Question

• A. Estrogen
• B. Luteinizing
• C. Luteotrophin
• D. Gonadotrophin
• E. Both B and C

Answer 1

The correct option is E Both B and C

Prolactin is a peptide gonadotrophic hormone secreted by the pituitary gland; it stimulates growth of the mammary glands. Progesterone, secreted from the corpus luteum, prolongs the secretion of prolactin. Luteinizing hormone is a hormone produced by gonadotroph cells in the anterior pituitary gland. In females, an acute rise of LH triggers ovulation and development of the corpus luteum.
