Superfetacion: the phenomenon that allows you to get pregnant while pregnant

As you have read it: it is perfectly possible-although really very unlikely-to get pregnant when you are already pregnant.All this happens thanks to a phenomenon called "Superfetacion", which occurs when twins are conceived several days or weeks apart, the result of two separate ovulations and can be from two different parents or the same father, happening the fertilization of the second after the first has already been implanted.

The superfetacion process is commonly found in several animal species such as sheep, horses or rodents. However , in humans it happens only in exceptional cases.

Superfetacion: the phenomenon that allows you to get pregnant while pregnant

And now comes the Question around your mind: Why and how can this happen? This is an error in the process called reproductive block, which usually occurs after conception .Explained in a simple way, at the time the woman becomes pregnant, The body sends a signal that blocks the ovaries so that no more oocytes mature during pregnancy, which is why there is an absence (in the vast majority of cases) of menstruation during the time of pregnancy.

When this "error" happens and the blockage does not happen, it is possible that a new egg is released and that it is fertilized .Then comes the most complicated thing, so that it is superfetacion, the embryo must achieve stay in the uterus (although there is another embryo).

According to several studies, superfetacion may be related to fertility treatments or assisted reproduction, since in most cases that have been Presented worldwide, there have been such prior procedures.

A Well, how is pregnancy and childbirth? On this, it is fair to point out that both pregnancy and childbirth are usually handled in the same way as when it comes to traditional twins .As for childbirth, it is common to be by caesarean section and well planned by the gynecologist, mainly based on the age and level of maturation of the less developed twin, so that he is not born premature.

And you? Procrastines too? If you don't, we are sure that you know someone who does it continuously and that, surely, makes you despair.But what does this disturbing word really mean? Let's give an example: you have been dating a person for a long time, you make plans for the future, you have many illusions and projects, however, your partner never seems to decide.He is unable to formalize your relationship because something like that, not only overwhelms him, but even He is lazy.

According to anthropologist Helen Fisher love comes to last for some 4 years .Just that first period of infatuation in which the sexual attraction is very important and in which at the end, touching the 4 years, there is offspring., then, in the second phase which is the carino , in which together we raise and educate, and in which that initial sensation fades away.Finally, comes the desire for separation.And, According to this anthropologist, this process is natural, since our organism cannot bear for a long time the ferris wheel of sensations that we feel, due to the chemistry that is generated when we fall in love : the high levels of dopamine, testosterone and norepinephrine that our brain secretes.That is why they have an expiration date: between 1 and 4 years! Researchers at the University of Pisa al...

This is a cycle that starts at the moment that industries, factory smoke or car engines emit sulfur oxides in the gaseous state that is transported through the winds to hundreds of kilometers.By burning different kinds of fuels considerable amounts of chemicals are released, which not only contain visible particles of gray color, but also have a wide variety of gases not visible, but very harmful for the environment . Acidity values In the troposphere , one of the layers that make up the at...

The camel arana is not a proper spider, is part of the arachnid group, but it is actually a solpugido .It is believed that there are about 1,100 species of camel spiders, most of which have not yet been studied, since this is a somewhat complicated task: because they seem to wilt when taken to laboratories and must be observed directly in their natural habitat.
