Hi
I too was diagnosed with low testosterone levels about 6 months ago. I have been a type 1 for about 12 years and hypothyroidism was also diagnosed at the same time.
My low levels of testosterone are caused by a pituitary adenoma diagnosed from an initial blood test where this showed an elevated level of the hormone prolactin. This was suppressing the testosterone. An MRI scan revealed the tumor.
I currently take Cabergoline to help lower the prolactin levels which hopefully should start to raise my testosterone naturally. Which it has done, albeit a small increase it's showing signs on increasing. It's a long drawn out process and I am hoping not to have to take testosterone replacement therapy for it.
Whether the tumor was the cause of my diabetes and hypothyroidism ...who knows...my endocrinologist does not really know either, but at least you have been able to get somebody to recoqnise your low testosterone levels as it can be extremely difficult to get the medical profession to take you seriously....instead of "it's just your age"....I was 43 when diagnosed and my testosterone was 5.8.
Just getting my initial energy and motivation for everything in life back, has been a great boost. All caused by the low testosterone.
Regards
Rusty
