Every year on July 25, the global medical community observes World Embryologist Day, also known as World IVF Day, to commemorate the birth of Louise Joy Brown, the world’s first baby conceived through in vitro fertilisation (IVF). Born on this date in 1978 in Oldham, England, Brown’s arrival marked a turning point in reproductive medicine, offering hope to millions of infertile couples worldwide. The day recognises not just her birth, but the relentless work of the scientists and embryologists who turned the dream of assisted reproduction into reality.
How IVF Happened: The Story of the Pioneers
The journey to the first successful IVF birth was the result of a collaboration between three individuals. Dr. Robert Edwards, a British physiologist, Dr. Patrick Steptoe, an obstetrician and gynaecologist, and Jean Purdy, a nurse and embryologist, worked together for nearly a decade to overcome scientific, funding, and ethical hurdles.
Edwards began studying human fertilisation in the 1960s at the University of Cambridge. In 1968, he successfully fertilised a human egg in the laboratory. Around the same time, he partnered with Steptoe, who had mastered the technique of laparoscopy, a minimally invasive surgical method to retrieve eggs from a woman’s ovaries. Jean Purdy joined as their research assistant and became the world’s first clinical embryologist. She was the first person to see the cells of a human embryo dividing under a microscope.
The team faced stiff opposition. The Medical Research Council (MRC) in the UK refused to fund their research in 1971, calling it experimental and controversial. Religious groups and sections of the media also criticised them. Despite over a hundred failed attempts, the team persisted.
In 1977, Lesley Brown, a woman whose blocked fallopian tubes had prevented natural conception, volunteered for the procedure. On 10 November 1977, doctors retrieved an egg from her ovary, fertilised it with her husband’s sperm in a Petri dish, and after several days of observing cell division, implanted the embryo back into her uterus. The pregnancy succeeded, and on 25 July 1978, Louise Joy Brown was delivered by caesarean section at Oldham General Hospital, weighing 2.6 kilograms.
Edwards was awarded the Nobel Prize in Physiology or Medicine in 2010 for developing IVF. Steptoe and Purdy were not eligible as the Nobel Prize is not awarded posthumously. Purdy’s critical contributions remained largely unrecognised for decades but have since been acknowledged through memorials, including a plaque at the Royal Oldham Hospital installed in 2022 and a memorial at the Bourn Hall Clinic.
IVF in India: A Story of Triumph and Tragedy
India’s tryst with IVF began soon after Louise Brown’s birth, but it was marked by controversy and personal tragedy. Dr. Subhash Mukhopadhyay, a physician from Kolkata, claimed to have created India’s first test tube baby, Kanupriya Agarwal (nicknamed Durga), on 3 October 1978, just 70 days after Louise Brown. Working with basic laboratory equipment, Mukhopadhyay achieved this feat independently.
However, instead of recognition, Mukhopadhyay faced hostility from the West Bengal government and the Government of India. A committee appointed to verify his claims refused to accept his achievement. Denied permission to attend international conferences and subjected to humiliation, Mukhopadhyay died by suicide on 19 June 1981 at the age of 50.
His contributions were recognised only posthumously, years later, after Dr. T. C. Anand Kumar reviewed his personal notes and confirmed the authenticity of his work. The Dictionary of Medical Biography now lists Mukhopadhyay among notable medical scientists. His story inspired the Hindi film Ek Doctor Ki Maut (1990), directed by Tapan Sinha.
India’s officially recognised first test tube baby project was later credited to Dr. Anand Kumar, who led the team that delivered India’s second IVF baby at the Institute for Research in Reproduction in Mumbai. Today, India is one of the world’s largest markets for IVF treatment, with hundreds of fertility clinics across the country.
The Global Impact of IVF: From One Baby to Millions
What began as a single experimental birth has grown into a global revolution in reproductive medicine. According to a study published in Fertility and Sterility in 2025, more than 13 million babies have been born through IVF and other assisted reproductive technologies (ART) worldwide since 1978. One ART-conceived baby is now born approximately every 35 seconds across the globe.
| Milestone | Detail |
|---|---|
| First IVF baby | Louise Joy Brown, born 25 July 1978, Oldham, UK |
| First IVF baby in India | Kanupriya Agarwal (Durga), born 3 October 1978, Kolkata |
| First IVF baby in the US | Elizabeth Carr, born 28 December 1981 |
| First IVF baby in Australia | Candice Reed, born 23 June 1983 |
| Global IVF births | More than 13 million (as of 2024) |
| Nobel Prize for IVF | Robert Edwards, 2010 (Nobel Prize in Physiology or Medicine) |
| Births per second | One ART baby every 35 seconds (2024 estimate) |
The success of IVF has led to further innovations such as intracytoplasmic sperm injection (ICSI), where a single sperm is injected directly into an egg, and preimplantation genetic diagnosis (PGD), which allows screening of embryos for genetic disorders before implantation.
Why Embryologists Matter
World Embryologist Day specifically honours the professionals who work behind the scenes in IVF laboratories. An embryologist is a specialist who handles eggs, sperm, and embryos in a laboratory setting. Their responsibilities include retrieving eggs from follicular fluid, fertilising them with sperm, monitoring embryo development, and preparing embryos for transfer into the uterus.
The role demands precision, patience, and a deep understanding of reproductive biology. Embryologists are also responsible for advanced procedures such as cryopreservation, the freezing of embryos and eggs for future use, and embryo biopsy for genetic testing. Without their expertise, the entire IVF process would not be possible.
The day also serves to raise awareness about infertility, a condition affecting an estimated one in every six people of reproductive age worldwide. Infertility can affect both men and women and has multiple causes, including blocked fallopian tubes, low sperm count, hormonal imbalances, and age-related decline in fertility.
