Question

why might anabolic steroid use lead to testicular shrinkage in men? *
1 point
steroids cause physical damage to testicles
steroids increase sperm production excessively
steroids suppress natural testosterone production
steroids cause infections that shrink testicles

Explanation:

Anabolic steroids are synthetic forms of testosterone. When men take anabolic steroids, the body detects high testosterone levels and reduces or stops natural testosterone production by the testes (via negative feedback). Without the stimulation from natural testosterone production signals, the testes can atrophy (shrink) as they are not being used to produce testosterone at normal levels. The other options are incorrect: steroids don’t directly cause physical damage (option A) or infections (option D) leading to shrinkage, and they don’t increase sperm production to cause shrinkage (option B).

Answer:

C. Steroids suppress natural testosterone production
