chances of having twins

Just what are your chances of having twins? Without doing anything at all to try to help it along, the odds are usually around 3%, or 3 times in 100 births.

There are some things you can do to try to increase your chances, but there’s really no guarantee unfortunately.

Some researchers believe that the following may have something to do with your chances of having twins so if you can have any control over these it may be worth a try!

  • eat dairy products regularly, such as milk, yogurt, cheese
  • eat lots of yams
  • wait to get pregnant until you’re older than 35
  • have a BMI (body mass index)of at least 30
  • if you’ve had children already, especially if you’ve had fraternal twins already
  • getting pregnant immediately after going off birth control pills
  • getting pregnant while breastfeeding
  • using fertility methods such as drugs or in vitro fertilization

Chances of Having Twins Naturally

Research has shown that eating plenty of dairy products increases your chances of having twins by 5 times the normal average compared to women who do not eat dairy, such as women who follow a vegan diet.

Women who live in certain parts of the world where yams are a regular staple in their diet have the most twins of all. It’s said that there is a natural hormone in the yams, phytoestrogen, that stimulates ovulation, sometimes causing hyper ovulation resulting in more than one egg being released at a time.

A town in Nigeria, Igbo-Ora, has the claim to fame of having the most twin births in the world at 4 times the average. Their staple crop is yams, which is eaten daily.

In the United States the highest number of twin births are in the northeastern states of Connecticut, New Jersey, and Massachusetts.  The states with the least amount of twins born are New Mexico, Alaska, and Arizona.  The country with the least twins is China.

These statistics come from data that is recorded from hospitals and other institutions that keep track of births. It’s not really known why the chances of having twins are greater in some places and not others, but one idea is that because twins are more likely to occur in obese women and with the rate of obesity rising, so are twin births.  Evidently there is less obesity in the western states of the US than in the east.

Chances of Having Twins With IVF

Women who use IVF (in vitro fertilization) have 20 – 40 % more chances of having twins or possibly even more, depending on how many embryos they have placed in their womb. A major risk though is not knowing how many of the placed embryos will be successful.

Placing more embryos gives more of an opportunity for at least one success, but what if 4 were placed with the hope of having twins and all 4 were successful. Wow! Instant large family! To be considered also is the greater risk of complications to the mother and the babies in a multiple pregnancy of that proportion.

According to the CDC, the percentage of IVF pregnancies with twins is approximately:

  • 33% for women under age 35
  • 27% for women age 35-37
  • 22% for women age 38-40
  • 13% for women age 41-42

Chances of Having Twins On Clomid

How does Clomid work? Clomid tricks the brain into thinking it needs more estrogen, which then hopefully will cause your body to produce more in the form of follicles in your ovaries. Along with producing more GnRH, which causes the release of FSH and LH, the follicles ripen with the help of the FSH and ovulation occurs.

For a woman with ovulation problems, Clomid can regulate her cycle and help with the releasing of an egg in order to attain pregnancy. Many women without ovulation issues take this drug to encourage multiple egg release in the hopes of increasing their chances of having twins on Clomid. On average, women who take this drug increase their chances of having twins by 7-8%.
