Multiple births (delivering twins, triplets or more) is common with fertility treatments. But the couple conceived naturally. Spontaneous triplets are rare, occurring in 1 in almost 7,000 pregnancies. Other data puts the chances even lower, with naturally occurring triplets occurring in 1 in 10,000 pregnancies.
Naturally conceived triplets occur in about one and every 10,000 pregnancies.
Identical twins or triplets happen when a single egg is fertilized and then later splits. These newly divided embryos are identical. Children that are identical multiples will look like each other and be the same sex. Fraternal multiples develop from separate eggs that are fertilized by a different sperm.
The odds of conceiving “spontaneous” triplets – meaning without the aid of fertility treatments – are only about 1 in 8,100.
Twins are by far the most common form of multiple births in humans. The U.S. Centers for Disease Control and Prevention report more than 132,000 sets of twins out of 3.9 million births of all kinds each year, about 3.4%, or 1 in 30.
Hyperovulation-stimulating foods: There are a few foods that naturally increase the rate of ovulation and stimulate ovaries to release multiple eggs. Such hyperovulation stimulating foods include cassava (an African wild yam or sweet potato), tofu, soy isoflavones, whole grains, and whole wheat.
There's no scientific limit, but the largest reported number of fetuses in one womb was 15.
White people assigned female at birth have the highest rate of higher-order multiple births (triplets or more). This is especially true for those older than 35.
When more than one ovum is fertilized and implants in the uterus, the result is dizygotic (fraternal) twins, triplets, or other multiples. Although two fetuses develop simultaneously in superfetation, they differ in maturity, having been conceived days or even weeks apart.
“Most experts put the odds of identical triplets at one in 200 million births,” Tiberius said. “I talked to a statistician and apparently the odds of a 45 year old having identical triplets are one in 20 billion.” It's quite rare to become pregnant without medical intervention at 45, according to Dr.
Superfetation is rare because, once a person is pregnant, changes in their hormones typically prevent their body from continuing to ovulate, Dr. Greves explained. But if a person does ovulate again—and if that egg becomes fertilized and implants in the uterus—they can carry a double pregnancy.
Both parents have said that the nonuplets were conceived naturally. The four boys and five girls have been named: Mohammed, in honour of the king of Morocco, Bah, in honour of the former president of Mali, El Hadji, Oumar, Hawa, Adama, Fatouma Oumou and Kadidia.
The majority of triplets are what is known as trizygotic. This is because they are formed when three separate, individual eggs are fertilised by three separate sperm. These babies share the same characteristics as any other siblings with the same biological parents. They can be the same or opposite genders.

About 1 in 3 of all sets of twin births are vaginal births. You may choose to have an elective caesarean, or your doctor may recommend a caesarean section because of potential complications. Even if you plan a vaginal birth, you may end up having an emergency caesarean section due to complications during labour.
Meet the Record- Breaking Nonuplets.
It is possible to have triplets where two of the babies are identical twins (and may share one placenta, and even one sac) and the third baby is non-identical (with completely separate placenta and sac). This is very rare.
The average length of a pregnancy for triplets is 32 weeks. For quadruplets, the average length is 30 weeks. Continuing a multiple pregnancy past 36 weeks can be risky for you and your babies. So, it's usually considered best to deliver them early.
And the chances that they will be two of one sex and one of the other are 75 percent. (Two boys and one girl = 37.5 percent; two girls and one boy = 37.5 percent.)
Everyone has the same chance of having identical twins: about 1 in 250. Identical twins do not run in families. But there are some factors that make having non-identical twins more likely: non-identical twins are more common in some ethnic groups, with the highest rate among Nigerians and the lowest among Japanese.
If you're older than 30, there's a greater chance you'll have multiples. Previous pregnancies. If you've been pregnant at least once before, you're more likely to have a multiple pregnancy your second or third time.
Women can reproduce for about half of their lifetime and can only give birth about once every year or so. So it makes sense that women can only have a fraction as many children as men. One study estimated a woman can have around 15 pregnancies in a lifetime.
Your fertility after having a baby
Some women feel that they won't need contraception so soon after having a baby, especially if they have found it difficult to get pregnant before. But your body goes through lots of changes during pregnancy and for some women they can have increased fertility.
The couple conceived quadruplets naturally, an extremely rare occurrence that happens in just 1 in 700,000 pregnancies. Approximately 90 percent of quadruplets are conceived with the assistance of medical technology.
