Do you remember why Clark asks Bernie to do the research? Was there some specific reason? Was that the episode where Lois freaks out about the nursery school reservation list? Clark askes Dr. Klein to do the tests after he and Lois have unprotected sex at the beginning of "Faster Than a Speeding Vixen" - after Lois "attacks" Clark in the kitchen.
In their conversation, Clark mentions that he's not sure if he *can* make babies and Lois suggests that he talk to Dr. Klein.
