The process of bearing a baby is complex, but incredibly interesting. For nine months a full-fledged little man with his own characteristics and character develops from a small egg. Undoubtedly, this is a rather dangerous period for a woman, but it is in her power to make it so that the likelihood of complications is minimal. For this, first of all, it is necessary to understand how pregnancy proceeds by weeks, what features arise in the state of the mother and what stages of development the future baby is going through.
The secrets of bearing were always interesting not only to future mothers, but also to scientists. The first photos of the egg and the process of fertilization appeared in 1965. Later, scientists were able to take pictures that gradually reflect the penetration of the sperm into the egg wall and the subsequent division.
Of the two hundred sperm cells, only one can penetrate the egg and fertilize it. From this moment, we can assume that the process of development of the future man has begun.
