Frozen embryos better than fresh ones

LONDON: Frozen embryos are better than fresh when it comes to producing healthier babies using in-vitro fertilisation, a new study has revealed.

Researchers in Denmark have found that babies born from thawed embryos were heavier at birth and were unlikely to suffer abnormalities as compared to those born from fresh embryos.

“Only very top-quality embryos survive the freezing and thawing process. And you only get pregnancies in patients with lots of good embryos to freeze,” lead researcher Dr Anja Pinborg was quoted by The Daily Telegraph as saying.

The researchers at Copenhagen University reached the conclusion after comparing over 1,200 children who were born from frozen embryos between 1995 and 2006 to 17,857 infants who had been born from fresh embryos during that period.

Freezing embryos allows couples to have several in-vitro fertilisation (IVF) treatment cycles from the same egg collection, reducing the number of times that the ovaries are stimulated.

The eggs are placed in the womb three to five days after ovulation in exactly the same way as fresh embryos. Multiple births accounted for 27.3 per cent of children born from fresh embryos, compared with 14.2 per cent when frozen embryos were used.

Only very top-quality embryos survive the freezing and thawing process.

Starving and beating lead to healthier Jews, because only very top-quality Jews survive the starving and beating process.
