Embryo transfers are exciting yet nerve-wracking! After this, an embryologist monitors the development of these embryos over a couple of days (usually day 5 also known as a blastocyst) and then choose the most healthy and developed embryo among them for the implantation or freeze them using the technology of Vitrification.

With IVF, many stages of preimplantation embryo development happen in a … After an embryo transfer, the precautions you take play a very minor role in whether you become pregnant. Embryos with uneven cell size have lower implantation and pregnancy rates and are more likely to be chromosomally abnormal (Hardarson et al. While the process sounds simple, there are multiple factors that can stop these steps from happening, such as a low sperm count, a compromised or blocked fallopian tube, a damaged or diseased uterus, or suboptimal egg production or quality. The resulting embryo must be of good quality in order for implantation to occur. Implantation is the process where the embryo attaches to the uterine lining (endometrium) and embeds itself into the tissue.This happens around Day 5 or so of the embryo’s development. I recently did a frozen embryo transfer cycle and I was nervous, anxious, happy, and excited all at the same time. 2001 ).

Hatching the embryo through the Zona Pellucida is an essential step preceeding implantation and involves both chemical and mechanical reactions, which eventually lead to thining followed by rupture of the Zona Pellucida. The embryo then compacts into a contained cluster of cells. Healthy embryo implantation is one of the key factors that determines successful procreation. Repeated or recurrent implantation failure (RIF) is detected when good quality embryos fail to implant after several cycles of In Vitro Fertilization (IVF).

The importance of endometrium on embryo transfer. However, if the doctors see that the combination of the correct implantation window, good uterus lining and genetically normal embryos does not result in a positive pregnancy test, it is time to move on to egg donation. The causes of implantation failure are most commonly related to the embryo or blastocyst. In IVF, implantation rates once were highly dependent on the age of the female who provided the eggs, as egg quality declines rapidly with age. On about the 7th day, the cluster of cells hatch and the embryo is ready to implant itself in the uterus. In the “fertilization” phase of IVF, many eggs are fertilized. The embryo is loaded into a catheter, which is passed through the vagina and cervix and into the uterus where it is deposited. Implantation of the embryo is the attachment of the embryo to the endometrium (lining of the womb).
