genitals unless estrogen is present.
