a) none of the above.

b) luteotropic hormone (lth)

c) luteinizing hormone (lh)

d) testosterone

question 13 (2.5 points)
which hormone stimulates the secretion of milk by the mammary gland?

a) follicle - stimulating hormone (fsh)

b) luteinizing hormone (lh)

Explanation:

For question 12, estrogen affects the secretion of follicle - stimulating hormone (FSH) and luteinizing hormone (LH), inhibiting lactation and ovulation. Testosterone is a male hormone and luteotropic hormone is mainly related to lactation promotion. For question 13, prolactin stimulates milk secretion by the mammary gland, while FSH and LH are mainly involved in the menstrual cycle and ovulation processes and not in milk - secretion stimulation. But among the given options for question 13, there is no correct answer as the correct one (prolactin) is not listed.

Answer:

Question 12: C. luteinizing hormone (LH)
Question 13: None of the above (since correct hormone prolactin is not listed)
