Are there health affects for DES Sons?
DES exposure can also affect men. Some DES Sons (whose mothers took DES while pregnant with them) run a higher risk for one or more genital problems, including undescended or underdeveloped testicles, cysts on the back of the testes (on the epididymis) and lowered sperm count. DES Action is calling for more studies to determine whether DES Sons face an increased risk for cancer or other health problems.
