The largest multiple birth on record is nonuplets. This refers to a pregnancy in which nine babies are born at the same time. To date, there has only been one recorded case of nonuplets in history, which occurred in Sydney, Australia in 1971. However, the pregnancy was extremely rare and only five of the nonuplets were born alive and lived only a few hours. As a result, it is considered a very rare and unusual occurrence in human history.
What is the largest multiple birth?
The largest multiple birth on record is octuplets. This refers to a pregnancy in which eight babies are born at the same time. The first recorded case of octuplets occurred in Houston, Texas, USA, in 1998, when a woman named Nadya Suleman gave birth to eight healthy babies. Before that, the record was held by septuplets born in 1997 in the USA and in Malaysia in 1999. But all of them were born prematurely and did not survive.
It is important to note that multiple births of this magnitude are extremely rare and are often associated with fertility treatments. The survival rate of octuplets is also very low and many of the babies born may have long-term health complications.
What is the highest number of babies in one pregnancy?
The highest number of babies born in one pregnancy is nine. This is known as nonuplets. However, to date, there has only been one recorded case of nonuplets in history, which occurred in Sydney, Australia in 1971. However, the pregnancy was extremely rare and only five of the nonuplets were born alive and lived only a few hours. Due to the high risk involved with multiple pregnancies and the low survival rate of multiple births, it is very rare for any more than eight babies to be born at one time and survive.
What is the largest natural birth of multiples?
The largest known natural birth of multiples is septuplets. This refers to a pregnancy in which seven babies are born at the same time. The first recorded case of septuplets occurred in 1997, when a woman named Bobbi McCaughey gave birth to seven healthy babies in Iowa, USA. This pregnancy was considered a medical miracle at the time as all the babies were born healthy and all of them survived.
It is important to note that multiple births of this magnitude are extremely rare, even with fertility treatments and the survival rate of septuplets is also very low. Most of the septuplets born are premature and have long-term health complications.
What causes multiple births?
Multiple births occur when a woman becomes pregnant with more than one fetus at a time. There are several different factors that can cause multiple births:
- Fraternal twins: These occur when two eggs are released from the ovaries during ovulation, and both eggs are fertilized by sperm. This results in the formation of two separate embryos.
- Identical twins: These occur when one fertilized egg splits into two separate embryos. This results in the formation of identical twins who have the same genetic makeup.
- Fertility treatments: Assisted reproductive technologies (ART) such as in-vitro fertilization (IVF) and ovulation induction (OI) are known to increase the likelihood of multiple pregnancies.
- Genetic factors: Some families have a genetic predisposition to fraternal twins, which means that they are more likely to have twins due to certain genetic variations.
- Women who are over 35 years old are more likely to have multiple pregnancies, as their chance of releasing more than one egg during ovulation increases as they age.
It’s important to note that multiple pregnancies are associated with a higher risk of complications for both mother and babies, and the survival rate is lower than single pregnancies.
