Lee Little has been using steroids for 25 years and has now been told his sperm count is zero.

Speaking to BBC Radio 5 live Breakfast he says "It just isn't worth it for your health risks. People are taking insulin now to gain weight but you can go into a diabetic coma".

The director of the one of the country's biggest drug treatment centres says that steroid abuse is a 'ticking time-bomb'.

David Smallwood from the One40 clinic in London says more people than ever are taking steroids - and storing up enormous health problems for themselves as they do so.
