Overview
IVF treatment has changed dramatically over the last four decades. Once an experimental method with low chances of success at the time, it has now become one of the most successful and effective fertility treatments to date. The latest advancements in IVF and overall medical technology and research have contributed to higher success rates, safer procedures for the patient, lower risks associated with the procedure, and more personalised procedures.
The constant development of fertility drugs, embryology labs, embryo culture, genetic screening, cryopreservation methods, and artificial intelligence has driven the evolution of IVF. Thus, modern IVF provides more chances for infertile couples dealing with various infertility problems, with treatment being safer and more individualised.

Introduction
The history of IVF represents one of the most significant achievements in reproductive medicine. Ever since the first IVF baby was born in 1978, there has been continuous improvement at each stage of the procedure carried out by fertility experts and scientists.
There has been great improvement in IVF over the years owing to advances in science, improvements in lab techniques, embryo assessment, and patient care. The contrast of “old IVF vs modern IVF” is seen through the success rates obtained from new IVF techniques. Understanding IVF then and now, and its current state, allows us to see the tremendous progress made in fertility care.
The Birth of IVF
The history of IVF began in 1978 with the birth of the first test tube baby, whose name was Louise Brown. Fertilisation of an egg cell outside the human body before implanting it into the uterus became possible.
Despite the great success of the discovery, the initial stages of using IVF entailed some challenges. At that time, medical specialists did not have enough knowledge about embryos' development, ovary stimulation, and laboratory conditions. Many courses of treatment did not give any results; pregnancies occurred rarely.
However, the birth of the first test-tube baby became the beginning of further research.
IVF in the Early Years
During the initial years,IVF treatment was considerably different from what patients experience today.
Lower Success Rates
The success rate was fairly low since the fertility doctors had few options for treatments, little experience, and insufficient laboratory facilities.
Limited Technology
Imaging techniques such as ultrasounds, hormone monitoring, and other lab equipment were not as sophisticated as they are today, making it challenging for them to develop effective procedures.
Basic Embryo Culture
Early embryo culture techniques provided the minimal environment necessary for the survival of embryos. Experts had not yet created specialised media closely similar to the body's reproductive environment.
Major Breakthroughs That Changed IVF
The latest advancements in IVF technology have been revolutionary, thanks to constant developments in each step of the process.
Better Fertility Medications
Current-day fertility drugs ensure better ovarian stimulation with reduced chances of developing side effects such as OHSS. Tailoring the drug dosage for individuals ensures better results and even enhances egg quality.
Advanced Embryology Laboratories
Current-day embryology labs ensure that their environment is highly controlled, with regulation of factors like temperature, humidity, and gases for optimum development of embryos.
Improved Embryo Culture Media
Embryo culture media used today have been developed with the nutritional requirements of embryos at different stages of development in mind.
Blastocyst Culture
Instead of transferring embryos after only a few days, many IVF cycles now allow embryos to develop to the blastocyst stage before transfer. Blastocyst culture helps specialists identify embryos with greater developmental potential and can improve implantation rates in appropriately selected patients.
Frozen Embryo Transfer (FET)
Due to improvements in vitrification, a form of ultra-fast freezing, the survival rate of embryos following thawing has greatly improved. Frozen Embryo Transfer (FET) makes it possible to transfer the embryos at a later menstrual cycle, thus allowing a better uterine environment.
ICSI for Male Infertility
Intracytoplasmic Sperm Injection (ICSI) has brought a revolution in treatment options available for severe male factor infertility. In the ICSI procedure, the mature egg is injected with one healthy sperm (carefully screened with cutting-edge technologies).
Preimplantation Genetic Testing (PGT)
Preimplantation Genetic Testing (PGT) is a procedure in which embryos can be screened for particular chromosomal abnormalities or genetic conditions before transfer.
Time-Lapse Embryo Monitoring
Time-lapse incubator systems continuously monitor embryo development without removing embryos from the controlled laboratory environment. This allows embryologists to observe developmental patterns while minimising disturbance.
AI-Assisted Embryo Selection
In recent years, there has been an increasing trend of applying artificial intelligence to analyse images and developmental traits of embryos. AI-assisted analysis gives more data, which can help embryologists in embryo selection.
How IVF Has Become Safer
One of the key features of the evolution of IVF is its safety enhancement.
Fewer Multiple Pregnancies
Improvements in embryo selection techniques encourage the practice of single embryo transfer in suitable patients, avoiding twin pregnancy or higher-order pregnancies while maintaining high chances of pregnancy success.
Better Ovarian Stimulation
The use of customised stimulation methods, hormonal testing, and new drugs has minimised the occurrence of side effects due to the treatment, including OHSS.
Improved Patient Care
Patients receive full medical testing for infertility issues, customised care options, high-standard labs, and constant supervision throughout the IVF procedure.
Better Success Rates Today
When discussing conventional IVF vs advanced IVF, it can be seen that over the years, success rates have improved by leaps and bounds. There have been several reasons for this rise in success rates, which include:
- More advanced methods for embryo cultivation
- More favourable lab conditions
- More advanced cryopreservation methods
- Improved methods of hormonal level evaluation
- More personalised ovarian stimulation treatments
- More advanced embryo selection processes
- More knowledge of reproductive medicine
By no longer taking a blanket approach to IVF treatment, specialists can tailor their treatment to take into consideration age, ovarian reserve, fertility condition, prior experience, and general reproductive health.
What the Future of IVF Looks Like
The future of reproductive medicine will continue building on the rich history of IVF.
Artificial Intelligence
AI will help with embryo evaluation, treatment planning, and decision-making through analysis of large amounts of reproductive data.
Precision Medicine
Future IVF protocols will be more personalised through the use of genetic, hormonal, and clinical data to tailor treatment to the patient.
Fertility Preservation
Development in the field of egg, sperm, and embryo cryopreservation will increase the number of options available for patients with plans of delayed parenthood and patients who are going to undergo treatments that might affect their fertility.
Non-Invasive Embryo Assessment
Scientists have been working on the development of non-invasive techniques that can evaluate embryos based on substances they release into the culture media.
