19
Q

During the follicular stage of menstrual cycle, the LH level ( declines/rises).

20
Q

Androgens (androstenedione) are transported to the granulosa cells and then are converted to which hormone by granulosa aromatase?

21
Q

Inhibitin B (stimulates/inhibit)s androgen synthesis.

A

Stimulates

22
Q

Inhibitin B (stimulates/inhibits) FSH secretion.

23
Q

As the follicular phase progresses, FSH levels decline why?

A

Due to negative feedback by estrogen to hypothalamus and inhibitin B inhibition of FSH secretioin

24
Q

FSH stimulates (estrogen/progesterone) secretion.

25
Q

LH stimulates (estrogen/progesterone) secretion.

A

Progesterone

26
Q

What is the correct sequence of events in luteal phase

Estrogen and progesterone levels fall
LH and FSH fall,
LH surge,
corpus luteum dies,
corpus luteum secrete large amount of progesterone,
A

1) LH surge,
2) Corpus Luteum secrete large amount of progesterone,
3) LH and FSH fall,
4) Corpus luteum dies,
5) Estrogen and progesterone levels fall

a. Follicular
b. Menstrual
c. Luteal

36
