The odds of conceiving twins are pretty low; for every 89 childbirths one of them is a pair of twins. In the US, only three percent of pregnancies result in multiple births. Also, a majority of these twin childbirths correspond to fraternal twins, and in very rare cases is it that identical twins are born. Interestingly, women who are older have a higher likelihood of having twins, despite the fact that they have lower chances of achieving pregnancy. If you and your partner wish to conceive twins, there are numerous methods through which you can try increasing the odds.
