Re: Low Testosterone
In a way you're lucky that the doctor picked up on it, but those are some pretty obvious symptoms. My doc ran the testosterone test when I complained of fatigue.
Keep after him, read up on the condition, be your own advocate. Dr. Shippen's book, The Testosterone Syndrome, is a good place to start, although it's now about 15 years old. You can probably get it through the library. If your doctor won't treat you, find a new doctor.
It's important to find out what's causing low T. Others on this board are knowledgeable about thyroid and other related issues. Do some reading in the older posts.
If you end up treating with testosterone, keep in mind that any testosterone added to your body (gel, patch, shots) will lower or shut down your own production and may destroy fertility. HCG can offset those changes. HRT (hormone replacement therapy) is usually for life, so you want to explore all other causes first.
