Transcript for 'Dancing' Star on Decision to Freeze Eggs
I'm in enough trouble. We're going to go with "Dancing with the stars" pro Karina smirnoff. She's revealing a personal decision facing so many young women who want a family but aren't ready to start yet. She's freezing her eggs. Reporter: For 17 straight seasons, professional dancer Karina smirnoff has dazzled on "Dancing with the stars." Topping the leaderboard is not the only thing on her mind. You have dreams beyond the dance floor. Absolutely. I thing it's natural for a woman to want to B a mother. Reporter: After her share of failed relationship, including one with fellow "Dancing with the stars" pro maksim chmerkovskiy, being a mother, let alone getting married seems a long way off. You've come close to getting married a few times? A few. Reporter: Not wants to miss out on mother hood, the currently single 35-year-old decided to freeze her eggs so use later when the timing is right and documented each pain-staking moment on video. You clearly are not a fan of needles. I'm afraid. I actually passed out. The very first one, it took me an hour to stick the needle inside. Ooh. Not a fan of needles. Reporter: Why did you decide the freeze your eggs? My profession is dancing. I've concentrated on my career for a long time. I love what I do. But I know I want to be a mother. Reporter: After 12 days of estrogen injections, she was ready for the egg retrieval. We're on the way to finally do the procedure. Reporter: How did her procedure go? It went very well. We stimulated her ovaries and got 21 eggs. Reporter: He says it's possible the frozen eggs could last indefinitely. But the chance to harvest them, finite. We like to do this ideally before a woman is 35. Reporter: You think in the end, it's all worth it? 100%. It's not easy. It's scary. It's something that, like, you know you're doing it for yourself. You feel empowered with the fact that you were able to give yourself an opportunity to not have to worry about your biological clock. Reporter: And you're one step closer to the family you have always wanted. I am. I'm one step closer. Reporter: For "Good morning America," Abbie Boudreau, ABC news, Los Angeles. Let's bring in Jen Ashton. Karina says 100% she would do it again. Is it viable? The arm, the big society for fertility issues said in 2012 egg freezing is no longer experimental. It can be elected. It's a very important technology for certain types of women. It's not the same as not doing this type of procedure. Again, it's not just going to be a convenience issue. This is for specific scenarios, certain types of women. Are there risks involved? Yes, sure. It's expensive. Medically, low risks of infection, bleeding. You can overstimulate the oafrioaf ovaries. We don't know yet both for the babies conceived with this procedure, and for the moms 20, 30 years down the road how things will turn out. A lot of people now with hope. Who should perhaps not consider this? This appears to be safe and effective. It has about 30% to 60% efficacy rates in all comers. The age of the woman giving the eggs is the most important thing. What this is really exciting for, women who have medical issues, who may be undergoing treatments for cancers. We're picking up a lot more cancers in preproductive-age women. If the woman is getting surgery or radiation to her pelvis, it's important. Not just for convenience. It's also really expensive. You have to pay fees to keep the eggs. It's incredibly expensive. It could be $10,000 for one cycle of tens of thousands of dollars. Thank you, Jen. I know WYOU want to talk to her about hockey, but --
