Conception Date

Conception Date

The child’s life does not start from his birth, the child’s life begins from his/her conception date.

It is customary to say that the child’s age is being counted from the day of his birth. But this is wrong.

When the child is born, his/her age is not zero, it’s about 280 days or 40 weeks.

It is pointless to discuss when the baby comes to life inside mother’s womb, it does not become alive, because at the very birth it is already alive.

Child’s life after birth is not the beginning of anything new, it is only a continuation of life outside the mother’s body.

However, it is okay to determine the age of the child after the date of birth. This is definitely and universally accepted.

The true beginning of life – the conceiving of the child, almost never can be established with certainty.

The conceiving usually occurs somewhere between two menstrual cycles in the woman – during the period of ovulation.

If a woman has a regular sex life, it is impossible to say at what date she is exactly conceived.

The date of conception can be known with certainty only if the woman had one and only one sexual intercourse and then became pregnant.

Important to remember


Conception occurs during ovulation period at the moment when a female and a male sex unit are joined and fused – the egg cell and the spermatozoa.

In the middle of the woman’s menstrual cycle – about 2 weeks after the previous or 2 weeks before the next menstrual cycle, a mature egg cell is released from the woman’s ovary and travels through the Fallopian tube to the uterus for 2 to 3 days, then the egg cell is ready for fertilization.

This period is called the period of ovulation and lasts between 12 hours and up to several days.

If a woman has sexual intercourse in the period of ovulation and neither she, nor her partner have taken contraceptive measures to prevent the conception, then several million spermatozoa reach the uterus trough cervix – uterus opening.

They move in the direction and in order to reach to the released egg cell.

Many spermatozoa die on their way because of vagina’s acidic environment, but for conception only one spermatozoa is enough to fertilize the egg cell.

Interesting fact:

The sperm that enters uterus can survive for 5 days maximum before being disintegrated from the woman’s immune system.

More spermatozoa can not fertilize an egg cell, because after the penetration of the first one, it instantly produces an impenetrable membrane and prevents others from entering.

Important to remember


After the penetration of the spermatozoa in the egg, their cores fuse into one and their substances are merged, commencing the pregnancy of the woman.

Spermatozoa and the egg cell are carrying chromosomes that contain the genes – carriers of the characteristics of the woman and the man.

In the newly formed nucleus – the conception of the new life, each hereditary feature is represented with two genes, one of the man and another of the woman.

Sometimes one will prevail, another time, the other, but each inherited trait is the result of their combination.

If closely, in laboratory conditions (in vitro), we observe the process of fertilization, then we can  determine the exact date of conception with certainty.
