Answer from: Raúl Olivares, MD
The implantation does not take place immediately after the embryo transfer. It usually takes place between 24 and 36 hours we have transferred the embryo. What we do is that we gently release the embryos inside the uterine cavity, and then the embryos stay around there for these 24 to 36 hours. It’s quite common that patients ask us what they can do after the embryo transfer if that is going to have an impact on the implantation or not, in normal conditions not. For example, we request our patients to come with a full bladder, we let them go to the toilet after the transfer has finished, they can even travel on the same day the embryos are going to remain there because the uterine cavity is a virtual cavity, so there is no risk that the embryos may fall out after the transfer regardless of what you do. It’s a completely safe procedure, and it’s completely safe to start leading a normal life after a couple of hours.
Why do we recommend these two hours after the embryo transfer? It’s because they may help keep the uterus relaxed, and that’s the only thing that seemingly can improve the implantation rates. Basically, what we want is to keep this uterus relaxed until the embryo is implanted. If you want to take things easy for these 24 hours, that’s fine, it’s not going to be a problem, but it’s not strictly necessary.
In the end, we may think about what a woman does when she is trying to get pregnant naturally. I mean nobody spends one day at home after they have had sex just because they think that is going to improve the implantation rates. They keep leading a completely normal life, they even go to the gym, they may have a glass of wine and things like that if the embryo implants, it is going to implant anyway. Don’t get too stressed about what you can’t do after the embryo transfer and especially in the first 24 hours that you need that are going to pass before the embryo implants.
When is the implantation day - is it the same day as embryo transfer?
How long does it take for an embryo to implant? How do you know if the embryo has implanted?
