Worldwide, frozen embryo
transfers grew from 10% of all in vitro fertilization or sperm injection procedures in 1991 to 28% in 2010, the most recent year with worldwide data available.
Family resemblance: The Shepherd family with Ryleigh (centre) who became the longest frozen embryo
baby at MIS.
babies typically had a longer gestation period than those born from fresh embryos, the research also found.
14) Likewise, if couples choose to create frozen embryos
through the use of ART, they should consider entering into a pre-frozen embryo
agreement prior to the medical procedure, addressing what would occur to the frozen embryos
in the event of divorce or other circumstances.
3) While it is clear that such surplus embryos exist in Canada (although the numbers are much lower than is often suggested, simply because many frozen embryos

The Johnsons decided to adopt a frozen embryo

Since the EAB rejects the position that an embryo is a moral person, it is not likely that it would regard the frozen embryo

Some suggest that frozen embryos
be viewed as property.

In concordance with research at CCRM, studies from around the world have shown that IVF pregnancies following a frozen embryo
transfer are more similar to natural conception pregnancies than fresh embryo transfer cycles resulting in:
Children conceived by frozen embryo
transfer are significantly more likely to be large for gestational age at birth than those conceived naturally or by fresh embryo transfer.
transfer (FET) involves the implantation into the womb of embryos that have been frozen, stored and thawed.
BABY Ryleigh may be only five weeks old - but she is actually a triplet to her two 11-year-old sisters - as she was a frozen embryo
for more than ten years.
However, the problem with the frozen embryo
technique was that it could not be used in certain cases, such as for unmarried females undergoing chemotherapy or even due to religious or legal issues," said Dr Radi.
