More women are choosing to have their eggs frozen in the hope they'll be able to have children later in life, but experts say there's no guarantee it will help them have a baby.

At 32, Women of Influence CEO Carolyn Lawrence wants to wait to have a baby, but her doctor has told her she doesn't have much time left.

"I don't' want to have to miss the opportunity and wake up when I'm 37, like a lot of women that I have seen do. They have focused on their profession, they've waited until they were emotionally ready with their partner or with their career, with their financial situation, and then they have found that they haven't been able to get pregnant," she told CTV News.

She's going to have her eggs frozen, in the hope that the new procedure will help her squeeze motherhood into an already jammed life.

"Now I can take some of that pressure off and focus on what I'm doing," Lawrence said.

The procedure will take two weeks and cost $8,500. The eggs can be frozen for up to 10 years.

But some fertility experts say the technology isn't good enough yet.

"Right now, it's only estimated that about five per cent of all the eggs that have been frozen will result in a live birth. That's not good technology," Dr. Albert Yuzpe said.

Even so, the procedure gives hope to cancer patients like Anna McFayden, whose chemotherapy might have made her infertile.

"It could be the difference between us having a family and not -- a huge thing that could change our lives," she said.

Her doctors at the Pacific Fertility Clinic don't freeze eggs for convenience, though. People like Lawrence have to go to a clinic in Toronto, although interest is building in B.C.

But Yuzpe urges women to be wary of any promises that the procedure will result in children.

"It's not fair advertising to say, ‘We'll freeze your eggs and you can have a baby 10 years from now,' because there's no guarantee," he said.

Lawrence says the risk is worth it, because her career won't wait.

"You know what the risks are, I don't have my heart set on it, so I think that I'm just delighted that there are more options for me," she said.
