Does ADHD Have Anything To Do With Not Having Pubic Hair?

QUESTION:

Dear Dr. Heller,

I just found out that my 22 year old son has no pubic hair.  He is ADHD with learning disabilities and I believe has always had a chemical imbalance because he would always be super happy or super sad.  Would the ‘no pubic hair’ have anything to do with the imbalance and why does that happen?

ANSWER:

There is no relation with ADHD and lack of “secondary sexual characteristics” such as pubic hair.  Whether he has a “chemical imbalance” causing anxiety, depression or other psyche problems is unrelated. He needs to see an endocrinologist – someone who specializes in glandular function.
