i have a hernia that will be repaired in about 3 weeks and personally have not had an issue with this. however my doctor has told me and i have read that sometimes the vas deferens can become strangulated by the intestine intruding into the scrotum. the "vas" is the tube that carries the sperm. if you are having trouble and you think it may be related to your hernia see your doctor immediately as a strangulation of any kind can be very serious. read some of the categories relating to strangulation.
does a hernia affect being able to ejaculate before having the surgery?
