Tom Cruise and Katie Holmes are reportedly seeking medical advice following a series of failed attempts to conceive a second child. The couple is desperate for a son following the birth of daughter Suri in April 2006, but Holmes is alleged to be having difficulty becoming pregnant. And the Batman Begins star is now preparing to visit a specialist at Cedars-Sinai Medical Centre in Los Angeles later this month (Jan08) to establish the problem. A source tells Britain's Now magazine, "She's really upset about it. The one thing she wants more than anything is a son for Tom. "She says they've been trying since the summer, but it just hasn't happened for them yet. "Katie and Tom sat down and had a heart-to-heart and decided it might be worth her going to see the doctor to get checked out."
