Implantation

Implantation is the process in which an embryo (fertilized egg) attaches to the uterine wall and begins to develop. This process is essential for a successful pregnancy, as the implanted embryo can obtain nutrients and oxygen from the mother’s blood supply. Implantation usually occurs six to ten days after conception, and if it is not successful, the pregnancy will not proceed. Implantation of embryos is a key step in assisted reproductive technologies, including in vitro fertilization (IVF) and intrauterine insemination (IUI). By understanding the physiological processes of implantation, doctors can better assist couples struggling with infertility and improve the success rates of assisted reproductive technologies.
