Historic period

People over 30 are more likely to conceive twins. This is because follicle-stimulating hormone (FSH) rises as birthing parents get older. FSH is responsible for the evolution of eggs in the ovaries before they are released.

Family History

A family history of identical twins does non necessarily brand y'all more likely to have multiples, although the offspring of male identical twins may be more likely to have their own identical twins. Withal, if you lot have fraternal twins (not-identical) in your family, your chances of conceiving twins rise. If there are congenial twins on both parents' or egg or sperm donor's sides, your odds for twins get up fifty-fifty higher.

A history of congenial twins on the maternal side of the family indicates a college likelihood of ovulating more than one egg per wheel.

Weight

People with a BMI over 30 are more likely to conceive twins than people with a lower BMI. Extra body fat leads to increased levels of estrogen, and higher levels of estrogen tin pb to overstimulation of the ovaries. Instead of releasing merely i egg at ovulation, the ovaries may release ii or more. While the odds of twins may increase, other factors associated with beingness overweight can make information technology more than hard to conceive.

Height

People who are taller than average are more likely to take twins. Ane report establish that people averaging 164.8 cm in height (about v'4.eight") were more than probable to conceive twins than people averaging 161.eight cm (well-nigh 5'iii.seven"). Why this happens isn't clear, just one theory is that meliorate diet (which may lead to more height) is partially behind the increased rate of twins.

Breastfeeding

People who conceive while breastfeeding are more likely to conceive twins than people who are not. Information technology'south truthful that breastfeeding can also suppress fertility and prevent pregnancy, specifically during a baby'southward get-go half-dozen months if the baby is exclusively breastfed. However, it is possible to get meaning when breastfeeding—and with twins!

Ane study found the rate of twins to be xi.four% amidst breastfeeding people equally compared to but 1.ane% amid non-breastfeeding people.

Diet

While inquiry is still ongoing, some studies accept found that people who eat a lot of dairy products are more probable to conceive twins. Ane theory is that the growth hormones given to cows affect the hormone levels in humans.

Other Factors

Twins are more than common in people who have carried many pregnancies and have large families. Meanwhile, Black people besides are more likely to excogitate twins than White people, while Asian people are the to the lowest degree likely to conceive twins.

Odds of Having Twins With Treatments

Fertility treatments that boost ovulation can pb to twins, triplets, or higher-lodge multiples. Conceiving multiples is a potential run a risk of fertility treatments and one that can possibly be reduced with conscientious monitoring and targeted handling such as single embryo transfer with IVF treatment or using the everyman possible effective dosage when treating with gonadotropins.

You may wonder why conceiving multiples is considered a "risk" and not a potential benefit to fertility treatments. Afterwards all, if you've been struggling to get pregnant, wouldn't a double or triple blessing be a good thing? The fact is that multiple pregnancies come with added risks to the parent and babies.

Not all treatments for infertility increase your odds of conceiving twins, simply well-nigh practise. Here are some of the treatments that may lead to twins.

Clomid (clomiphene)
Femera (letrozole)
Gonadotropins (as well known as injectables) like Gonal-F and Follistim
IUI treatment, when used along with fertility drugs
IVF treatment

	Overall	Clomid and Femera	Gonadotropins	IVF (nether 35)	IVF (ages 35–37)	IVF (ages 38–twoscore)
Twins	iii.21%	5–12%	Upwardly to 30%	12.1%	9.1%	5.3%
Triplets and Higher-Order Multiples	0.one%	<1%	Up to 5%

Clomid and Femera have the everyman rate of twins, ranging from 5% to 12%. The rate of triplets and higher-order multiples with these medications is under one%. Gonadotropins, whether used with or without IUI handling, take the highest charge per unit of twins and higher-order multiples.

Co-ordinate to some studies, upward to 30% of pregnancies conceived with gonadotropins pb to multiples. Most of these pregnancies are twin pregnancies, but up to five% are triplet or higher-order pregnancies.

Contrary to popular belief, IVF handling is not the main source of triplet and higher-guild pregnancies. Data collected by the CDC indicates that the rate of IVF-conceived triplets in 2014 was 1.5% of pregnancies (just but 0.9% of live births due to pregnancy loss).

IVF twins are relatively common, with the twin rate highest for people younger than 35 at 12.ane% per transfer in 2014. The IVF twin rate is lower for people over age 35 at 9.1% for people aged 35 to 37 and 5.3% for people ages 38 to xl, likely due to the overall decreased success rate as the gestational parent ages.

How Common Are Twins?

According to CDC birth statistics, at that place were 120,291 infants born in twin deliveries in the United States in 2019. That's 32.1 twins per one,000 alive births, or put another way, about 3.21% of live births. There were 3,136 triplet births and just 150 quadruplet and higher-society births during the aforementioned year. These numbers include naturally occurring multiples, along with those conceived with fertility treatment.

The rate of multiple births increased and peaked during the 1990s but has been declining over the past decade. The percentage of triplet and college order pregnancies has dropped 36% since 2004.

Chances of Having Identical Twins

In the full general population, identical twin pregnancies occur 0.45% of the fourth dimension, or 1 in 250 births. While most multiple pregnancies conceived with fertility treatments are fraternal twins, the utilize of fertility treatment also increases your risk of having identical twins.

According to one report, identical twins fabricated upward 0.95% of the pregnancies conceived with treatment. That's double the general population'southward risk. It's unclear why fertility treatment leads to more identical twins.

I theory is that the culture embryos are placed in during IVF increases the risk of identical twinning. Another theory is that treatments using gonadotropins lead to the increased risk of identical twins.

Odds of Higher-Order Multiples

Anyone trying to conceive will find their chances of having higher-order multiples much lower than twins or singleton births. Without fertility treatments, the odds of conceiving triplets spontaneously is around i in 1,800. For quadruplets, the odds are estimated to exist around ane in 729,000.

With fertility treatments, the chances of a college-order pregnancy ascension substantially. In 2019, for example, the rate for triplet and higher-lodge multiples was 87.vii per 100,000 births (0.877 per i,000 births). Estimates are that just over three-quarters of triplets and higher-order multiples are the result of fertility treatments.
