In this event, unless the shell is otherwise opened or dissolved, the embryo will break through the shell. The next event for the hatchling to perform is called nidation, from the Latin word for nest. With implantation being successful, the hatchling will nourish from the mother's body and grow until ready to leave the nest - at birth. Little is known about the details of early human development. And one of the greatest problems facing conceptiatrics today is the high rate of conceptant mortality.
Mortality is highest prior to successful implantation.
Hatchlings can die struggling to implant, and some embryos fail to hatch. Conceptiatric medicine aims to solve these problems, by making conceptants healthy and strong. Today, reproductive medicine has evolved to include in vitro fertilization. In this procedure, the woman's egg is removed from her body and combined with her partner's sperm. The child conceived is then placed inside her body later, either in one of the fallopian tubes or directly inside the womb.
