Most men exposed to DES before birth have no known increased risk of health problems. However, some DES sons do face an increased risk for problems with their genital organs. These range from harmless irregularities to problems which may require medical treatment. Many people, including some doctors, do not know that men can be affected by DES exposure before birth. The epididymis is a structure on the back of each testicle where sperm are stored.
Epididymal cysts are non-cancerous growths that feel like small lumps.
They may disappear and recur over time. They do not need to be treated unless they are painful. However, report all lumps to your doctor and perform testicular self-exams on a monthly basis. Both of these abnormalities are visible at birth. A varicocele is an irregularly swollen or varicose vein on the testicle.
