The birth of a new life is a touching, surprising, and fantastic process, Pregnant women, however, have always been interested in the question of how the conception and fertilization process is done.
Fertilization Process: From The Ovum To  Baby

Fertilization process: from egg to baby

Two small autonomous cells that combine and create a new person And when the time when the fetus begins to move is more or less tangible for the pregnant mother, then the first days and even weeks of pregnancy remain "behind the scenes". 

Fertilization by men and women:

A man can get pregnant every day if he is healthy In other words, sperm - male germ cells - are always in "full alarm" But in the fertilization of the woman is only possible on certain days of the menstrual cycle After the end of the next menstruation begins the maturation phase of the follicle.

Thus, different follicles mature in the ovaries of women, but only one or in extreme cases only one or in extreme cases two become dominant So, towards the middle of the cycle, the size of the dominant follicle is close to 20 mm, which means that the egg inside is ripe and ready to go. The time of follicle frace is called ovulation.

Finally, in women, this day comes after the duration of the menstrual cycle on different days, if 28 days usually range from menstruation to menstruation, ovulation should be planned on the 14th when the 30 days, day 15 pass.

Fertilization process:

Fertilization is a complex process that consists of several steps, including:

1) Determination of ovulation to increase the chances of successful fertilization.
2) Sperm in the female genital area.
3) A fusion of gametes with the formation of a zygote.
4) The movement of a fertilized ice from the fallopian tubes into the uterine cavity.
5) Fixation and implantation of the embryo in the thickness of the endometrium.

The time in which it should be fertilized is through the life cycle of gametes The egg is able to take sperm within 12-24 hours, sperm can be inactive state in the body for seven days, therefore the determination of ovulation time is important for the success of fertilization.

The time of fertilization!

After sex, a sufficient amount of sperm enters the woman's body Not everything in the uterine cavity, uterine mucus of the cervix delays a lot.

1) Sperm enters the opium sopies, and an egg awaits them, ready for fertilization.

2) Due to the special secret in the female genital tract, the acrosomal membrane is the week and allows sperm to penetrate into the egg.

3) To destroy the protective membrane from the onslaught, the sperm separates the hyaluronidase enzyme.

4) After all, barriers have been destroyed, the gametes are merged.

On what day does pregnancy occur after ovulation?

The time of pregnancy is determined by the life of ice and semen, as well as the time of sexual intercourse.

If the eggs leave the follicles on the day, the pregnancy should occur within one week, if the sperm enters the female body a few days before ovulation, fertilization takes place 3-4 days after the release of the ice.

Design-friendly time:

The most favorable time for fertilization is the day of ovulation, the egg remains vital for 12-24 hours, sperm for about a week.

Male germ cells can enter the body a few days before ovulation and maintain their ability to fertilize so that the week before the release of mature ice and the next day is considered a favorable time for conception.

Ovum Fertilization Time:

The period of ice fertilization is determined by the period of its vitality after the mature egg leaves the follicle, the germ cell retains the ability to fertilize for 12-24 hours. During this time, the sperm must penetrate into the egg, if this does not happen, the egg ends its life cycle, the next opportunity of conception will come in a month.

Changes in the body after the fertilization process:
Immediately after fertilization of the ice, a large-scale operation is started into the body to create new conditions that are more optimal for the development of a new life, in large quantities the body begins to produce the hormone progesterone. Their task is to loosen the walls of the uterus so that the embryo can easily fix at one of them and "grow" in the tissue. 

This place then becomes the base of the placenta.

Under the influence of progesterone, from the first minutes after conception, metabolic processes begin to proceed somewhat faster, Of course, a woman will not be able to feel these changes, in any case, in the first couple of weeks after fertilization.

Fertilization process symptoms :
