What are the possible complications of surgery?

No surgery is without risk however, the risk associated with this surgery is small.

An antibiotic injection is given during anaesthetic to reduce the risk of infection.  Complications such as bleeding at the site of scrotal incisions is usually minor although men are encouraged to rest for the first 24 hours following discharge and report any significant bleeding. 
 
Bleeding within the testis with damage to the testis occur rarely and if this happens further surgery may be required.  Anaesthesia itself is never without risk and the risks are greater for men who smoke or who are significantly over weight.
