This news article came out yesterday in The Guardian online, reporting on the use of multiple embryos being transferred into the uterus during IVF. The article focuses on a study carried out by scientists at the Leicester Infertility Centre.
A pretty interesting read, and gives the view that using a single embryo in the IVF process has just the same chance as multiple embryos for a healthy live birth, without the risks associated with multiple births, such as high blood pressure and pre-eclampsia. There is also a much higher risk of twins or triplets being born prematurely, leading to a risky start in life with the possibility health problems after birth and later on in life.
The article says how single embryo transfer should implemented in the UK, reducing multiple birth pregnancies, preventing health risks to the mother and child.
