It's not every day that four (yes, FOUR) related OBGYNS visit the show -- so, needless to say, our studio audience jumped at the chance to pick the brains of (triplets!) Dr. Joanna Bedell, Dr. Sara Bedell and Dr. Vicky Bedell, and their mom, Dr. Janet Gersten.

Let's face it, the difference between a good and bad day can often come down to the type of underwear you’re wearing. Being comfortable is half the battle, right?

Well, it doesn't help that there is an overwhelming amount of options these days. There are bikinis, boyshorts, hipsters, thongs and oh so many more. But as it turns out, when it comes to your health, it doesn’t matter which of those you choose -- as long as it has a cotton crotch.

That’s right -- Dr. Janet Gersten told Rach that the material of your panties matters more than the style.

"I think I got the best question," Dr. Janet jokes in the video above (check out the questions her three daughters answered below!).

We don't disagree, Dr. Janet!
