Conception

Conception is the moment that the sperm fertilizes the egg. The combination of the sperm and the egg is called the zygote.

The Prenatal Period - From Conception to Birth

The period from conception to birth is called the prenatal period and it is divided into three stages:

1. The Zygote or the Germinal Stage

It begins at conception and lasts about two weeks. During this period, the zygote gets divided into many cells, travels down the fallopian tube and gets attached to the wall of the uterus.

     
2. The Embryonic Stage

The embryonic stage starts on week two and lasts through week eight. During this period, the cells continue to divide and eventually lead to the development of the nervous system, the heart, the face, arms and legs, and many other structures.

3. The Fetal Stage

The fetal stage is from week nine until birth. During this period, all of the systems, organs and structures grow and become more sophisticated to a point that the fetus can survive outside of the uterus.
