The natural conception

For a pregnancy to occur, a sperm must fertilize an egg.

The fertilized egg (called the ’embryo’) then implants into the lining of the womb, where it grows and matures until delivery time.

For most people, the above is all they know about conception.

In each monthly cycle, only one egg – as a rule – is released from the ovary during ovulation.

The egg is then picked up by the nearest tube where it awaits for a sperm to fertilize it.

If the egg is not fertilized, it gets washed away with the next period.

Let’s suppose now that a couple have sex during the woman’s fertile days.

During intercourse, the man ejaculates inside the vagina.

The ejaculate contains millions of sperm that begin their long journey towards the tubes.

They pass through the cervix into the cavity of the womb and then they reach the tubes.


But there are many obstacles to overcome during this journey.

And most sperm die during the journey as a result of the obstacles encountered.

Despite the fact that fertile men release millions of sperm through ejaculation, only a few dozen of them reach the tube containing the egg.

And when they finally get there, they begin to siege the egg to fertilize it.

In the end, a single sperm is enough to fertilize the egg.

Then, the fertilized egg (or ’embryo’ as we will simply call it from now on) travels in the tube in the opposite direction towards the cavity of the womb.


At the beginning, the embryo consists of one cell which is then divided into two cells and then into four and then into eight etc.

This takes place initially inside the tube while the embryo is slowly moving towards the womb.

When the embryo reaches 50-200 cells, it forms a blastocyst, which is an important milestone in its development.

The blastocyst then implants into the lining of the womb 5-6 days after fertilization of the egg.

In conclusion, the basic prerequisites for a natural conception are the following:

  • Ovulation occurs normally, so a mature egg is released and awaits inside the tube
  • The sperm is normal, so that it is able to reach the egg and fertilize it
  • The fallopian tubes are open and functional to allow the sperm to meet the egg
  • The womb is normal and allows for seamless implantation of the embryo
