Subsequent to varicocelectomy, testicle has grown huge?

Possible hydrocele: This occurs in about 15% of men after a varicocelectomy/spermatic vein ligation ; likely due to lymphatics being tied off at time of surgery. U might want to have a hydrocelectomy if your left scrotum is now unpleasantly large.

May be hydrocele ...: How long ago did you undergo varicocelectomy, and how was it done? These may potentially affect the current size of scrotum. This procedure would not make testicle bigger; instead, it may make testicle smaller if testicular artery is inadvertently severed. The common reason for "huge" testicle is hydrocele, which is fluid filling up the space between scrotal wall & testis. So, ask Doc.
