The F Word (2005)

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.
