Multiple pregnancy at all times was considered an unusual, truly wonderful phenomenon. Even in the modern world, people born as a result are enjoyed by the surrounding attention. After all, the twins are not only often similar to each other as two drops of water, but also have a special connection, which is formed between them even during the period of intrauterine development.
Scientific studies have shown that many twins communicate with each other at the 14th week of pregnancy: staying in the maternal womb, each of them tries to get close to her twin, stretching the handles to him. After 18 weeks gestation, gesticulate, touch and stroke each other. For such communication, the twins pay about 30% of their time.
There are cases when, when conducting the first ultrasound research (ultrasound), doctors are determined by two embryos in a pregnant woman's uterus, and report the future mother that her pregnancy is multiply. However, during the second and third ultrasound, only one fruit is determined in the uterus.
The reasons for this phenomenon can be stress and nervous overvoltage, leading to spontaneous abortion of one of the embryos in the first trimester of pregnancy, as well as the absorption of the tissues of one twin by the second twin, the placenta or the uterus.
Approximately every 13-16 years in the ovaries there are maturation of several (most often two) eggs. If during this period a woman will enter into a sexual connection with two different men, she can conceive children from each of them. The probability of conception of such twins is extremely small, and is approximately 1 to 400.
If the spouses who are mulatto or representatives of individual races will decide to become parents, then twins can be born with different skin color. In this case, to have absolutely identical physique and face features.
Toxicosis subsides, well-being is improved. The second trimester of pregnancy for the future mother of twins is one of the most favorable periods. The kids grow rapidly, develop and still behave quietly, but soon you will feel the first movements.
To take pregnancy at double - a difficult task for a woman, since the load on its body increases significantly. Multipletic increases the risk of developing the health problems of the future mother, increases the likelihood of such complications, as a frozen pregnancy, miscarriage, premature birth. That is why this condition requires increased attention from the medical personnel.
Early diagnosis of pregnancy with two fruits, or double is crucial for its further flow. Usually a woman does not notice any special signs of pregnancy twins in the early stages. Most often, the situation is clarified during the first ultrasound.
Ultrasound, spent on an early term, does not always confirm the pregnancy of twins, since when examining one fruit may well hide after another and remain unnoticed. This method will be informative with 8 weeks of gestation, when two heartbeats will be brought.
Pregnancy test, made when double, may also indicate that two or more embryo develops in the uterus. In this case, the second strip on the test, testifying to pregnancy, will be brighter and clear.
The reproductive system of man is very economical, and usually a woman becomes a mom of one kid. Nevertheless, occasionally we come across parents, walking with a double carriage or tricing in a car of two completely identical carapaus. Why is this happening? What is the likelihood of becoming a mom of twins? What awaits a woman when it comes a double time to appear - caesarean cross-section or natural childbirth? We answer your questions.
Sometimes two or even more babies begin to grow in the womb of the future mother. If you do not consider unique and very rare cases, then the twins can be homozygous (single-line, which appeared from one egg) and heterozygous (multi-sized, grown out of different eggs).
Heterozygous twins appear if a woman simultaneously matures a few eggs. The kids are always separate - each of them has an individual placenta and a fruit (amniotic) bubble. They may have a different floor, and, in general, they are usually similar to each other no more than the children of this couple, born with an interval of several years from different pregnancies. At the same time, the eggs can be fertilized both as a result of a single intercourse and different - with an interval of several hours or days.
If a woman leads a very active sex life, even such a situation is possible, when one egg fertilizer is fertilized with a sperm of one partner, and the second one. Then, at birth, kids appear twin, each of which has their own father, which is called the term "superecondation" in the scientific language. The exact frequency of this phenomenon is unknown, but in cases where DNA expertise was carried out in challenging paternity (in other words, when potential dads suspected in advance that the case was unclean) Superfucration was confirmed in 2.4% of the twins pairs.
With monosic twins, another story. First, everything is happening as usual: one egg cell is coming out of the follicle during ovulation, it is fertilized with one spermatozoa, becomes one zygote (a cell with a combined genetic material of parents), from which one embryo should develop. But after a while, it is unexpectedly divided into two identical copies. One of them can be divided repeatedly, and then instead of childbirth twin mom, the triows are expected, if they do both zygotes - twins will already become four.
Not harming his health and life of future kids, a woman can make a maximum of 6 children at the same time. In Africa, there are a lot of pregnancies at once in several fruits. And very rare cases of multiple pregnancy in eastern countries - Japan and China.
- Ta, in which the feet of a woman occurs simultaneous development of two and more fruit. There are various classifications of such gestation. By the number of fruits, multiple pregnancy (MB) is:
twins can be a diverse, and this is most cases, about 70 out of 100, according to statistics. How is the gestration of this type formed? In the ovary at the same time, the maturation of two eggs occurs. They are encountered with spermatozoa or for one subsidement, or for two. But the period between these acts of conception should be no more than one week. In such cases, you can conceive multi-two twins from two partners. An example can be found in the movie called "Cuckoo".
What is the difference between? The first genes are the same, because their appearance is very and very similar. The diverse kids can only be slightly similar (the relationship is visible, but there is no complete resemblance). Gemini, who appeared from one egg, always have one sex (either both boys or two girls). Twins from two eggs can be different floors.
The multi-mb is also characterized by a separate placenta and shells for each of the fruits. The second name of such a gestation is a biocherial biamniotic. If the pregnancy is one-way, the division occurs after the process of fertilizing it with spermatozoom. Twins are arguing if the division of the fertilized egg occurs after 12 days. Perhaps such a battle:
If in the family (in the family) there were already rays of the twins, the probability of MB is many times more than other families. Doctors noted that in such families the birth of twins happens through one generation. That is, if your grandmother gave birth to twins, then MB can be with you.
Twins - from the word "close", the one who is next to birth. In countries with developed reproductive technologies, they are no longer surprised - look at the photos of Children of Scandinavia: the mass of the same blond kids! However, the reasons for the appearance of twins and twins are not only in Eco. Medaboutme offers to calculate your chances of twins: scientists managed to find out what boosts the likelihood of "double happiness".
The name of the children who appeared on the world at the same mother at the same time. Surprisingly, the father's fathers can have different men! All because for the emergence of such children you need two (or more) matured eggs.
Each of them requires sperm - and after fertilization, embryos begin to grow. Since genetic sets in eggs and sperm cells are unpredictably different, can be very similar or not at all like each other.
Inadentic twins can be a one-sex or "royal couple": a boy and a girl. The main reason for the appearance of such kids is the peculiarity of the parent organism, in which in the same cycle in the ovary matures more than one egg cell. So it can occur due to hereditary tendency or under the influence of various factors. And some of them can be controlled!
Identical twins that are called twins, appear from one egg and one spermatozoa. In 3-4 cases, from a thousand, a fetal egg is not just growing, and in the process is divided into two parts (extremely rarely - three or four).
Since the chromosomal set of everyone is the same, then the children are born indistinguishable, and always same-sex. However, Identic twins can be "mirror" transformations. Most often - Moles from different sides and left-hand: every fourth twins - left-handed. But there may be a complete transposition of organs, when the heart on the right, and appendix left, and everything else is "not so."

One of the undisputed signs of pregnancy is the increasing belly. Why and how does it grow? It would seem that the answer is obvious: the belly is growing because a child is growing in it, and this happens to all future moms equally, because any normal pregnancy lasts 9 months.
