Donating blood?

I usually donate blood when the Red Cross blood mobile comes to work. Will this have any effect on T??
The reason I ask is I have read that blood supply to the ears can affect T. So if you are a pint low would it make a difference?

 

I used to donate blood back when my tinnitus was at a lower level. I never noticed any difference. Then again, I wasn't intently listening, either.

 

I might give it a try and see what happens.
