What boosts the chances of having twins?
The thought of having twins is a dream to some – to others too much of a good thing. If you belong to the first category and love the idea of having a set of toddlers, you should read along as we have gathered a list of things which might influence the chances of having twin babies.
The older you are…
Age has an influence on your chances of becoming pregnant with fraternal (non-identical) twins. The older you are, the higher are the odds of having twins. Studies show that it is more common for women over 35 years of age than for younger women to have twins. This is due to an increased production of the hormone FSH which may lead to the release of multiple eggs compared to younger women.
A high BMI can increase the chances of having twins
Having a higher BMI (over 30) has also been linked to increasing the chances of having a twin pregnancy, according to previous studies. However, having a BMI over 30 is not recommended due to the fact that this places the woman in the category of obesity, which is not healthy.
It runs in the family
Twin pregnancy can also be dependent on your family history. The ability to conceive more than one egg is hereditary, and if your mother is a twin or you are even a twin yourself, your chances of releasing more than one egg to be fertilized will be higher. However, this does not apply for having identical twins which is not affected by hereditary conditions.
Fertility treatment can boost the chances of having fraternal twins. If you take fertility drugs which stimulate the ovaries, the chances of releasing more than one egg each month are higher. In some cases, in vitro fertilization (IVF) can also lead to having twins, if more than one embryo is inserted into the uterus. Though, today it is most common for fertility clinics to insert only one embryo in an IVF treatment.
Some races have higher chances of having twins
Statistics shows that African-American women are most likely to have twins. Asian and Latin American women are the least likely to fall pregnant with two babies at a time.
What about identical twins?
A pregnancy with fraternal twins is a result of the woman releasing two eggs that are fertilized at the same time. Falling pregnant with identical twins on the other hand is due to one fertilized egg splitting in two at a very early stage. This means that the two babies will have the same set of DNA and they will therefore be genetically identical.
While becoming pregnant with fraternal twins can be dependent on a range of different factors such as hereditary conditions, having identical twins is coincidental and can happen to any woman. An identical twin pregnancy is much more rare than fraternal twins. So, if your biggest wish is to double the joy, you must rely on the good luck.
