Not at all. Everything, with the exception of ejaculation, is the same - operationally and size wise.
But I never suffered ED either before or after and the atrophy of disuse can cause shrinkage. I was told that if something did happen then I should use a pump until I recovered or got an implant to prevent the urethra from shrinking, thus causing the penis to also shrink.
I've never heard of testicular shrinkage as the result of RARP, but perhaps testosterone treatments caused that.

Men on ADT will have testicular shrinkage because the medication (Lupron etc) tells the pituitary gland to stop producing the hormone (LH) which stimulates the testicles to produce testosterone. In essence, the "factory" shuts down and the testicles shrink.
Likewise, testosterone replacement therapy will result in testicular atrophy because the feedback to the pituitary is there is plenty of T in the bloodstream (from the exogenous T) so, again, the pituitary signals the testicles to stop production and they shrink.
An RP by itself does not result in shrinkage of the penis or testicles. But, if men lose the ability to have erections then some penile atrophy can occur. You are right that a pump and daily generic Cialis can help prevent that.
