This success has been due to the Precision Embryology we have incorporated into the laboratory. When you compare the latest HFEA verified data in our region, our Cardiff laboratory comes top! The latest success rates from the LWC Cardiff laboratory show that we have achieved great success with our FET programme over the last 15 months. In Cardiff, FET cycles increased by 32% (2017 vs 2018) and we’ve already done 20% more in 2019 compared to the same time in 2018! How successful is a Frozen Embryo Transfer?Īccording to the latest HFEA national figures, FET is now more successful than a fresh embryo transfer. ![]() The fasted growing trend in IVF is egg freezing but for us FET cycles have increased faster than any other treatment. Has LWC Wales seen an increase in Frozen Embryo Transfer cycles? There has been a lot of research on this topic but at present there is still no consensus as to the best policy with different clinics favouring fresh or frozen embryos. More clinics are opting to freeze the embryos and replace them in an FET cycle a month later or when the patient is ready.Īn FET cycle uses minimal or no medication so one embryo can be replaced into a much more natural environment resulting in potentially higher success rate and hopefully a safer pregnancy. ![]() It could also reduce the chance of pregnancy. Due to the stimulation medication a patient is given prior to egg collection and the trauma of the egg collection procedure itself, an embryo transfer during this same cycle may not be the best or safest time. Over the last few years, the scientific community have found that embryo transfer in a frozen cycle may produce better results. For example, if you were aged 35 when you froze the embryos, if you use them 5 years later, the embryos will still be 35! This means that today embryos can be thawed out and replaced in a Frozen Embryo Transfer (FET) cycle, when the patient is ready, with the same or better chance of success than in a fresh cycle. Using the latest vitrification technology, embryos don’t deteriorate once frozen they are preserved at the age you are at the time of freeze. Traditionally, we then replaced the best embryo (or sometimes two) back to the patient on day 5 and freeze any remaining good quality embryos. The embryos are then cultured in the laboratory for around 5 days and closely monitored by a team of highly-skilled embryologists. The collected eggs are then fertilised in the laboratory using IVF or ICSI to create embryos. Why have Frozen Embryo Transfer cycles seen such an increase?ĭuring an IVF cycle we stimulate the patient’s ovaries before an egg collection procedure takes place. For the first time, Frozen Embryo Transfer cycles are now more successful than fresh (23 vs 22%) based on the HFEA’s national figures. According to the latest HFEA Trends and Figures report published in May 2019, Frozen Embryo Transfer (FET) cycles have increased by 11% between 20 whilst the number of fresh embryo transfers has dropped by 2%.
