4/29/2023 0 Comments Symptoms after fetI have gone through 5 failed embryo transfers, 9 embryos in total and not even a slight increase in bHCG, and I have only just found out that the embryos can actually fall out and the contractibility of the uterus is a very important factor in the whole process of implantation. Well, they can, and they often do! I have read several studies, and meta-study about possible use of tocolytics (oxytocin antagonists) in an attempt to decrease the contractability of the uterus – and they also say that increased contractions of the uterus diminish the chances of implantation. It’s strange that the doctors are not telling us that – I have been assured so many times that the embryos simply can’t fall out, but that’s simply not true. And these numbers increase for women with higher than normal contractibility of the uterus. That said, I don’t think this video actually proves that the uterus is not capable of expelling the embryos – if anything, it is demonstrating that the are actually very powerful contractions within the uterus that move the embryo around – and this patient is lying down! I have read several studies that showed that 25-50% of embryos are found outside of the womb, in the vagina, within 1 hrs of embryo transfer. I wish I could observe my embryo transfers in much the same way. It’s as if it cradled the the embryos for their implantation in a good spot! I believe it will help to know that implantation doesn’t depend on anything you can do or stop doing, and that once embryos arrive to our uterus, the endometrium is in charge of the rest… These findings downplay the importance of rest and support the early mobilization of patients after embryo transfer. It’s a waiting period that’s full of desire and hope that the embryos will implant, full of fear of failure and full of emotion. Additionally, this coincides with the most nerve-generating and emotional lability phase: the two week wait until the pregnancy test. This generates an added anxiety to the stress of not being able to rest as much as they’d wish. They’re afraid if they get up or make any kind of effort, such as going to the restroom, the embryos “will fall” they think they must be alert to keep them in the uterus. We tell them rest isn’t necessary right after embryo transfer or even during the days after, but they’re surprised by this fact and don’t pay much attention to us. In this video of an embryo transfer, we can see how the microdrop containing the embryos is moved from one place to another following different motion patterns: undulating, vibratory, slow, fast, and with rest phases.Īfter an embryo transfer, most of our patients feel guilty for not resting enough, especially when the cycle isn’t successful. The endometrium (the inner membrane of the uterus) has several motion schemes and during the embryo’s arrival phase, its function is to keep it in the uterine cavity, impeding its expulsion and implantation in inadequate areas. The study shows what happens to embryos when they get to the uterus, both naturally through the fallopian tubes and after an In Vitro Fertilization treatment through the cervix. This week we’re presenting a beautiful study in London, which has been awarded for being the Best Oral Presentation in the Congress and we would like to thank all colleagues that have taken part in it.
