Hello. I donated in late 2008 and immediately had pain in left testicle. Swelling and prostate symptoms followed. Today, almost 10 years post op, left testicle is swollen up to about 3-4 times normal size. I am hoping to get in to a urologist here in Houston asap, but long story short, 1) this should be a disclosed risk (left testicle pain or symptoms seem to be very common after donation), and 2) i chose to ignore it but is has gotten worse, i assume fluid draining surgery is in my future.
