Natural Fertilization (Conception)

A stunning 3D medical animation showing natural fertilization. Fertilization is the epic story of a single sperm facing incredible odds to unite with an egg and form a new human life. The sperm's journey is visualized with rich detail and narrative to convey a fresh understanding of a classic physiological tale.

Shown at a cellular level magnification, sperm struggle through many obstacles in the female reproductive tract to reach the egg. Visualized at the molecular level, genetic material from the egg and a single sperm combines to form a new human being.

The chosen egg has taken months to gather all of the proteins, DNA and energy producing powerplants (mitochondria) that is needed to create an embryo should fertilization occur. Finally it is released from its follicular sac.

It is picked up by the fimbria and enters the fallopian tube on it's journey to the uterus. While in the fallopian tube it is met by the many sperm that compete to gain entry. Only one sperm will be allowed in. Fertilization occurs as the sperm DNA is released.

Over the next 4-5 days an embryo continues to develop in the fallopian tube on it's continued journey to the uterus. The cells continue to divide until a blastocyst has developed. It reaches the uterus and finds it's home in the uterine lining and implantation occurs. This is natural conception.
