Chapter 28, Problem 2CT
Summary Introduction
To determine:
The effects of castration of 9-year-old male on the levels of GnRH, FSH, LH, and testosterone and also the effect on sexual characteristics and sexual behavior as an adult.
Introduction:
In males, the process of removal of the testicle is referred to as castration. Before puberty, the levels of GnRH (gonadotropin-releasing hormone) are low in the body. The low levels of GnRH are also responsible for the low levels of FSH (follicle-stimulating hormone) and LH (luteinizing hormone).
