I am 22 years old before 8 month i operation the ignual hernia it is 3-4 years then i operate this it is effect on my penis size?

No: Operations for inguinal hernia repair have no effect on penis size unless there is a tragic complication. There is no reliable way to change your penis size for better or worse. The most common cause of perceived change in penis size is weight gain or loss. For each 10lb fat gain your penis can appear to be 1/2 inch shorter. For each 10lb loss you can gain an apparent 1/2 inch.
