Maria Menounos' plans for her embryos

Last week, entertainment celebrity Maria Menounos made news when she announced she plans to freeze her eggs for future use.

But in an interview with CNN, Menounos clarified that she's actually freezing embryos, not eggs. Fertility doctors will make the embryos by fertilizing her eggs with her boyfriend's sperm in a lab. The resulting embryos will then be banked until the couple wants to use them to start a pregnancy.

The difference between freezing eggs and freezing embryos is significant. Women who freeze their eggs usually do it because they don't have a partner and they're concerned their eggs will be too old by the time they find one. Menounos, on the other hand, has a boyfriend, writer/producer/director Keven Undergaro.

The host of "Extra," Menounos, 33, says she and Undergaro won't be ready to start a family for another four to five years. If they can't conceive naturally, they'll thaw out their frozen embryos and have them implanted in Menounos' uterus.

"Being a parents is the hardest job in the whole world, and I don't want to do it until I'm ready, and I don't feel ready right now," she says.

Menounos said the procedure will be videotaped and air on "Dr. Drew's Lifechangers" hosted by Dr. Drew Pinsky. She added that she may also freeze "an egg or two" if it would help illustrate the procedure to viewers.
