Where does a fertilized egg implant during normal pregnancy?

During a normal pregnancy, a fertilized egg implants in the uterus. This structure provides a suitable environment for the fertilized egg to develop into a fetus. The uterine lining, rich in nutrients and blood supply, is specifically designed to support early development stages after implantation.

The other locations mentioned are not suitable for implantation. The Fallopian tube may be where fertilization initially occurs, but if the egg implants there, it can lead to an ectopic pregnancy, which is a serious medical condition. The ovary is where eggs are produced and released, but it does not provide the necessary environment for a developing embryo. The cervix, which connects the uterus to the vagina, is also not designed for implantation and supports different functions in the reproductive system. Thus, the uterus is the correct site for implantation in a typical pregnancy.
