re: How to interpret testosterone results? And what to do about it?

I assume by the number you posted you are speaking of free test like pepe said. First, that is still low, second without getting total test number you have no way to know what the issue is. You are only seeing a small part of the bigger picture.

Yes all the things listed will impact results, but I would still be concerned.

Don't go see a low t center, most are quakes but on the opposite end of the spectrum from a GP. It's a option but only if there are no better options. I would first find a good urologist and ask to be referred to him and have your blood work sent over and do another test in 12 weeks making sure you eat well and exercise consistently u til then. From there post your blood work and a couple here can help along with a good urologist.

Don't take no for an answer or the generic, it's in the normal range, as an answer either. That range is for 18-80 year man and unless they use the charts adjusted for age, then it's bullshite.
