Morning Extra - The Investigation — Chlamydia

Are the BBC's biggest stars overpaid? A report commissioned by the BBC Trust is expected to clear the corporation of exceeding the going market rate for names like Jonathan Ross, Graham Norton and Terry Wogan. But are licence fee payers getting value for money? Plus, The Investigation looks at genital chlamydia. According to a respected Scottish consultant, around 30,000 Scottish males under 25 have no idea they're carrying the infection. Fewer still realise the damage it could do to their fertility, if left untreated. Journalist Pennie Taylor speaks to university researchers whose on-going research apparently proves beyond doubt that chlamydia damages sperm function. She attempts to get to the bottom of why so many young men are having unprotected sex and asks if poor sex education, alcohol abuse or poor adult role models are to blame? Graham Stewart takes your calls, texts and emails.
