Six to 10 days after fertilization, the embryo attaches, or implants, itself into the lining of the uterus. During the next week or so, the embryo receives its nourishment and oxygen from the cells that make up the lining of the uterus. The two layers of cells become more pronounced.
What are the signs of successful implantation?
Some women do notice signs and symptoms that implantation has occurred. Signs may include light bleeding, cramping, nausea, bloating, sore breasts, headaches, mood swings, and possibly a change in basal body temperature.
What are the chances an embryo will implant?
Embryos from eggs of a 40-year-old woman had an implantation rate near 10-15%, while those from a 30-year-old had an implantation rate of 40-50%, according to national averages. The implantation rates can increase by genetically screening the embryos before transfer.
