high testosterone without high androgenisation is kind of a hallmark of AIS. i mean....it kind of defines the condition, yeah? the other potential thing you might be looking at is 5a reductase deficiency, although that generally (but not always) presents with ambiguous genitalia/hypospadias. 5a reductase will show normal/high testosterone, undervirilisation, and extremely low/absent dihydrotestosterone levels.
