28 year old male who recently had my testosterone levels checked. Results 410 ng/dl which my primary care tells me falls within the accepted range. However i'm currently being treated for depression as well as bi-polar dissorder and late on set ADD (possible symptoms of low T).The reason for my concerns at the moment is that over the past few years ive seen a noticable drop in my sexual performance and have finally had enough of it and need to know if my concerns seem reasonable, are there exceptions to the range? If so, where would i go from here to get the help I need?
