Where is the fertilized egg implanted after fertilization?

The fertilized egg, also known as a zygote, is implanted in the uterine walls after fertilization. This occurs in the uterus, where the endometrial lining provides the necessary nutrients and a suitable environment for the developing embryo. The uterus is specifically designed for implantation and subsequent development of the embryo, allowing for crucial processes such as nutrient exchange and waste elimination to take place.

The walls of the ovaries, fallopian tubes, and cervix do not provide the appropriate conditions for implantation and gestation. The ovaries are involved in the production and release of eggs, the fallopian tubes are the pathway through which the egg travels post-fertilization but are not suitable for implantation, and the cervix serves as the passage between the uterus and the vagina, playing no role in the implantation process.
