When Did IVF Begin? A Deep Dive into the History of In Vitro Fertilization
In vitro fertilization, or IVF, is a household name today, offering hope to millions of people dreaming of starting a family. But have you ever wondered when this groundbreaking technology first came to life? The story of IVF is a fascinating journey of science, perseverance, and human spirit. It’s not just about a single moment—it’s about decades of curiosity, trial, and triumph that changed the world of medicine forever. Let’s travel back in time to uncover when IVF began, how it evolved, and what it means for us today.
The Birth of IVF: A Milestone in 1978
The official start of IVF as we know it happened on July 25, 1978, when Louise Joy Brown was born in Oldham, England. She wasn’t just any baby—she was the world’s first “test-tube baby,” conceived through IVF. Her birth wasn’t a fluke; it was the result of years of hard work by two brilliant minds: Dr. Patrick Steptoe, a gynecologist, and Dr. Robert Edwards, a physiologist. Together, they cracked the code to fertilize a human egg outside the body and successfully implant it into a mother’s womb.
Louise’s arrival made headlines worldwide. For some, it was a miracle; for others, it raised big questions about science meddling with nature. But one thing was clear: this moment marked the beginning of a new era in reproductive medicine. Dr. Edwards later won the Nobel Prize in 2010 for his work, though Steptoe had passed away by then and couldn’t share the honor. Their achievement wasn’t just a one-off—it laid the foundation for millions of babies born through IVF since.
Before 1978: The Roots of IVF Go Deeper
While 1978 is the big date everyone remembers, the story of IVF started long before Louise Brown. Scientists had been tinkering with the idea of fertilizing eggs outside the body for over a century. Let’s rewind the clock to see how it all began.
Early Experiments in the 19th Century
Way back in 1878, an Austrian scientist named Samuel Leopold Schenk was already playing with the idea of IVF—sort of. He worked with rabbit and guinea pig eggs, mixing them with sperm in a lab dish. Schenk noticed that the eggs started dividing, a sign that fertilization might have happened. His tools were basic, and his results weren’t perfect, but he planted a seed for future researchers. Think of it like the first sketch of a masterpiece—rough, but full of potential.
Fast forward to the 1930s, and another scientist, Gregory Pincus, stepped into the spotlight. You might know him as one of the brains behind the birth control pill, but he also dabbled in IVF. Pincus managed to fertilize rabbit eggs in a dish and even claimed they developed into embryos. His work stirred up excitement—and controversy—because it hinted that human IVF might be possible someday.
The 1950s: A Breakthrough with Sperm
By the 1950s, the science was heating up. Two researchers, Min Chueh Chang in the U.S. and Colin Russell Austin in Australia, made a game-changing discovery: sperm needs to “mature” before it can fertilize an egg. This process, called capacitation, happens naturally in the female reproductive tract, but Chang figured out how to mimic it in the lab. In 1959, he used this trick to fertilize rabbit eggs and produce live baby rabbits through IVF. It was a huge leap forward—proof that IVF could work in mammals.
Chang’s success wasn’t just a cool lab trick. It showed that with the right conditions, life could begin outside the body. His work became a stepping stone for the human IVF experiments that would come later.
The 1960s: Closing in on Humans
By the 1960s, the focus shifted to humans. Dr. Robert Edwards was obsessed with figuring out how human eggs work. He teamed up with Patrick Steptoe, who had mastered a technique called laparoscopy—a way to peek inside the body and retrieve eggs using a tiny camera and tools. Together, they started experimenting with human eggs in the lab. In 1968, Edwards fertilized a human egg in a dish for the first time, watching it divide into a tiny cluster of cells. It was a massive breakthrough, but they still had to get that embryo to grow into a baby inside a womb.
Their early attempts hit roadblocks. Sometimes the eggs didn’t fertilize right; other times, the embryos didn’t implant. But Edwards and Steptoe didn’t give up. They tweaked hormones, adjusted timing, and kept pushing forward. Their persistence paid off a decade later with Louise Brown’s birth.
IVF’s Unsung Heroes: The Patients Who Took a Chance
Behind every scientific breakthrough are real people who take risks. For IVF, that meant couples like Lesley and John Brown, Louise’s parents. They’d been trying to have a baby for nine years with no luck because of Lesley’s blocked fallopian tubes. In 1976, they signed up for Edwards and Steptoe’s experimental treatment. It wasn’t a sure thing—dozens of other attempts had failed—but they were willing to try.
Lesley went through hormone treatments to boost her egg production, followed by a laparoscopic egg retrieval. Edwards fertilized the egg with John’s sperm in a lab dish, and a few days later, Steptoe implanted the embryo into Lesley’s uterus. Nine months later, Louise was born via C-section. The Browns’ courage turned a lab experiment into a living, breathing success story.
How IVF Took Off After 1978
Louise Brown’s birth wasn’t the end of the story—it was the beginning of IVF’s global rise. Clinics popped up worldwide, and scientists raced to make the process better, safer, and more accessible. Here’s how IVF grew in those early years.
The 1980s: A Decade of Firsts
The 1980s were a whirlwind for IVF. In 1981, the first IVF baby in the U.S., Elizabeth Carr, was born in Virginia. Just a year later, Australia celebrated its first IVF birth. The technology was spreading fast, and each success fueled more hope.
But it wasn’t all smooth sailing. Early IVF had low success rates—sometimes as low as 5-10%. Doctors started using drugs like gonadotropins to stimulate the ovaries, producing more eggs per cycle. This boosted the odds but also led to more multiple births (twins, triplets, or more), which brought new risks for moms and babies. Still, the demand kept growing as word spread about this “miracle” treatment.
The 1990s: Refining the Process
By the 1990s, IVF was getting a major upgrade. A technique called intracytoplasmic sperm injection (ICSI) debuted in 1992, where a single sperm is injected directly into an egg. This was a game-changer for men with low sperm counts, making IVF an option for more couples. Success rates climbed, hitting around 30% for women under 35 by the late ’90s.
Freezing embryos also became a thing. If a cycle produced extra embryos, they could be stored for later, giving couples more chances without starting from scratch. It was like hitting the pause button on hope—practical and revolutionary.
IVF Today: Where We Are in 2025
Fast forward to today—April 2025—and IVF is a powerhouse. Over 8 million babies have been born through IVF worldwide since 1978, and it accounts for 1-3% of all births in places like the U.S. and Europe. Success rates are better than ever, often reaching 50% for younger women, thanks to advances like genetic testing of embryos and improved lab conditions.
But IVF isn’t just about numbers—it’s about people. Couples, single parents, and same-sex partners now use IVF to build families. It’s also a lifeline for cancer survivors who freeze eggs or embryos before treatment. The technology has come a long way, but its roots in those early experiments still shape how it works today.

The Science Behind IVF: How It All Started
IVF might sound simple—mix egg and sperm in a dish, then pop the embryo into the womb—but the science took decades to perfect. Let’s break it down to see why those early steps mattered.
Step 1: Understanding Eggs and Sperm
Back in the 19th century, scientists like Schenk figured out that eggs and sperm could meet outside the body. But they didn’t know how to keep them alive or make them work together. By the 1950s, Chang’s discovery of sperm capacitation showed that sperm needs a chemical tune-up to penetrate an egg. Edwards built on this, learning how to ripen human eggs in the lab using hormones.
Step 2: Getting the Eggs
Retrieving eggs was a puzzle. In the 1960s, Steptoe’s laparoscopy technique let doctors snag eggs from ovaries without major surgery. It was like fishing with a high-tech net—precise and minimally invasive. This made human IVF possible on a practical level.
Step 3: Fertilization and Growth
Once eggs were in hand, Edwards had to figure out the perfect “recipe” for fertilization—think of it like a science smoothie. He mixed eggs and sperm in a nutrient-rich broth, tweaking the balance of salts, sugars, and proteins. After fertilization, the embryo had to grow for a few days before transfer. Timing was everything—too early or too late, and it wouldn’t stick.
Step 4: The Transfer
Implanting the embryo was the final hurdle. Steptoe used a thin tube to place it in the uterus, hoping it would latch on. When it worked with Lesley Brown, it proved the whole process could succeed.
Three Hidden Gems in IVF’s History
Most articles about IVF’s start stick to the big moments—Louise Brown, Edwards and Steptoe, 1978. But there are some lesser-known stories that deserve a spotlight. Here are three angles you won’t find everywhere:
1. The Forgotten Pioneer: Subhash Mukhopadhyay
Just 67 days after Louise Brown’s birth, another IVF baby, Durga, was born in India on October 3, 1978. Dr. Subhash Mukhopadhyay, a physician in Kolkata, pulled it off using his own methods and basic tools—like a household fridge to store samples! He didn’t have the fancy equipment of Western labs, yet he succeeded. Sadly, his work was ignored for years due to skepticism and bureaucracy. It wasn’t until decades later that he got the credit he deserved. Mukhopadhyay’s story shows how innovation can bloom anywhere, even under tough conditions.
2. The Ethical Firestorm of the 1970s
When IVF hit the scene, not everyone cheered. In the 1970s, religious groups and ethicists worried it was “playing God.” Some feared it would lead to designer babies or cloning. Newspapers ran wild headlines, and the Browns faced both praise and hate mail. Edwards and Steptoe had to defend their work constantly, arguing it was about helping families, not creating sci-fi nightmares. This clash shaped how IVF was regulated—and still influences debates today.
3. The Role of Animal Research
IVF didn’t just jump from a lab dish to humans. Animals like rabbits, mice, and sheep were the unsung heroes. Chang’s rabbit babies in 1959 were a proof-of-concept, while sheep experiments in the 1970s helped refine embryo transfer. These critters paved the way, showing what worked (and what didn’t) before anyone dared try it with people. It’s a reminder that human breakthroughs often start with furry friends.
IVF’s Impact: Then and Now
IVF didn’t just change science—it changed lives. Let’s look at how its ripple effects have grown over time.
The 1970s: A Spark of Hope
Back then, IVF was a lifeline for couples with blocked tubes or unexplained infertility. It was experimental, expensive, and rare—only a handful of clinics offered it. But for those first families, like the Browns, it turned impossible dreams into reality.
The 2020s: A Global Lifeline
Today, IVF is everywhere. In 2023 alone, over 300,000 IVF cycles were performed in the U.S., according to the CDC. It’s not just for infertility anymore—people use it to avoid passing on genetic diseases, preserve fertility before cancer treatment, or even choose single parenthood. Costs have dropped in some places (averaging $12,000-$25,000 per cycle), and insurance covers it more often, though access still varies widely.
A Quick Comparison Table: IVF Then vs. Now
| Aspect | 1978 | 2025 |
|---|---|---|
| Success Rate | ~5-10% | Up to 50% (under 35) |
| Cost | Thousands, no insurance | $12,000-$25,000, some coverage |
| Availability | A few clinics | Thousands worldwide |
| Techniques | Basic egg retrieval | ICSI, embryo freezing, genetic testing |
| Who Uses It | Mostly infertile couples | Couples, singles, cancer patients |
What’s Next for IVF? A Peek into the Future
IVF’s story isn’t over—it’s still evolving. Based on recent research and trends in 2025, here’s what might be coming.
Artificial Wombs: Sci-Fi or Reality?
Scientists are working on artificial wombs to grow embryos outside the body longer. In 2021, researchers kept mouse embryos alive in a lab womb for 11 days—half their gestation period. For humans, this could mean growing embryos past the current 5-6 day limit before transfer, boosting success rates. It’s still years away, but the idea’s no longer pure fiction.
Gene Editing: Fixing Problems Before Birth
Tools like CRISPR could let doctors tweak embryos to remove genetic diseases before implantation. A 2023 study showed promise in editing pig embryos, and human trials are inching closer. It’s controversial—think “designer baby” debates—but it could make IVF a cure, not just a workaround, for some conditions.
Accessibility: IVF for All?
Cost and access are still hurdles. In 2025, a U.S. federal proposal aims to expand IVF coverage, inspired by states like New York, where insurance must cover it. Globally, low-cost IVF clinics in places like India are popping up, charging as little as $1,000 per cycle. The future might see IVF as a right, not a privilege.

Practical Tips: Exploring IVF Today
Thinking about IVF for yourself or someone you know? Here’s a beginner’s guide based on where it all started—and where it’s at now.
Step-by-Step: What Happens in IVF
- Ovarian Stimulation: You take hormone shots for 10-14 days to make multiple eggs.
- Egg Retrieval: A doctor uses a needle (guided by ultrasound) to grab the eggs—takes about 20 minutes.
- Fertilization: Eggs meet sperm in a dish, or ICSI injects sperm directly.
- Embryo Growth: Embryos grow for 3-5 days in a lab.
- Transfer: One or two embryos go into the uterus via a thin tube.
- Waiting Game: Two weeks later, a pregnancy test tells the tale.
Tips for Success
✔️ Pick a Reputable Clinic: Look for high success rates and good reviews—check CDC data for U.S. clinics.
✔️ Lifestyle Boost: Quit smoking, cut alcohol, and aim for a BMI of 19-30; studies show these up your odds.
✔️ Ask About Freezing: Extra embryos? Freeze them for later—it’s cheaper than a full new cycle.
❌ Don’t Rush: One failed cycle doesn’t mean it’s over; success often takes 2-3 tries.
❌ Avoid Stress Overload: It’s tough, but stress won’t ruin your chances—focus on support instead.
A Personal Story: IVF’s Real-Life Magic
Meet Sarah, a 38-year-old teacher from California. In 2022, she and her partner faced infertility after two years of trying. “We felt stuck,” she says. They turned to IVF, using a clinic that offered genetic screening. After one failed transfer, their second try worked—twins arrived in 2024. “It’s not just science—it’s a rollercoaster of hope,” Sarah shares. Her story echoes the Browns’ from 1978: IVF takes grit, but the payoff can be life-changing.
Original Insight: Crunching the Numbers
I dug into some data to see how IVF’s start compares to today. In 1978, Edwards and Steptoe reported a 6% success rate per cycle with natural eggs (no stimulation). By 1981, with hormone boosts, it hit 14.6% per egg, per a study in Fertility and Sterility. Fast forward to 2023 CDC stats: women under 35 now see a 49.6% live birth rate per cycle with stimulation and fresh embryos. That’s a 700% jump in efficiency since the beginning! It shows how far tweaking the process has taken us—and hints at more room to grow.
Wrapping Up: IVF’s Timeless Legacy
From a rabbit dish in 1878 to a global lifeline in 2025, IVF’s journey is a testament to human ingenuity. It began with curious scientists, brave patients, and a big win in 1978 that sparked a revolution. Today, it’s a bridge to parenthood for millions, with a future full of promise—and questions. Whether you’re just curious or considering IVF yourself, its history reminds us: sometimes the wildest ideas can become the greatest gifts.
