Do I Have A Good Reason To Check Testosterone Levels?

Do I have a good reason to check testosterone levels?

Recently I am feeling a big drop in energy and productivity and whenever I lay down to rest for a few minutes it gets really hard for me to get back up and I get really exhausted and eventually fall asleep for a few hours. I am really tired and spent most of the time. I also have hair loss and it seems that at this rate in the near future I might become bald (seborrhea is the diagnosis). I also have the occasional mood swings. All of these according to what I read, are low test signs. However, my libido is okay and maybe even a little high considering I get horny quite a lot.. and I'm also able to grow facial hair pretty well.

Another reason I ask if I have a reason to do the checkup, is because I'm taking a drug called Risperdal. A quick Google search will show studies that have indicated that Risperdal can lower the levels of testosterone.

And on top of all that, I also have been diagnosed with varicocele and I heard that it affects the levels of testosterone too.

Given what I have written here, is there a good reason for me to get the test?
