What is time-lapse and how can it help you get pregnant?

Time-lapse is an old imaging technique, where a camera is set to take a series of images at regular intervals. This technology is now available for monitoring the development of embryos during IVF before they are transferred into the uterus.

After the egg is fertilised, it needs to grow for a few days before it is placed in the uterus. Not all fertilised eggs develop to good quality embryos, which reduces the chances of implantation and live birth.
Before this technology was available, the embryologist would look at embryos through a microscope and decide which had the best chance of developing into a baby.

Today, time-lapse, takes pictures of the fertilised egg whilst it’s developing in the incubator. The embryologist has access to these pictures on his computer and is able to identify embryo development potential. Instead of making a decision based on how the embryo looks at that one instant before it’s placed in the uterus, the embryologist uses thousands of pictures from the whole period of development which lasted a few days.

The technology allows the embryologists to select embryos with a lower risk of defects and/or greater potential for implantation.
