Hv left sided ingiunal hernia hv noticed significent penis reduction as hernia enlarged?

No penile changes.: Inguinal hernias will not change the size of the penis. If the hernia bulge is large, is can obscure the base of the penis making it appear shorter than it is, especially if the hernia is in the scrotum. If the hernia is bothersome or enlarging, consult with a general surgeon. Depending on the risk of complications such as incarceration or strangulation, the doctor may recommend repair.

It's Reversible: I agree with dr. Kimm's excellent answer. If your hernia is large enough to extend into your scrotal sac and obscure your penis, it's time to get that hernia repaired. Having repaired a number of hernias like what you have described, rest assured that everything will eventually look normal again after your surgery.
