First baby from lab-matured egg
This post has been updated with another news story on the topic of egg-freezing
The first baby created from an egg matured in the lab, frozen, thawed and then fertilised, has been born.
Until now it was not known whether eggs obtained in this way could survive thawing to be fertilised.
The advance spares women from taking risky fertility drugs that can cause a rare, yet deadly condition - ovarian hyperstimulation syndrome (OHSS).
Canadian researchers told a fertility conference in Lyon three others are expecting babies by the same process.
The findings hold particular hope for patients with cancer-related fertility problems. More
2nd news story: Egg freezing boosts baby chances
Freezing can damage eggs. A new egg-freezing technique could give women a better chance of having a baby when they are older, say scientists. Freezing and thawing eggs has carried a high risk of damage, and of 153 treatment cycles in the UK between 1999 and 2002, just one baby was born.
The new Japanese-developed technique offers a ten times higher chance of a successful pregnancy. Using an antifreeze method, it has led to 11 babies being born, a European fertility conference was told. This technology opens up new horizons for medically assisted reproduction in women
The new technique offers hope to women whose fertility may have been damaged by cancer - and those who decide to put having a famly on hold. More

I would think that this technique might also allow women to freeze their eggs when they were young and at their most fertile, and to thaw them years later, when they were ready to have children, avoiding some of the problems that can be associated with delaying pregnancies.
