Welcome to LWC Cardiff

At the heart of our state-of-the-art central Cardiff laboratory is something we call Precision Embryology. Our team use the latest techniques to give you the best chance of a successful IVF outcome, including time-lapse monitoring, embryo freezing, and genetic testing. Meaning you’ll get the best possible chance of having a healthy baby. Find out more today.

What is Precision Embryology?

The success of the LWC Cardiff laboratory has been due to Precision Embryology. We have two time-lapse incubators and over 98% of our patients’ embryos are cultured using this technology (fresh and frozen). Pictures are taken of the embryos every 5 minutes without disturbing their environment, so we can easily track their development. We can then freeze or transfer the embryo at exactly the right time.

Based on the precision embryology principals, the Cardiff laboratory have achieved very high standards.   On average 70% of the embryos we create make a blastocyst (a day 5 embryo).  If a patient has 4 or more fertilised eggs, more than 50% of the time the patient will have an embryo to transfer AND embryos suitable for freezing. This means patients treated at LWC Cardiff will achieve a high cumulative pregnancy rate by using their fresh and frozen embryos from one egg collection.

What is Precision Embryo Transfer?

The latest time-lapse technology in the laboratory helps our team of highly-skilled embryologists to decide the best time for embryo transfer. Viewing embryo development allows the embryologist to confirm whether to transfer on day 5 of embryo development or to freeze the embryo for transfer in a later frozen embryo transfer cycle.  This means that embryo transfer will be individually tailored to the patient to maximise success to you specifically.

This philosophy is different from standard embryology practice where embryos would be routinely replaced regardless of their development. Patients will also benefit from having a personal consultation with their designated embryologist to review the images of each of their embryos and to pinpoint exactly when the transfer will take place.
