How can you get pregnant with Identical Twins? in this article we will help you to know how.
Where Identical (identical) twins occurs:
Identical (identical) twins occur when one egg is fertilized by one sperm (one sperm) so that a single fertilized egg (fertilized) is formed, later this fertilized egg divides into two parts and this division occurs during a short period after which each half of the egg grows and develops into an embryo Why do identical twins occur, what increases the likelihood of a twin pregnancy, and what are the problems with this pregnancy, this is the topic of our next article.
Overview of the genetic material in identical twins:
We must look at identical twins as if they are one genetically speaking person, because the two fetuses will be completely identical, because the division occurred after the formation of the fertilized egg, and this means that they have the same color of eyes and hair color, and if one of them suffers from a genetic disease, the presence of this disease must be investigated by the brother. . This means that we look at two children of exactly the same shape, but some strange cases may occur, for example:
Twins inverted images:
Inverted twins are simply the image of a twin in the mirror, when the egg is delayed in dividing (for example, it divides after a week or 10 days), the inverted twin can form, so that these twins are identical, but they are images of each other, for example their hair may be spiral in opposite directions, or Teeth may begin to form on opposite sides of the mouth, or one may be right-handed (use his right hand to write) and the other may be left-handed (he uses his left hand to write).
The conjoined twin (also called the Siamese twin) is one of the medical dilemmas, and it occurs because the fertilized egg is too late to divide and then may not be able to separate completely (this happens when the fertilized egg divides after 12 days of pregnancy or more). The site of fusion or attachment varies from one case to another, but it often occurs in the chest or abdomen, and twins may share one or more vital organs, making the separation process risky.
Many conjoined twins die after birth, and others require long, delicate, and difficult procedures, and the degree of difficulty involved in the operation depends on where they are attached and which organs they share.
Can identical twins be heterosexual?
The answer is no, since the twins have the same genetic material, and they are definitely of the same sex, because the genetic material determines the sex.
What Causes Identical Twins?
Although there are some factors that make non-identical twins more likely, such as an increase in women's height and weight, a woman's age, and other factors, the exact reason why this occurs is not completely known.
Do identical twins share a placenta?
Identical twins may share a placenta, and they may have two different placentas, depending on the day the division occurred. If the division occurs early before the egg implants in the uterine wall, two placentas will form, but if the division is delayed, one placenta will form and nourish the two fetuses.
What are the medical risks during a twin pregnancy?
In general, the pregnancy passes peacefully, but it needs careful medical monitoring, as complications occur in a twin pregnancy much more than a single fetus pregnancy, and of course the greater the number of fetuses, the higher the risk of complications and the most important of these complications:
Pregnancy problems: Some complications occur during pregnancy, especially in the last months of pregnancy, where pregnant women are exposed to high pregnancy pressure or high gestational diabetes, which is called gestational diabetes, which are two serious diseases that affect the mother's health and safety and the safety of the fetus if the pressure and sugar numbers are not monitored and controlled. Within acceptable limits.
Placental problems: During labor and childbirth, the placenta may separate from the uterus before birth, leading to a decrease in the amount of blood delivered to the fetus. This is a risk that may threaten the safety of the fetus and lead to its death in some cases, and the placenta may be located low and cover the cervix, which exposes it to bleeding easily, or the placenta implants Inside the uterine muscle and stick to it, which makes separating it after childbirth difficult and exposes the mother to the occurrence of profuse bleeding.
• In other cases, the uterus is not able to contract after childbirth, because it has expanded so much that it temporarily loses its flexibility and ability to contract, and this is called uterine inactivity. As a result, profuse bleeding occurs and threatens life.
• Embryos can also be born early, which will expose them to weight loss and various problems of prematurity, such as difficulty breathing and insufficient maturity of the organs for life outside the womb.
There is another very important problem, when the two fetuses share one placenta, they do not divide the amount of blood equally, but one of them takes a large amount of blood at the expense of the other, so the first fetus has a large amount of hemoglobin and this is called redness of the blood, while the second develops anemia, and will be exposed The two cause important problems and serious complications, so red blood is no less dangerous than anemia.
Most of the previous problems occur in a single fetus, but they occur more frequently when the mother is carrying twins, so pregnancy and childbirth should be monitored by a doctor with long experience in dealing with high-risk pregnancies.
What is the right time for the birth?
Although natural childbirth is possible, many doctors prefer cesarean delivery in the event of a twin pregnancy, especially if both heads are not facing downward, and the appropriate decision for childbirth is made based on the opinion of the specialist following the case.
