[|Human|] My tescticles seem to be reducing in size but no lump or pain whatsoever, i am 50 years of age. My sex drive has reduced considerably and i can hardly sustain normal erection enough for penetration. I exercise normaly and regularly and eat well. I also use viagra from time to time.
[|AI|]  Degree understand your concerns went through your details. The size of the testicles do not reduce. But the surrounding sack shrinks. That is natural. That happens due to many reasons including stress and deny Chat Doctor.  Erectile dysfunction is possibly physiological rather than psychological in your case. You are also having Viagra occasionally. Viagra is known addictive on erection matter. I request you to consult your urologist for further advise.
