rs9332964 is a nonsynonymous change known as R227Q in the SRD5A2 gene. The
SRD5A2 gene encodes steroid 5-alpha-reductase, an enzyme which catalyzes the
conversion of testosterone in the body. Polymorphisms in SRD5A2 have been
implicated in several disorders of male sexual development such as
micropenis. The homozygous rs9332964(A;A) genotype has been observed in
several Japenese males with micropenis.

大多数研究的结果都是睾酮不足导致JJ过小,反过来推论睾酮过多的情形的确会有一定
风险,不过睾酮受体和下游通路应该没那么容易就饱和吧?

至于睾酮与攻击性的关系,wiki上有这么一段,其中最后一句话意味深长,呵呵。当然
