That was the entire point of my post. If the only problem is low T, there should be absolutely zero need for PDE5 inhibitors to function. Other issues, like vascular, performance anxiety, etc and now we are talking about a multiple diagnosis issue which goes beyond just TRT.
And too many guys...
Agreed, which could have many causes. That's why I tried to make it clear in my post that if the only issue a guy was having was low production of testosterone, they shouldn't need ED drugs unless there is another underlying issue, whether it be vascular, performance anxiety, etc. But so many...

It drives me crazy when guys say "I...

Understanding Your Hormones
Estradiol (E2)
A form of estrogen produced from testosterone. Important for bone health, mood, and libido.
Too high can cause side effects; too low can affect well-being.
DHT
Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth,
prostate health, and masculinization effects.
Free Testosterone
The biologically active form of testosterone not bound to proteins.
Directly available for cellular uptake and biological effects.
