Assault on the Male
Scientists believe that sperm counts in man have decreased by half over the last 50 years. Testicular cancer and malformations of male organs have become increasingly common. Biologists have also found evidence of alarming abnormalities in fish, alligators and other wildlife suggesting that the animals have become "feminised". From Florida swamps to Boston laboratories and male infertility clinics in Britain, Horizon tracks down the possible causes. Producer Deborah Cadbury Series editor Jana Bennett
