Frozen embryos 'boost for IVF'
Frozen embryos are more likely to produce successful, complication-free IVF pregnancies than those that are fresh, research suggests.
IVF study finds frozen embryos better
- Frozen embryos are more likely to produce successful, complication-free IVF pregnancies than those that are fresh, new research suggests.
- Scientists made the discovery after analysing data from 11 international studies involving more than 37,000 IVF pregnancies.
- In some cases, newly conceived fresh embryos were used. In others, embryos that had been frozen and stored for two to three months were implanted.
- Standard practice is to choose the best embryos for fresh transfer, and only freeze those of good enough quality that are spare.
- But the new results suggest it might be wise to freeze all embryos.
