Fertilization, detection of pregnancy, fetal development
How to get fertilization? Where do you get?
After the start of the egg from the ovary, in the middle of the menstrual cycle, is located in the abdominal cavity Vinjzb the uterine tube grasped by the tip "lacinate" and directed toward the uterus by Ohadabh small cells of Interior, which tend from outside and towards the inside, also tends field of soft green grass. And when they arrived to the center of the tube, intercepted sperm masculine, which may be reached in advance to the uterus after the sexual relationship. Vindf forward towards her and nodded Anthaa and invaded to unite them and melt them updated so fertilization.
I've spent the wisdom of the Creator in his creation that the sperm cell and one out of about three hundred million sperm cells become able to fertilize an egg, therefore, we find that 99% of women give birth to one child, while the twins come from vaccinated Bweidtin Nadjtin during one menstrual cycle. The remainder of the sperm cells Vtamot gradually in the fallopian tubes, uterus and abdominal cavity, and can be for some to live more than a day or two if it is found in the folds of tissue temperature and kept her life. Studies have shown that about 2,000 medical sperm sperm only up to the tube and swim toward the egg for fertilization of sperm out of 300 million sperm a normal rate and when the man is required for fertilization.
What will happen to the fertilized egg in the tube?
Pass through the canal fertilized egg to the uterine cavity of the uterus to instill in the wall. This requires cutting the distance of about four days, a sufficient duration required in order to prepare the uterus to receive the same fertilized egg, and so the body begins to yellow - the custodian to secrete the hormone progesterone Hml- in the blood and is necessary to support and nourish a pregnancy.
Are nesting egg in the uterus, in general, after seven or eight days after its launch from the ovary, or rather premenstrual next seven days ago. For this reason, you can not carry that continue to evolve without the activity of the body, yellow, and if the ratio decreased hormonal substances secreted by the latter in the blood Event abortion early pregnancy, therefore, doctors, in such cases, to examine the urine of women abortionist to know the amount of the hormone progesterone as well as estrogen , and determine the reason for this shortage.
Fetal development and growth
Life begins with small cell, which will consist of them inside the human uterus, the egg is divided into two cells divide completely, then divided Alkhlitan two to four cells, then eight, and so on .... until the circle is composed of living cells resemble normal berry fruit, and is divided circle turn: an outer layer, a feeder layer that breathes and feeds through the fetus, and the inner layer, the layer that is made of the embryo itself.
Ontogeny months months.
In the first month:
You get an egg on the fountain of life once Ingrazha in the womb. In the first week, and from that moment onwards, take lying down and grow up to become a mass the size of the point to the fetus, and later to a big baby is made up of billions of cells.
In the fourth week of the first month:
Fetus grows by leaps and bounds Faisal length of 20 millimeters, and become fertilized egg the size of an egg bird bath almost, at this time all the internal organs, such as the heart, liver, gastrointestinal tract, brain and lungs, has taken shaped actually, begins the heart does go on, but not be able to hear Dqath only after this stage several weeks. At this time the mirror may also be suspect began in the possibility of being pregnant at this stage are the advantages of the fetus may Genetic Thighs They started Stmisah from the other millions of people.
In the second month:
Become the face of the fetus generally similar rights. And formed his hands and fingers and legs, and can, at this time, seeing the first signs of the external genitalia and then begins to be bones.
In the third month:
Separated from each embryo fingers and nails begin to appear and disappear tail and bulging stomach. At this time begins with the mother's abdomen to inflation, as the fetus begins to feel weak moves by the mirror. In this month of pregnancy can be identified by the presence of the fetus by ultrasound (Ultrasound) or hear the heartbeat device ripples by ultrasound.
In the fourth month:
Weight of the fetus becomes a hundred and twenty grams and length of sixteen centimeters. Clearly characterized by sex and grow his hair and it shows. However, if the baby was born at this time would not be possible for him to live. Starting this hair back pregnant almost to normal and no longer feel vomiting, nausea and other symptoms of pregnancy core. In the end, may feel a few mothers fetus moves, but most of them do not feel so.
In the fifth month:
Fetal weight rises to three hundred grams becomes a length of twenty-five centimeters. This month, the mother feels the movements of the fetus. And keeping the history of these movements is important in order to calculate, more accurately, the expected date of birth.
In the sixth month:
Becomes a fetal weight of more than four hundred grams and increase the amount of hair on it. Even if the baby was born at this time was able to breathe freely, but can not survive more than a few hours only.
In the seventh month:
The weight of the fetus kilograms and half kilograms. If under the age of twenty-eight weeks, the likelihood of survival if born, have little medical aid without a high-placed in the incubator electric.
In the ninth month:
The average weight of the fetus becomes about three kilograms and a length of about fifty centimeters, which this month is preparing to go out to the new world shall be all members of the family waiting for him.

1 medical examination:
The first way
The greater the growth of the fetus and the large size of the uterus and dilate the large size also. The doctor can note this stretch by a medical examination by touch, vaginal, or by measuring the level of the uterus above the belly.
The second way
Which resorted to the doctor to confirm the pregnancy, is hearing the baby's heartbeat, either by regular medical ear, or using an electronic device works on the system (DOPPLER) whereby the doctor hears the heartbeat of the fetus and hear of the holder as well, starting from the eighth week of pregnancy.
2 test pregnant Paul:

The has become this "examination" is sold in pharmacies widely because women do not Ihtmln wait several days after menopause, bringing the rate of pregnancy hormones in the urine.
3 Acoustic Imaging (Ultrasound):
Can detect the presence of pregnancy in the beginning of the formation of the fetus by ultrasound device (Ultrasound) - also called Sonowerev - who works in a manner ripples or ultrasound vibrations.
The duration of pregnancy and birth date
The average duration of pregnancy when the mirror Two hundred and eighty days, or nine months, solar, or ten lunar months (the lunar month of 28 days) and that if we calculated the duration of pregnancy from the first day of the last menstruation or menopause. This calculation is an approximation may increase or decrease from that for a week. In 15% of cases occur before birth date theoretical week, and a similar proportion occur after the date the upcoming week or even two weeks. It appears that some children need a longer or shorter period for the specified time, inside the womb, for their full development.
Calculated by reference to the day of birth back three months from the date of the first day of the last menstrual period, and then add it to seven days.
For example:
Suppose that the last menstruation began when pregnant in the first of the month of September (September). Resurrecting the back three months to the first of any month of June (June) and add it to seven days, so the date of the governors at this pregnant, roughly in the eighth month of June.
