23 years old, low libido, need your input

[Structure]

Structure,

With AIS, were you able to keep all of your hair?

Also, if he has AIS, why is his LH only mid-range?

Yeah, I've still got all my hair. Sade is right that not everyone with AIS will have elevated LH (my LH is normal).

I still think it would be worthwhile to do a little more exploring in the OP's case. If it were me, I'd start by repeating the bloodwork to see if the low DHT was a lab error or a fluke. Then I'd test my fertility.
