World IVF Day marks the birth of the world’s first IVF baby and celebrates the remarkable advances in assisted reproductive technology. Today, IVF continues to help millions of people overcome infertility.
- In vitro fertilization (IVF) has helped millions of people achieve pregnancy and become parents worldwide
- Success rates depend on factors such as age, egg quality, sperm health, and the underlying cause of infertility
- Early fertility evaluation and timely treatment can improve the chances of a successful pregnancy
Infertility affects millions of couples across the world, yet it remains surrounded by myths, stigma, and emotional challenges. In 2021, an estimated 55,000,818 men and 110,089,459 women were living with infertility worldwide (1). For many people, the dream of becoming parents feels uncertain after months or even years of trying to conceive naturally. Fortunately, advances in reproductive medicine have transformed this journey. On World IVF Day, observed every year on July 25, healthcare professionals celebrate one of the greatest milestones in modern medicine that has helped millions of families welcome healthy babies.
World IVF Day commemorates the birth of Louise Brown in 1978, the world’s first baby conceived through in vitro fertilization (2). Since then, IVF has evolved into one of the most successful fertility treatments available today. According to the European Society of Human Reproduction and Embryology (ESHRE), millions of babies have now been born through assisted reproductive technologies (ART) worldwide. Ever since the first ART-conceived infant was born in 1978, ten million and up to 13 million or more infants have been born from ART in 40 years (3). IVF continues to offer hope to individuals and couples facing infertility while becoming safer and more effective with advancing technology.

What Is IVF and How Does It Work?
In vitro fertilization, commonly known as IVF, is an assisted reproductive technology in which eggs are collected from the ovaries and fertilized with sperm in a specialized laboratory (4). Once fertilization occurs, the resulting embryo is carefully monitored before being transferred into the uterus to establish pregnancy. If implantation is successful, the pregnancy progresses naturally like any other conception.
The IVF process involves several carefully planned stages, including ovarian stimulation, egg retrieval, fertilization, embryo culture, and embryo transfer. Some couples may also choose embryo freezing for future use. Each treatment plan is personalized according to the couple’s medical history, fertility evaluation, and reproductive goals.

Who Can Benefit From IVF Treatment?
IVF is recommended for several fertility conditions affecting either partner. Women with blocked fallopian tubes, ovulation disorders, endometriosis, diminished ovarian reserve, or unexplained infertility may benefit from IVF. Men with low sperm count, poor sperm motility, or other male fertility issues may also be candidates for assisted reproductive treatment (4).
IVF is increasingly helping single parents by choice, same-sex couples, and individuals choosing fertility preservation before cancer treatment. Modern reproductive medicine has expanded treatment options beyond traditional infertility care. Early fertility assessment allows doctors to recommend the most appropriate treatment before fertility declines further with age.

What Determines IVF Success Rates?
Many people believe IVF guarantees pregnancy, but success depends on several biological and medical factors. A woman’s age remains one of the strongest predictors because both egg quality and quantity gradually decline over time (5). Embryo quality, sperm health, uterine conditions, lifestyle habits, and underlying medical disorders also influence treatment outcomes (6).
According to the American Society for Reproductive Medicine, IVF success rates are generally higher among younger women, although advances in embryo selection and laboratory techniques continue to improve outcomes across different age groups. Maintaining a healthy lifestyle, managing body weight, avoiding smoking, and following medical advice may further improve the chances of pregnancy (7).
How Has IVF Changed Fertility Care?
Since the birth of the world’s first IVF baby, fertility medicine has witnessed remarkable scientific progress. Technologies such as intracytoplasmic sperm injection, embryo freezing, blastocyst culture, preimplantation genetic testing, and time-lapse embryo monitoring have significantly improved precision and success rates (8). These innovations have also reduced multiple pregnancies by encouraging single embryo transfer in appropriate patients.
Researchers continue to explore artificial intelligence, advanced embryo selection methods, and personalized fertility treatment to further improve outcomes. IVF is now considered a well-established and evidence-based fertility treatment that continues to evolve with scientific research and clinical experience.
Common IVF Myths You Should Stop Believing
Many misconceptions continue to discourage people from seeking fertility treatment. IVF does not always result in multiple pregnancies because modern clinics increasingly transfer a single healthy embryo whenever appropriate. Another common myth is that infertility affects only women, whereas male factors contribute to nearly half of infertility cases.
Some people also believe IVF should only be considered after many years of infertility. Fertility specialists emphasize that timely evaluation can improve treatment options and outcomes, especially for women above 35 years. Seeking help early can make a meaningful difference in achieving a successful pregnancy.
World IVF day 2026
World IVF Day celebrates one of the most remarkable achievements in reproductive medicine while raising awareness about infertility and available treatment options. IVF has helped millions of families worldwide overcome fertility challenges through decades of scientific innovation and compassionate care. If you have been trying to conceive without success, speaking to a fertility specialist early can help identify the cause and guide you toward the most suitable treatment pathway.
