Summary Introduction
To draw: A diagram that explains the use of exogenous anabolic steroids which can shrink a man’s testes and make him temporarily infertile.
Introduction: The sex hormone secreted by an individual affects the secondary sexual characteristics of an individual as well as contribute to the development of sex hormones. Anabolic steroids are human are synthetic molecules that are analogous to the testosterone hormone.

Progesterone:
1) Is produced in adult testes and is responsible for genital development, beard growth, muscle development, and sexual drive
2) Is produced by the placenta during pregnancy, with highest levels seen at conception and then steadily decreasing to non-detectable levels at term
3) Is lowest is serum during the luteal phase of the menstrual cycle and highest during the follicular phase
4) Parallels activity of the corpus luteum by rapidly increasing following ovulation and then abruptly falling to initial low concentrations prior to the onset of menstruation
