According to some research results show that in 100 births, about 2 births are twins with different eggs. Stay tuned for the following article to learn more about maternity twins and interesting facts.
Unlike identical twins , distinct egg twins appear when two separate eggs are fertilized by two different sperm cells, located in separate amniotic fluid in the mother's uterus and have a separate placenta. In this case, twins can be two females, two males or one male and one female (ratio of the same sex and the opposite sex is 50:50).
Genetically, these two babies have similar genetic makeup and are similar to those of other siblings in the family, which means that only 50% of the DNA structure is the same.
The gestation period of a normal pregnancy lasts about 40 - 42 weeks, but with different twins eggs or the same egg will be 37 - 38 weeks shorter and the average weight of these babies will be about 1.9 kg.
Since different-egg twins develop in an independent direction, these twins can differ from facial features, body shape to personality and preferences. As an adult, different babies with different eggs will also have different developmental tendencies.
The most common case of non-egg twins is when a mother's body has 2 eggs that release at the same time during a menstrual cycle and are conceived with two separate sperm. Together, the two fetuses develop in the mother's womb.
However, there are also cases of twins other than a special egg with a relatively low incidence, they are:
Multiple fertilization : It is also a twins, but the difference here is that the two eggs will meet with two sperm at different times. That is, an egg meets a sperm forming the first zygote, when this zygote develops for a few weeks, the second zygote is formed. So, after giving birth, one baby will be sturdy and bigger than the other.
Differential twins - different fathers : A mother can conceive a different twin with two different men, this is called a different egg twin - different from a father. Accordingly, when a woman is pregnant but ovulates again, this egg fertilizes the sperm of another person and develops in parallel with the previously formed fetus.
If identical twins are lucky, different twins can be affected by many different factors:
If you have a twin brother / sister in your family (with a different egg), it is likely that you will also have a different twin. However, if your husband has a twin, this will not affect your chances of having another twin, since you are the one who 'produced' the egg.
A recent study found that women with a body index (BMI) greater than 30 are more likely to get pregnant with twins, especially twins with different eggs.
Although pregnant older women will have many potential risks, these people are more likely to have twins, especially twins with different eggs. The reason is that during perimenopause, a woman's ovaries release more eggs each period and the body releases more of the hormone estrogen, which increases the ability to fertilize abnormally.
If you have been pregnant many times in the past, you will also be more likely to have twins. The more you are pregnant, the more likely you are to have a different twin.
If applying technology to support reproduction, especially in vitro fertilization will help stimulate more ovulation in each month, thereby increasing the chances of conceiving twins, especially twins with different eggs.
In the early stages of pregnancy, a mother can completely determine whether she is pregnant with a single pregnancy or twins through an ultrasound examination, but at this time it is not possible to distinguish between identical twins or different eggs. A mother can only know if she is pregnant with twins or different eggs after 12 weeks of pregnancy.
There are a number of cases, although doctors have determined that they are twins but when there is only one baby, this is called the twins disappear. Currently, science has not yet explained the cause of this disappearance.
Just like having twins with an egg, a person with a different pair of twins can have the following risks:
Caesarean
Preterm birth and low birth weight because a mother's uterus contains two fetuses
Causes high blood pressure
Increased chances of gestational diabetes
There may be each other striker
Recovery time is longer after birth.
The current pregnancy and twins are not uncommon, however, it depends on many different factors. Therefore, if you want to have a baby, right now, you should plan carefully and in detail or you can visit a specialist doctor to get useful advice for both.
