LH influences the corpus luteum to secrete progesterone, which peaks during the
a) luteal stage at day 12
b) follicular stage at day 21
c) follicular stage at day 12
d) luteal stage at day 21

Progesterone levels are high during the luteal stage to
a) maintain the uterus lining and calm uterus smooth muscle
b) cause a breakdown of the uterus lining and menstrual contractions begins
c) maintain the uterus lining and increase uterus smooth muscle contractions
d) cause a breakdown of the uterus lining and menopause begins

Human reproductive systems are regulated through negative and positive feedback loops. The correct operation of a feedback mechanism linked with a hormone is
a) LH secretion > positive feedback to ovaries; estrogen secretion > negative feedback to the pituitary
b) LH secretion > negative feedback to testes; testosterone > positive feedback to the pituitary
c) FSH secretion > positive feedback to ovaries; estrogen secretion : positive feedback to the pituitary
d) FSH secretion > negative feedback to testes; testosterone secretion > negative feedback to the pituitary
