The F Word

Can food affect a man's fertility? Currently there's speculation about a general decline in the sperm count and whether it can be linked to diet. Gordon blames his own low sperm count on the fact that chefs are constantly exposed to high levels of heat during long hours in a kitchen environment. He enlists the help of a fertility expert and a clinical embryologist to see whether they support his theory and offer advice on how men can help prevent problems with their sperm. Plus top model Penny Lancaster comes for dinner and tells Gordon about her very fertile relationship with Rod Stewart.

Chat show maestro Jonathon Ross, is put to the test by Gordon this week when he's challenged to kill and cook lobster. 'If Paul McCartney is watching this, I apologize'. 'If you've got the bollocks to eat it, you should have the bollocks to kill it', responds Gordon. The show also features Gary Rhodes, an amazing report about the potential benefits of horse milk and an exclusive report on which is Britain's healthiest supermarket.

England Coach Sven Goran Erikson's partner, Nancy Dell-Olio, gives Gordon some tips on how to score when she visits The F Word. "The sexiest room in the house? It's the kitchen because the other places are too easy!'" Nancy cooks for and with Sven regularly, "I do the cooking, he helps me. We work together, we're a team.' Actor Richard Wilson - best known for his performance as Victor Meldrew - and Kim & Aggie from "How Clean Is Your House" take Gordon on with their trifle recipe; while resident food critic Giles Coren looks into the world of detox.

Writer and broadcaster Janet Street-Porter and former athlete Colin Jackson guest on the show devoted to all things culinary. Dishes on the menu include ravioli of duck, chestnuts with a Jerusalem artichoke sauce and a main course of sea bass. Gordon also reveals the secret of perfect roast beef and Yorkshire pudding.

The chef cooks a festive meal comprising truffle and herb buttered turkey with fried breadcrumbs for guests including Sharon Osbourne. The whole restaurant shares the Christmas feast rustled up from Gordon's hand-reared turkeys, aptly named Jamie, Nigella, Delia, Ainsley, Antony and Gary, while Hugh Fearnley-Whittingstall takes on the recipe challenge.
