Unlike with fertilized egg freezing (embryo cryopreservation), egg freezing does not require sperm because the eggs are not fertilized before they are frozen.

What if, instead of trying to prevent a disease – or attempting to cure it – it could just be eliminated, before birth? Surely the world as we know it would change forever, in practically countless ways?

One of the latest breakthroughs in science involved the editing of genes in a human embryo to safely remove a dangerous mutation which results in heart disease.

Some researchers and experts believe the procedure could one day be...

Fertilisation of the egg by the sperm occurs within the Fallopian tubes during a natural conception. The fertilised egg travels along the Fallopian tube to get to the uterus for implantation on the 5th day after fertilisation.

It has increasingly been shown that implantation rates and hence pregnancy rates are much higher when embryos are cultured to the fifth day before transfer in an IVF treatment cycle.

The risk, of course is t...
