Abstract
This is a collection of all of the identifiable and stageable embryos collected over a period of years in the Department of Obstetrics and Gynaecology, Edinburgh. Each of the embryos has been allocated to one of the Carnegie stages on the basis of the maximum number of its developmental parameters fitting into the stage. Some embryos may have developmental events which could classify them into another stage, but using a rigid classification system would mean that some embryos are therefore not classifiable.
Keywords: Carnegie stages/development/embryo classification
