I have not seen anything that shows that link.
My personal opinion is that libido is extremly complex and is influenced by many factors including blood chemistry, physical and mental state, physical conditioning and diet.
Something that can destroy one person's libido can cause a no-effect to somebody else, or even a libido increase - its bizarre and complex.
And if it weighs heavilly on your mind, you can psyche yourself out in sexual situations if you are not carefull.
