To kick start this new series of The Fertility Podcast, Kate is joined by a returning guest and friend of the podcast, Lucy Lines. Lucy is an embryologist in Australia, she is also a fertility educator and advocate. On today’s episode, Lucy is chatting all about embryo grading and what it is and how it’s done. Lucy explains how to grade an embryo and how a decision is made on which embryo to transfer. Lucy then delves into what it is like to be an embryologist, talking about the training period and the subjective nature of grading embryo’s and how this will differ from one embryologist to the next. Kate and Lucy move on to talk about which day post collection an embryo should be transferred. Lucy tells Kate that there is a lot of debate around whether day 3 is the best day or day 5 is. More often than not, clinics will prefer to transfer on day 5, as it usually has a higher success rate than day 3 and there are interesting reasons as to why this decision is actually made…….. Lastly, Kate and Lucy talked about batching and what to do if you are thinking about batching embryos. Lucy’s answer is that there is a lot to take into consideration when thinking about batching. Considerations with regards to your age, your AMH, the stability of your relationship with your partner and what to do with the frozen embryos when you have completed your family.  A little bit of advice to take with you from Lucy is when choosing a fertility clinic, take a look at the live birth rate per cycle, how many women who started a cycle ended up with a baby? And, a question to ask at you appointment is how far below the threshold would they grade the embryo?
