Chapter 36, Problem 4TYU
Summary Introduction
Introduction:
LH (luteinizing hormone) and FSH (follicle stimulating hormone) are gonadotropins released in the body by the anterior pituitary. They stimulate the gonads (testes in males and ovaries in females) and thus play an important role in reproduction.

This causes all of the following EXCEPT
Select one:
A. The maintenance of the corpus luteum to continue producing low levels of progesterone and estrogen.
