A new life can start with the fusion of the sperm and the egg, which contains the genetic information of the father and the mother in equal parts. On the way through the fallopian tube, the egg cell divides several times. It finally gets lodged in the mucous membrane of the uterus, a special hollow muscle. This has a good blood supply and provides the egg cell with nutrients. After it is fixed in the uterus, the egg cell is called an embryo and development starts immediately.
