Q

What does FSH do?

A

Helps us go from primordial follicle to primary follicle
Helps our follicles develop

17
Q

What does LH do?

A

Helps us make estrogen
Helps us make inhibin

18
Q

As inhibin and estrogen levels get too high what happens?

A

Turns everything off so follicles stop developing

19
Q

The graafian follicle does what?

A

Makes estrogen at such high levels that it causes the APG to release LH at high levels causing ovulation

20
Q

What happens when corpus luteum makes estrogen and progesterone at high levels?

A

Turns off FSH and LH production so we don’t make another follicle
