With Jenni Murray. Despite its complicated heroine and challenging storyline, for centuries the myth of Medea has captivated audiences the world over. With another version set for the stage, the programme explores why this myth about female fury, passion and pain has become so enduring. Many fertility clinics struggle to recruit donors, have long waiting lists for those needing treatment and in some areas have ceased to provide treatment services altogether. Some say the shortage can be attributed to the removal in 2005 of entitlement to donor anonymity. Jenni finds out what needs to be done to encourage more men to donate. Will this week prove a turning point in the political career of the Italian prime minister Silvio Berlusconi? He may have told a gossip magazine that he has never paid for sex, but now a group of Italian academics have written an open letter to the wives of world leaders asking them to boycott a forthcoming summit in protest at his sexist behaviour. Also, an editorial in a very influential Catholic magazine has suggested that his behaviour has been less than ethical. Will Berlusconi survive this latest scandal, or is this the beginning of the end?
