**So what happens now??**
So even though 25 eggs were retrieved, it doesn't mean all 25 were mature or that they will all fertilize. Typically the numbers drop off by a certain percentage and that can occur due to many various factors. Sometimes they put the eggs and sperm in a dish and let the sperm fertilize the egg naturally on their own. We are doing this with half our eggs, or 13 in this case being an odd number. The other 12 are being fertilized via ICSI (intra-cytoplasmic sperm injection), where the embryologists select a single sperm to be injected into an egg, so fertilized by hand in a sense. ICSI ("Ick-see") can be helpful in certain cases where sperm might have some issues, or if it's frozen. Using a donor, that's the case for us. Even though donor sperm "should" be super sperm, it doesn't mean it is perfect. In case there is some issue with it that we don't yet know, ICSI is kind of a way to give them a boost and help fertilization along. So again, not all will fertilize and we expect the 25 number to drop off a bit. We will hear tomorrow and that magic number will determine a day 3 or a day 5 embryo transfer. If you have less than 3 or 4, they do a day 3. If you have 4+ they do a day 5. Day 5 is optimal but it depends on the count. Day 5 allows them to grow and develop more before putting them back in. What happens either way is whenever they decide, we will go back for an embryo transfer. I'll be in the same room right next to the lab and they'll insert an embryo into my uterus, via a small catheter. In a way it's exactly like the IUI procedures I had done, but the embryo is going in rather than a vial of sperm. All the embryo has to do is snuggle into my uterus and stay put! Then you wait and hope for the best! The remaining embryos will be frozen and if it doesn't work this time, we can do a frozen embryo transfer (FET) in another month or so and it's the same thing but no need for another egg retrieval unless we run out. If this cycle works, we save any frozen embryos for future siblings and repeat the FET with them down the road. Praying and hoping we are done with the initial IVF steps and that this batch of eggs will get us the family we've been dreaming of!
