Are there side effects of germ cell tumor surgery?

It depends: Side effects of orchiectomy (testicle removal) alone are fairly limited. Major abdominal surgery however is sometimes necessary and can result in ejaculatory dysfunction, bowel obstruction, hernia or leakage of lymphatic fluid. This type of operation is best done at a major referral center where complication rates are lowest. Lung and brain surgery are sometimes necessary though less commonly.
