Use the following information to answer the next two questions.Birth control pills are oral contraceptives taken by women to prevent pregnancies. The most effective forms of birth control pills contain estrogen and a small amount of progestin (a synthetic hormone that mimics the effects of progesterone).
 
Question text
The role of estrogen in the birth control pill is to
Select one:
. reduce the progesterone levels in the blood to limit the endometrium buildup
suppress the shedding of endometrium, thus preventing menstruation
negatively feedback to the anterior pituitary to suppress the production of GnRH
 prevent a rise in the FSH and LH levels, thereby preventing follicle maturation
 
 
Teratomas in the pituitary glands are very rare tumours that occur in children and young adults. Usual symptoms of teratoma are diabetes insipidus, neurological issues, and a reduction in pituitary hormones.Which of the following correctly describes the symptoms of a 10-year-old girl with a teratoma tumour in the pituitary gland?
Select one:
 Decreased levels of ADH and inhibition of the development of secondary sexual characteristics
 Increased levels of ADH and stimulation of the development of secondary sexual characteristics
. Decreased levels of FSH and stimulation of the development of secondary sexual characteristics

Which of the following statements correctly describes the role of androgens in the male reproductive system?
Select one:
 GnRH is released by the anterior pituitary and stimulates the release of FSH and LH.
LH stimulates the Sertoli cells to produce inhibin and to start spermatogenesis.
Increased levels of inhibin released by the interstitial cells results in lower levels of FSH and testosterone.
Increased levels of testosterone feedbacks negatively to the anterior pituitary and hypothalamus.
 
 
Around day 21 of the 28-day cycle, administration of estrogen and progestin is stopped for 7 days. Low levels of progesterone result in
Select one:
menstruation, as the endometrium is built up and maintained by progesterone
. suppression of GnRH in the hypothalamus and FSH and LH in the anterior pituitary
 increased levels of estrogen released by the corpus luteum
 increased levels of FSH and LH, resulting in a mature follicle
