Women 38-40 and 41-42 years old have low live birth rates with low egg numbers.

How many frozen embryos is good?

Basically, if you are under 35, it's your first IVF cycle, your embryos look good, and if you have extra embryos good enough to freeze, we recommend two embryos to transfer.

How many eggs is a good number to freeze?

How many eggs survive the thaw?

As we've discussed before, the new form of freezing, called vitrification, is significantly more effective; studies demonstrate that 90–95% of eggs frozen using vitrification survive the freezing and thawing process (compared to just 61% of slow-frozen eggs).

Is 6 frozen embryos good?

We have found from our data that there is no difference in success between an embryo that is frozen on day 5 or day 6 which is very interesting. A recent study on slow blastocyst development suggests that day 6 embryos should be frozen and transferred in a later FET cycle rather than transferred fresh.

How successful are frozen eggs?

Currently women using their own frozen eggs in treatment have a success rate of 18% (30% with frozen donor eggs), which offers no guarantee of achieving a successful pregnancy and birth.

Are frozen embryos more successful than frozen eggs?

Thanks to modern science, about 90% of frozen eggs survive; meanwhile, about 95% of embryos survive. With frozen embryos, you have more opportunities to transfer fertilized eggs, which means you have a higher chance of pregnancy.

Is 5 frozen eggs good for IVF?

Women under 35 who freeze 10-20 eggs have a 70-90% chance of at least one live birth. If they undergo another cycle and increase the number of eggs frozen to 20, their chances jump to 90%

Is 35 too old to freeze eggs?

"Studies suggest that women who freeze their eggs before age 35 have a better chance of a successful pregnancy than those who freeze their eggs after age 35." This is because the more eggs retrieved and frozen, the better the chance of a successful pregnancy.

Should I transfer 1 or 2 frozen embryos?

Research shows that, for some women, transferring one fresh embryo followed by one frozen embryo, if a second transfer is needed, offers the best chance of having a baby without increasing the chance for twins.

Does transferring 3 embryos increase chance of pregnancy?

Transferring three embryos resulted in a lower birth rate than transferring two in the younger women and made no difference in outcomes in older women.
