A Breakthrough in Growing Embryos

Scientists are excited about their findings after leaving embryos to grow past the normal moment they’d be implanted into a womb. There is a legal limit on how long you can allow an embryo to develop outside the womb, 14 days, but even that might soon change as scientists argue it should be extended so they can discover more.

It used to be up to a week that scientists would study a fertilised egg before it was implanted into the womb, but with the extra days scientists have discovered many things about the early stage of development which often results in developmental defects and failure to implant. So all this extra information that they’ve been able to glean should help them reduce infertility in the future.

embryo -a new organism in the earliest stage of development. In humans this is defined as the developing organism from the fourth day after fertilization to the end of the eighth week. 

foetus – a prenatal human (before birth) which is between its embryonic state and its birth.

Remember that at 24 weeks of pregnancy in England a foetus can no longer be aborted. Meanwhile Catholics believe that from the moment of conception a new life has been created and Muslims think that even though abortion is wrong if the mother’s life is at risk then up to 120 days the mother’s life has more value than the foetus.
