If you could stop the clock, would you? Well, according to the Royal College of Obstetricians, a new freezing technique called vitrification means that eggs can be frozen in time and stored indefinitely without deterioration. This development has prompted the government to debate an overhaul of fertility regulation intended to help prospective parents, where the 10-year limit on freezing eggs (as well as sperm and embryos) will be scrapped and raised to up to 55 years. In theory, this would mean that women who had their eggs frozen at 25 could have them de-thawed at 80.
