Answer 24

1. produce androgens

2. stimulated by LH

Question 25

what do granulosa cells produce/ what are they stimulated by?

Question 28

what is defined as the period of CL development?

Answer 28

metestrus

Answer 37

granulosa cells

Question 38

what are some of the effects of estrogen on the body?
