The sperm moves along the fallopian tube toward the egg cell to fertilize it.

Photo of the egg.

Decisive moment.

Of the hundreds of millions of sperm, only one can fertilize an egg.

Genetic material is located in the sperm head.

After a week, the embryo begins its path to the uterus to attach to its walls.

In another week, the embryo will attach to the uterine wall.

Embryo for a period of 22 days. The gray area becomes the brain of the child.

By the 18th day, the heart begins to beat in the fetus.

At five weeks, the fetus has a length of 9 millimeters.

 In the photo a little face is formed, and the holes are future nostrils, mouth and eyes.

 The external cells of the embryo join the free surface of the uterine wall, forming a placenta through 

which the fetus receives all the nutrients.
