...Thanks for the advise and support man. You said you went through the same thing. Did you ever get that resolved?
You're welcome. As for getting my own problems resolved, I'm sorry to say that the answer is no, I haven't, but I should also say that I haven't really been trying to do anything about it. I haven't been taking my own advice.
I only got as far as seeing my doctor. I just went to my regular doctor, not a specialist. As I mentioned in my reply to bobs3304, I had my testosterone levels checked. I got the results in the mail. They were normal. I have not yet gone back to my doctor to see if he has any other ideas with regards to causes or treatments, but I think I will call this week and set up an appointment. Replying to you and bobs has kinda given me the kick in the pants I needed to deal with my own shit.
With regards to testosterone levels, there's no universal agreement on what "normal" is. My doctor says normal is 200-1200, which is quite a significant range. But I did a little bit of research and some labs use a different scale, like 300-1500. Some say that age should be considered in interpreting the results. For example, someone in his 20s should be at the high end of normal, someone my age should be a bit lower, and so on, as the age goes up.
Low testosterone can have symptoms other than lack of libido, including loss of muscle mass, loss of bone density (sometimes leading to osteoporosis), hair loss (including body hair), shrinking of the penis, memory loss, inability to concentrate, depression, mood swings, and decreased performance in all areas of life.
My testosterone level was 355, which is within the normal range, but definitely at the low end of normal. I also had my "free testosterone" levels measured. The normal range is 10-55. Mine was 17, so again, that's at the low end of normal. It's probably unusually low for someone my age. Personally, I think this is the reason for my lack of libido. I have enough testosterone to maintain my body, there isn't enough leftover to "fuel" my libido, so to speak.
If I'm right, and I need to talk to my doctor again to find out, I'll have to find out what my options are. I'm afraid he's going to say that there's nothing he can do, which is one of the reasons I haven't gone back yet.
