One side effect of anabolic steroids to increase muscle bulk is that the testes shrink. Since the testes also produce testosterone, what is the likely mechanism for this shrinkage?
A) The anterior pituitary assumes overproduction and drops the level of hormones that cause the testes to develop.
B) Artificial testosterone causes a negative feedback to the anterior pituitary that in turn tries to stimulate ovary development.
C) Testosterone has a negative feedback effect directly on testes.
D) Artificial testosterone is toxic to testicular cells.
E) Excess testosterone actually backfires and reverses the effects of puberty.
Anabolic Steroids
Synthetic variations of the male sex hormone testosterone, often abused to enhance muscle growth and athletic performance.
Testicular Cells
Cells located within the testes responsible for the production of sperm and testosterone.
Negative Feedback
A mechanism that reverses a deviation from the set point in biological systems, helping to maintain homeostasis.

Final Answer :
A
Explanation :
The anterior pituitary senses the high levels of artificial testosterone and reduces the secretion of hormones like LH (Luteinizing Hormone) and FSH (Follicle Stimulating Hormone) that stimulate the testes to produce testosterone and sperm, leading to testicular shrinkage.
