4.) Which of the following are TRUE? Select one or MORE:

a. Lower progesterone in women can result in a shorter luteal phase.

f. oxytocin released during nursing acts on sexual arousal centers in the brain

6.) What would happen to the GnRH and LH levels of a woman who received daily treatment with a drug that prevented estradiol from being detected by estrogen receptors during the early follicular phase of her menstrual cycle?

c. GnRH release would increase and LH release would decrease

d. Both GnRH and LH release would decrease

Answer 1

1. Answer : a) The combination pill contains progesterone and estrogen which act as negative feedback on GnRH, FSH and LH, so no ovulation occurs.

d) The progesterone in the pill acts on the endometrial lining so implantation fails to properly take place.

3. Answer : a. Prolactin triggers the production of milk.

b. Oxytocin triggers the expulsion of milk and contractions of the myometrium.

d. Sucking on the breast triggers the hypothalamus to cause the anterior pituitary to produce prolactin and the posterior pituitary to produce oxytocin.

The action of prolactin triggers the production of milk. Oxytocin triggers the expulsion of milk and contractions of the myometrium. Sucking breast triggers to produce prolactin and oxytocin. These are the statements which are true.

4. Answer : a. Lower progesterone in women can result in a shorter luteal phase.

b. A very light menstruation in a woman can be the result of low progesterone levels.

5. Answer : c. oxytocin released during nursing causes uterine contractions similar to those during orgasm.

d. prolactin causes the production of milk, while oxytocin causes the milk to be expelled. Oxytocin acts on the myoepithelial cells causing them to contract.

e. nursing is the stimulus for milk production and expulsion.

f. oxytocin released during nursing acts on sexual arousal centers in the brain.

These are the reasons that she experiences pleasurable sexual sensations when nursing her infant.

6. Answer : a. Both GnRH and LH release would increase.
