Multiple pregnancy: when the stork brings more than one baby

Care during a multiple pregnancy

Multiple pregnancies are rare in the human species

Although they may occur naturally, the increased use of assisted reproduction techniques has resulted in abortions of this type in recent years.

We tell you what factors increase the possibility of having a multiple pregnancy.

Types of twins

  • Monozygotes (twins)

They occur when an embryo divides into two identical halves, and two embryos are formed with identical DNA, are of the same sex and have the same blood group.

The division occurs in the first days after fertilization, and depending on the moment in which this division occurs, babies can share the same placenta or not.

  • Dizygotic (twins)

They occur when two ovules are fertilized by two different sperm cells.

The similarity between two twin brothers is the same as between two brothers born at different times. They always have separate placentas.

What factors increase the possibility of having a multiple pregnancy?

The identical twins or monozygotic, which make up about a third of multiple pregnancies come from a single egg and are basically a fluke of nature.

But with non-identical twins or when there are more than two babies, which come from different ovules, if there are some factors that can influence, such as:

  • Family background

If the woman has a family history of multiple pregnancies, there will be more possibilities.

  • Lifestyle

  • Number of children

This is a matter of probability: the more children you have, the more likely it is that at some point a multiple pregnancy will occur.

  • Maternal age

It is more common that twin pregnancies occur naturally in women between 30-40 years.

This is due to the changes that occur in the functioning of the ovaries with age, which can release more than one egg each month.

  • Origin

In Western Europe, 1 in 60 pregnancies is twin, while they are much rarer in Southeast Asia.

  • Fertility treatment

Medications are used to stimulate ovulation and produce more oocytes.
