How to have twins

Learning how to have twins may seem like a fun way to expand your family as quickly as possible. But bear in mind there is not one factor that has been proven to guarantee a twin pregnancy. However, there are certain criteria that can increase your chances of having twins:

  • Heredity: Your odds of having twins increase significantly if your mother or maternal grandmother was a fraternal twin or gave birth to fraternal twins. This is an indication that you may have inherited a gene for hyper ovulation. Hyper ovulation is the tendency to release multiple eggs during ovulation, which is needed to conceive fraternal twins.

    Although men can carry the gene for hyper ovulation and pass it on to their daughters, a history of twins on the man's side of the family doesn't make a woman any more likely to give birth to twins when she becomes pregnant.
  • Age: Older women are significantly more likely than their younger counterparts to conceive twins. This is because older women are more likely to use fertility treatments in order to become pregnant. However, even when accounting for these factors, women over the age of 35 have natural differences in ovulation-stimulating hormones that increase their chances for conceiving twins.

  • Previous pregnancy: While this is another factor that overlaps with age, it appears that women who have already given birth are more likely to have twins than women who are experiencing their first pregnancy.

  • Obesity: Some researchers believe the recent increase in twins is associated with an overall rise in obesity rates.

    Studies have suggested that a woman's chances of conceiving twins increase if she has a BMI of 30 or higher. Still haven’t calculated your BMI? Go to “My Nutrition” part and find out what your BMI is.

    Since excess weight can lead to many other health problems, gaining weight is not a tactic that is recommended if you want to learn how to have twins. However, regardless of your weight, you should keep in mind that women who are well-nourished are more likely to have a healthy pregnancy. Go to "My Nutrition" part to get all the detailed information about how and what you should eat during pregnancy.

  • Diet: Consuming a diet that is high in dairy products may also increase a woman's chances of conceiving twins.
