00:06A major question for patients to ask is, what does success look like for me? Which can be just
00:11incredibly ambiguous because there is no quick feedback loop for egg freezing. Unlike with IVF,
00:17you just never know whether the results that you got are any good. How many eggs do you need to
00:22collect by what age to feel confident to get a live birth? I think this is a little bit where
00:28egg freezing is in its infancy. I don't think there's any magic answer. For a young patient at
00:33age 25, eight eggs, you know, should be a good number. If you just think about, you know, expect
00:40seven of them to survive and six to fertilize and then maybe three to develop into blastocysts and
00:48then two or all three of them to be normal and they have a good number of normal embryos to
00:52work
00:53with. Where at age 40, you might need 20 eggs, you know, if you want to have that same type
00:58of
00:58confidence because 18 of them may fertilize and then six or seven may make blastocysts and of those
01:04maybe only two are normal. What has been shown, if you're under 35 and have 20 mature eggs in the
01:11freezer, 90% of those patients will have a baby from those eggs. I would say it's an inverse
01:17relationship. The older you are when you freeze your eggs, ideally the more you want to have set
01:24aside frozen because we know statistically the quality of those eggs has gone down. A recent study
01:31looked at women who froze their eggs at different ages and later tried to use those eggs. First were
01:37women who froze eggs at 35 or younger. If they froze 15 eggs, 85% of them had babies. Of
01:45those women 35 or
01:47younger who froze only 10 eggs, 60% had babies. In contrast, a woman over the age of 35 who
01:55froze 10 eggs,
01:56only 30% had babies with those eggs.
