Assault on the male update.

The earlier programme looked at research in 1993 following the discovery of abnormalities in human sperm which led scientists in Copenhagen to research the potential causes of these changes, as well as other changes in male reproduction like the trebling of incidence of testicular cancer over the last 30 years in the UK and US. Changes in modern living increasing levels of oestrogen were thought to be threatening males of different species, from alligators to human. This programme recaps the findings of the first programme and brings them up to date.
