Human Reproduction Problem Set

Problem 1: Hormone released by hypothalamus

Tutorial to help answer the question

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:



With the onset of puberty, the hypothalamus increases the release of gonadotropin releasing hormone (GnRH). This hormone is needed for sexual maturity and normal reproduction.

GnRH stimulates the anterior pituitary gland to release several hormones. Among them are the gonadotropins"follicle stimulating hormone" (FSH) and "lutenizing hormone" (LH.)

These gonadotropins act by stimulating the production of sex hormones in the gonads (testes and ovary.)
