Many couples try to conceive with the hope of having twins. Their motivations vary, from ensuring that their child has siblings from an early age to simply wanting a larger family. In the United States, the twin birth rate stands at around 3% of all pregnancies each year, but experts suggest that women can take certain steps to increase their chances of carrying twins. Diet, ethnicity, genetics, and lifestyle all play a crucial role in determining whether a woman is likely to have twins. If you're interested in learning how to increase your chances of carrying twins, follow the steps outlined below.
Steps
Understand Your Current Chances

Know that the average chance of having twins for a typical person is around 3%. It's not particularly high. However, you may not fall into the average category. Your chances of carrying twins will increase if you possess any of the factors listed below. If you have several or all of these factors, your likelihood increases significantly. Conversely, if you're a young, lightweight woman from an Asian family without a history of twins, your chances are very low.
- Having twins in your family, particularly on the mother's side, increases your chances. If you have twins in your family, your odds are at least four times higher.
- Being of African descent boosts your chances the most, followed by those of European descent. Hispanic and Asian people have the lowest likelihood of carrying twins.
- Having an ideal height and/or good nutrition, or even being overweight, can improve your chances.
- Having had previous pregnancies. Women who have been pregnant four or more times significantly raise their chances of carrying twins. It seems the body becomes more capable of carrying twins once it knows you can handle it. Many families with ten or more children have shown that the number of twins increases with each successive pregnancy.

Understand that older women have a lower chance of becoming pregnant, but if they do, they are more likely to carry twins. The older you get, the higher your chances of having twins. If you're in your 40s, your chances of carrying twins are about 7%. If you can conceive at 45, the likelihood of twins increases to around 17%.
- Older women often need in vitro fertilization, which also increases the chances of having twins. See the section below. IVF can further boost your chances of carrying twins.
Simple Ways to Boost Your Chances
Take vitamin supplements.

Maintain a nutritious diet and consume specific foods. Generally, underweight individuals are less likely to carry twins.
- Overall, having a better diet or being overweight may increase your chances of carrying twins.
- A better diet means gaining weight in a healthy manner. Consult with your doctor if you plan to gain weight.

Consume dairy products and cassava. Certain foods may increase your chances of carrying twins.
- A study conducted by leading fertility experts reveals that women who consume dairy products while trying to conceive are five times more likely to have twins than those who avoid these foods.
- The Insulin-like Growth Factor (IGF) produced in cows' livers is believed to be the key chemical behind this phenomenon.
- It is suggested that drinking milk from cows treated with growth hormones (rBGH) may have a greater impact on a woman's chances of having twins.
- An African tribe with a diet rich in cassava (manioc) boasts a twin birth rate four times higher than the global average. The nutrients in this root are believed to stimulate the ovaries to produce more than one egg during ovulation.
- Many doctors are skeptical about cassava's role in twin births. However, eating cassava is harmless and quite tasty.

Stop using birth control pills. Cease using birth control pills just before attempting to conceive. When you stop taking birth control, your body will react strongly to readjust its hormones. In the first month or two after discontinuing birth control, sometimes the ovaries may release two eggs.
- This has not been definitively proven, but it appears to have no negative effects. Some studies support this possibility.
Conceiving Twins with Medical Assistance

Let your doctor assist you in increasing your chances of carrying twins. Some doctors will help anyone who wants to have twins, like the doctors involved with Octomom. However, other doctors will only assist if it is deemed a "medical necessity."
- There are various medical reasons a doctor may support the idea of carrying twins.
- If you are older, a doctor might encourage twins to avoid birth defects compared to having two separate pregnancies.
- There are other reasons why a healthy woman might struggle to conceive more than once, a condition known as Secondary Infertility. Age and the period during which you can conceive are additional factors that might lead to twins.

If you are undergoing in vitro fertilization, expect significant costs. Since each egg fertilized via IVF has a lower chance of implantation, transferring multiple embryos is often considered a better option. Therefore, it is recommended to try implanting multiple embryos simultaneously.

Consult your doctor about a medication called Clomid. Clomid is often prescribed to women who do not ovulate, but when used by healthy women, it can increase the chances of having twins by up to 33%, depending on the woman's body.
- Clomid works by stimulating the ovaries to release more eggs during a cycle. It may even lead to triplets or more, so caution is advised when taking this medication!

Consider using IVF (In Vitro Fertilization). IVF was once known as the "test tube baby" method.
- IVF increases the likelihood of carrying twins. Typically, doctors will try to implant multiple embryos with the hope that one will implant, but sometimes both can. Generally, the chances of having twins through IVF range from 20% to 40%.
- IVF can be costly. Many clinics offer IVF services, so it's important to do thorough research and find the right one for you.
- IVF has become quite common nowadays. While expensive and time-consuming, it has become a standard option in today's world.
Advice
- In the U.S., for every 89 natural births, there is one set of twins. Only 0.4% of all twins are identical.
- Carrying multiples increases the risks, including preterm birth, low birth weight, and the possibility of birth defects.
Warnings
- Consult with your doctor regarding your plans to try for twins. Everyone's situation is unique, and some of the information provided may not apply to your specific case.
- Never take any medication unless prescribed by your doctor.
- It's especially important to get your doctor's advice on weight gain or loss and your diet.
- IVF can be expensive, and it doesn't always guarantee success.
