I have an 18 yr old that has Klinefelters Syndrome (XXY male), and is taking testosterone injections. It is going well, but I wondered if there was anyone else who has experience with this condition? He was not properly diagnosed until he was 15! At 8 yrs old they tried o tell me he was bipolar and had him on lithium and antipsychotics! Thank heavens I didn’t buy that and kept searching for answers. Anyone?
