Human Reproduction Problem Set

Problem 1: Hormone released by hypothalamus


The hormone released by the area of the brain known as the hypothalamus beginning at the onset of sexual maturity in both males and females is:

A. follicle-stimulating hormone (FSH)
B. lutenizing hormone (LH)
C. progesterone
D. gonadotropin releasing hormone
GnRH is needed for sexual maturity and normal reproduction. GnRH acts by stimulating the release of luteneizing hormone and follicle-stimulating hormone from the anterior pituitary. These two gonadotropins act by stimulating the production of sex hormones in the gonads (testes and ovary).
E. testosterone
