People change their way of life, go through all sorts of examinations, in order to give birth to the coveted baby. But is it possible to plan the birth of not one but two or three kids at once - what is the probability of giving birth to twins?
Who are the twins?
And similar and unlike kids officially are called twins, only the first ones are monozygotic, and the second ones are dizygotic. So, a couple of babies who have the same set of chromosomes, identical external data, originated from one bisected egg (one sperm will fertilize it).
These children are in most cases male, and at birth one of the pair is markedly different in height and weight from the other. Possible pathologies in the development of a less powerful baby.
What is the chance to give birth to monozygotic twins?
Of all the multiple pregnancies, absolutely identical twins are born only in two percent of cases. In order to find out what the probability of the birth of such twins is in your family, you need to carefully check the pedigree and make sure that in the near future there was already such a precedent, and perhaps not one.
These data are important only if there were twins along the female line, according to which this probability to give birth to twins and is transmitted. If they are in the family of the husband, this, unfortunately, does not give a chance to have the same kids to your family.
What is the probability of giving birth to twins from an ordinary couple?
If you do not have twins or twins in your family, the chance to give birth to them is negligible. There is an accident. But this can be helped, although there is still no guarantee of a multiple pregnancy.
Most often twins (children from different spermatozoa and eggs, not similar to each other) are born from mothers who have passed the age line of 35-40 years. At this time, the concentration of hormones that cause ovulation is very high and it is possible to yield two or more eggs instead of one.
These same hormonal leaps are observed not only in middle age, but also after winter, when nature awakens and light day increases. Ovulation in May - June is often double, but in the winter months, vice versa may be absent several months, because the hormonal background is very influenced by the duration of the day, the lack of avitaminosis and the autumn-winter depressive state.
And what is the probability of the birth of twins with IVF ? In this case, almost 90% of pregnancies are prolific. After all, to ensure the survival of at least one of the transplanted embryos they are planted at least two and often are born both.
The total treatment of female diseases with hormonal drugs has an effect that stimulates ovulation. If for half a year or more a woman takes such drugs for treatment or contraception, then on the abolition of the drug, in the first cycle, the probability of getting pregnant with twins is high.
That's why gynecologists advise women to take additional measures of protection in the first cycles after the end of hormone intake.
How often are twins born?
If there are several pairs of twins in the family along the female line, then most likely they are born in a certain sequence. That is the probability of the birth of twins arises after one or two generations. For example, if the grandmother had a multiple pregnancy, then the same inclination will be with her granddaughter, but not with her daughter. This is the so-called recessive trait.
Whether it is necessary to trust in nature or try your best to circle it, it's up to you, but we should not forget that a double pregnancy is an increased burden on the female body and a risk of fetal anomalies.
