How to get pregnant with twins

Without in vitro fertilization (IVF), your chances of conceiving twins naturally are approximately 3%. However, these odds can increase based on factors like family history, maternal age over 35, African descent, and height. IVF significantly increases the likelihood of multiple pregnancies, though the American Society for Reproductive Medicine (ASRM) recommends single embryo transfer when possible to reduce risks associated with multiple pregnancies.

Several studies have found that women with higher folic acid (vitamin B9) levels have an increased chance of conceiving twins, possibly due to effects on ovulation. Taking a folic acid supplement is recommended anyway when trying to conceive, as it helps prevent neural tube defects like spina bifida. The FDA recommends 400-800 micrograms of folic acid daily for women of childbearing age who are planning pregnancy.

Sweet potatoes, yams, and cassava are believed to increase the likelihood of conceiving multiples by potentially promoting hyper-ovulation, where two eggs are released during a single cycle. While these foods are nutritious and part of a healthy preconception diet, scientific evidence is limited. Incorporating them as part of a balanced diet rich in nutrients supports overall fertility health.

Women who consume dairy products are said to be more likely to conceive twins, though the exact mechanism is unclear—it may be related to nutrients in dairy or growth hormones used in conventional milk production. If you're considering increasing dairy intake, it's worth discussing with your healthcare provider to ensure it fits your overall health plan and any dietary restrictions you may have.

At least one study suggests women who conceive while breastfeeding are more likely to have twins. However, breastfeeding can suppress ovulation in some women, making conception more difficult; if this occurs, you may need to stop breastfeeding to resume regular menstrual cycles. Discuss your breastfeeding and family planning goals with your OB-GYN to develop the best approach for your situation.

It's recommended to start taking prenatal vitamins, including folic acid supplements, at least one month before you begin trying to conceive to optimize your health. This preparation period allows your body to build up nutrient stores that support conception and early pregnancy development. Consult with your healthcare provider about the right supplement regimen for your individual fertility goals and health status.

If you've been trying to conceive naturally for over a year (or six months if you're over 35) without success, the American College of Obstetricians and Gynecologists (ACOG) recommends consulting a fertility specialist. IVF is the most reliable method to increase your chances of having twins, though it carries different risks and considerations. A board-certified reproductive endocrinologist can discuss your options and help you make an informed decision about fertility treatment.
