The story of the most prolific mother ever

An 18th-century woman tricked doctors into believing she gave birth to rabbits.

Couple welcomes rare quadruplet daughters who are actually a set of twins

The four healthy girls were delivered by cesarean section and joined a larger family that includes their parents and a 2-year-old older brother. Without the use of fertility drugs, quadruplet births are rare, but the chances are even slimmer that they'll be sets of identical twins. Medical professionals say the odds are around one in a million.

Triplet birth numbers are dropping—and that may be a good thing

Pregnancies involving three kids or more have dropped 62% from 1998 to 2023, a trend that the Centers for Disease Control and Prevention links to fewer embryo transfers during assisted reproduction procedures—a transition prompted by more refined techniques and technical advances. Though multiple births can occur naturally, often pregnancies involving multiple births have been the result of efforts to ensure pregnancy success by transferring multiple embryos.

Why humans evolved single-child pregnancies

While birthing twins has been a rare occurrence for humans, research suggests that twins were actually the norm much further back in primate evolution. It’s proposed that single-childbearing turned out to be critical for the evolution of larger babies with larger heads. Discover more about the shift that gives insight into primate evolution.

Eight British children have been born via mitochondrial replacement therapy

In July 2025, a decade after British lawmakers signed off on allowing three-parent IVF, scientists announced that eight healthy babies had already been born using this approach. The news was included in a pair of research articles published in a peer-reviewed journal that noted the oldest kids were already more than two years old, and that they were hitting developmental milestones as expected.

The first successful IVF pregnancy was in the United Kingdom in 1978

Gynecologist Patrick Steptoe and his collaborator Robert Edwards, a biologist, attempted to fertilize a human egg cell in a petri dish 101 times before finally succeeding. This resulted in the birth of Louise Brown—at the time referred to as a "test tube" baby—in 1978, who was born into the spotlight.

Extremely rarely, there can be twins with different dads—but fewer than 20 such cases are documented worldwide

The non-identical twins, who would also be half-siblings, result from a rare biological phenomenon called heteropaternal superfecundation. Britain's first known twins with different dads, featured in this article, learned of each other's existence in recent years, when they were both 45. They discovered each other after taking DNA tests from Ancestry, a genealogy company.

France once had a reproduction czar to help midwives deliver babies

Much ado is made about falling marriage and birth rates worldwide, and how they might affect tax bases, retirement funds, and social standing. But this isn’t the first time marriage, and subsequently reproduction, have fallen out of favor. Some countries have resorted to drastic measures to restore the tarnished state of these hallowed institutions.

In the US, 3.6 million babies were born in 2023

That year, about 40% of the babies were born to unmarried parents, and about 32% of the births were born via cesarean. On average, mothers were 27.5 years old when they had their first child.

The US president who had the most children

John Tyler, America’s 10th president, was born in 1790, yet still has one living grandchild. This bizarre phenomenon can be explained by his 15 children, which he had throughout all stages of his adult life. Tyler had eight children with one wife and seven with another, leading him to hold the title as the US president with the most children. Tyler was also the first US president to get married while in office.

Four frozen embryos in the US were created via 3-parent IVF technique

Columbia University researchers created four embryos using mitochondrial replacement therapy for four female patients who didn't want to pass on mitochondrial diseases to their children.

While he has six children with his ex-wife Justine Musk, he has three with the musician Grimes, including a son named X Æ A-12.

Women are born with all the eggs they will ever produce in their lifetimes

Girls are born with an estimated 1 million to 2 million eggs in their bodies, but around 10,000 die monthly before girls hit puberty. Scientists have not yet figured out why there's such an excessive number of eggs prior to menstruation, but they've calculated that there are roughly 300,000 to 400,000 eggs left at puberty.

The Hungarian countess rumored to have bathed in blood

According to legend, Hungarian countess Elizabeth Báthory killed up to 600 women to bathe in their blood and preserve her youth. Such allegations have been challenged since the 1980s when Slovakian archivist Josef Kocis published a book detailing new aspects of Báthory's life and included possible evidence of a conspiracy meant to undermine her power as part of Transylvania's ruling dynasty.

Why South Korean women are having fewer babies

For decades, Asian countries have been combating dwindling birth rates by basically bribing families into having more children: offering government-subsidized housing, free IVF treatments, and even straight-up cash handouts. It hasn’t worked. In this BBC video, a TV producer, a cartoonist, and a private-school teacher explain their views on having children in 21st-century Korea.

3-parent IVF removes most—but not all—faulty mitochondria

The process scoops out about 99% of the mother's mitochondrial DNA—replacing it with that of a donor woman—but because that roughly 1% is still in the system there is still a small chance of disease for the resulting child or future generations. (Some users may encounter a paywall.)

Without 3-parent IVF, women carrying faulty mitochondrial DNA have few options for children

Women who are carriers of mitochondrial diseases that wish to have children without those conditions cannot be biological parents without three-parent IVF. The alternatives are to adopt or have a child via egg donation.

As of 2022, scientists estimate that 117 billion people have been born on Earth

Although no demographic data exist for more than 99% of the time humans have existed, this value can be estimated by tracking approximate population sizes over different periods and the birth rates within those periods. In 2022, about 6.8% of humans that have ever been born were alive.

Modern Champagne owes much of its existence to one woman: Widow Clicquot

Barbe-Nicole Ponsardin, better known as the Widow Clicquot, might not have actually invented Champagne, but her innovative approach to winemaking yielded many techniques still used today. Taking over her husband’s failing business after his death, the Widow Clicquot combined business savvy and innovative thinking to make the process easier, more efficient, and, most important, more profitable.

The US trails behind other developed countries in reducing its stillbirth rates and may learn from Australia

Australia is in the vanguard of efforts to bring down stillbirth numbers with a national stillbirth plan integrated into its healthcare system, supported by clinicians, nurses, midwives, and politicians. Its work also includes a public awareness campaign, more regular fetal monitoring and follow-up for potential interventions, and more maternal advice about care and safety during pregnancy.

South Korea has the lowest fertility rate in the world

If current birthing trends persist, every hundred South Koreans today will have only six great-grandchildren between them. This crisis is a result of high expenses, harsh work-family trade-offs for women, declining marriage rates, and other societal factors. Some newer policies are helping to build incentives for having children, but larger issues also need to be addressed.
