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).

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

Increased levels of FSH and inhibition 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

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

Hormone replacement therapy (HRT) is common treatment for postmenopausal women. It is often used to relieve the symptoms of menopause; and one of the benefits of HRT is the reduction in osteoporosis-related fracture cases.Which of the following structures performs a similar function in the female reproductive system as hormone replacement therapy would?

Select one:

Anterior pituitary gland

. Hypothalamus

Maturing follicle

Ovum

One of the roles of follicle stimulating hormone (FSH) in the female reproductive system is

Select one:

. to promote menstruation during the follicular stage

to promote menstruation during the luteal stage

to trigger the thickening of the endometrium in the follicular stage

to trigger the thickening of the endometrium in the luteal stage

The endometrium rebuilds primarily during what phase of the menstrual cycle?

Select one:

Luteal stage

It is continuously rebuilding

Follicular stage

Uterine cycle

Although the most effective forms of oral contraceptive for women contain estrogen and progestin, some birth control pills contain a small dose of progestin only. This is because there are many risks and side effects associated with estrogen.Which of the following statements is NOT a reason for using a progestin-only oral contraceptive?

Select one:

Progestin-only oral contraceptives prevent the production of FSH and LH in the anterior pituitary.

Prgesterone suppresses the production of GnRH in the hypothalamus.

Progesterone suppresses the maturation of follicles, thereby preventing ovulation of a mature ovum.

Progesterone maintains the corpus luteum as corpus luteum releases a large amount of progesterone and some estrogen.

Each of the four female reproductive hormones (FSH, LH, estrogen & progesterone) have specific roles or functions to complete to ensure a successful pregnancy. While these hormones may be released at different time during an average 28 day cycle there are key times in the cycle where their release is critical in ensuring a successful pregnancy.

Which of the following lists the order of hormonal release from days 0-28 required to support the fertilization and implantation of the ovum?

Select one:

LH, FSH, estrogen, progesterone

FSH, estrogen, progesterone, LH

FSH, LH, estrogen, progesterone

FSH, estrogen, LH, progesterone

Which of the following statements does NOT correctly describe the role of inhibin in the male reproductive system?

Select one:

Sertoli cells produce sperm and secrete inhibin.

Increased levels of inhibin suppress the production of follicle stimulating hormone.

Inhibin decreases the production of sperm.

Low levels of inhibin result in decreased production of sperm.
