For this question, why can't the testosterone level be elevated? Is this because our body doesn't continuously make hormones randomly for no reason?


The answer is C.

The testosterone level could be elevated but that doesn't really answer the question. In these individuals, you would expect to see a slight buildup of testosterone because it doesn't get converted to DHT but that doesn't explain why male genitals would then develop in puberty. As it states in the passage, presence of testosterone is not sufficient for male genitalia development - it's DHT that stimulates it. So that means that in puberty, these males actually do start making DHT, which means that they must then be expressing the correct enzyme for doing so.
