Men can also have an artificial testicle, called a prosthesis , placed in the scrotum. The implant has the weight and feel of a normal testicle. This type of surgery does not change a man's ability to have an erection or an orgasm, but it can cause sterility because it interferes with ejaculation . Patients may wish to talk with the doctor about the possibility of removing the lymph nodes using a special nerve-sparing surgical technique that may protect the ability to ejaculate normally. Radiation therapy , also called radiotherapy, uses high-energy rays to kill cancer cells and shrink tumors.
Seminomas are highly sensitive to radiation.
Nonseminomas are less sensitive to radiation, so men with this type of cancer usually do not undergo radiation. Radiation therapy affects normal as well as cancerous cells. The side effects of radiation therapy depend mainly on the treatment dose. Common side effects include fatigue, skin changes at the site where the treatment is given, loss of appetite, nausea, and diarrhea. Radiation therapy interferes with sperm production, but most patients regain their fertility within a matter of months.
