If your dream is to have twins, the first thing you should know is that the probability of getting pregnant with twins depends on the mother's genetics or in vitro fertilization, in my case for example I inherited the hereditary factor from my maternal grandmother. Multiple pregnancy involves the development of two or more fetuses in the uterine cavity, unlike single pregnancy, where there is only one developing fetus.

The pregnancy of fraternal twins (identical twins) occurs when only a single egg is fertilized and then it splits into two, which is still a tremendous mystery to doctors, as well as being much rarer than the pregnancy of two. fraternal twins. Also called dizygotic twins, that is, pregnancy of non-identical twins in which 2 eggs are released and fertilized, with 95 % in cases of twin pregnancy.

But even if you or your husband doesn't have twins in the family, the chances are minimal, but it's possible to be the lucky one to be the first to debut this miracle, after all when God wants not even medicine explains.

What are the chances of getting pregnant with twins naturally?

If your dream is to carry two babies at the same time in your womb, it is necessary that you know some factors, the main one for a mother to have twins naturally is genetics. If there is at least one case of twins in the family on the mother's side, yes, the hereditary factor has to come from the woman, so there is a high probability of a twin pregnancy.

In some rarer cases, there are those who have a natural predisposition to have double ovulation, which facilitates the fertilization of two or more eggs at the same time. Below you will find out what are the many other factors that when combined can further increase your chances of conceiving with twins.

Mother's age


I don't know if I agree with this factor, since most of the mothers of twins I know are under 30 years old, I for example had my boys when I was 22 years old. But, according to research, women over the age of 35 have a higher chance of multiple conception. The hormonal factor causes an increase in follicular stimulation of the ovary causing the follicles to produce multiple eggs. This means that women who are mothers at older ages are more likely to have twins than younger mothers.

It is paradoxical because, although at this age there is less chance of pregnancy, hormonal imbalances that occur at the end of the childbearing years make it more feasible to ovulate twice in the same menstrual cycle. An estimated 70% of women over 45 have twins. It is paradoxical because, although at this age the chance of pregnancy decreases, because of the hormonal imbalances that occur at the end of the childbearing age, making double ovulation in the same menstrual cycle more feasible. An estimated 70% of women over 35 have twins.

family inheritance

Having a family history of multiple pregnancies increases the chances of having them. 17 % of twins have twins. That is, women who have twins in their family are more likely to get them than women who have no history of twins in their family. In the event that the father who has a family history of twins will most likely be transferred to his daughter (if any).

Black race

Evidence shows that there is a higher percentage of twins among black women, Asian women for example are less likely to have twins.

Weight – BMI greater than 30

Overweight women produce more estrogen, which can stimulate the ovaries to release more than one egg.
