Every year on July 25, the global medical and scientific community observes World IVF Day, also recognised as World Embryologist Day, to mark the birth of Louise Joy Brown in 1978 — the first child conceived through in vitro fertilisation (IVF). World Embryologist Day honours the scientists and lab professionals whose embryology work makes IVF possible.This date is recognised internationally as a milestone in reproductive medicine and serves as an annual platform for raising awareness about infertility as a clinically significant condition affecting approximately 17.5% of adults worldwide, according to the World Health Organisation.
Infertility remains underdiagnosed and undertreated across large parts of India. ICMR estimates indicate that 10–14% of Indian married couples experience infertility, with both male and female factors contributing in nearly equal proportion. Despite this prevalence, diagnostic evaluation is frequently delayed by years, a gap that directly reduces the effectiveness of available treatment options. Understanding the history of IVF, the science behind it and the diagnostic foundations that support it is essential for patients, families and healthcare professionals alike.
The History Behind World IVF Day
The development of IVF was the result of over two decades of research led by Dr. Robert Edwards (physiologist, University of Cambridge), Dr. Patrick Steptoe (gynaecologist) and Nurse Jean Purdy — whose contribution was historically underrecognised until recent years.
Key milestones in IVF history:
- 1960s: Dr. Edwards began pioneering research into human egg fertilisation outside the body, facing significant institutional resistance and funding challenges
- 1968: Dr. Edwards and Dr. Steptoe began their formal collaboration, combining laboratory fertilisation techniques with laparoscopic egg retrieval
- July 25, 1978: Louise Joy Brown was born at Oldham General Hospital, England — the first child conceived through IVF, after 102 failed embryo transfers across multiple patients
- October 3, 1978: Kanupriya Agarwal (known as "Durga") was born in Kolkata — India's first and the world's second IVF baby, delivered through the work of Dr. Subhash Mukhopadhyay, Prof. Sunit Mukherji and Dr. Saroj Kanti Bhattacharya. This achievement came just 67 days after Louise Brown's birth.
- 2010: Dr. Robert Edwards was awarded the Nobel Prize in Physiology or Medicine for the development of IVF
Since 1978, IVF and related assisted reproductive technologies have resulted in the birth of over 10 million children worldwide. India today has one of the largest IVF ecosystems globally, with fertility services available across Ahmedabad, Mumbai, Kolkata, Surat, Jaipur, Vadodara, Hyderabad, Indore, Siliguri, Srinagar, Jamnagar and hundreds of smaller cities.
Why World IVF Day and World Embryologist Day Matter: The Clinical Importance of Awareness
World IVF Day serves multiple clinical and public health objectives:
- Normalising infertility as a medical condition: Infertility continues to carry social stigma in many communities, leading to delayed diagnosis and missed treatment windows
- Promoting early diagnostic evaluation: Clinical evidence consistently demonstrates that earlier fertility assessment leads to better treatment outcomes. Evaluation should begin within the first 12 months of unsuccessful conception (6 months for women aged 35 and above)
- Recognising the role of diagnostics: IVF outcomes are directly influenced by the quality and timing of pre-treatment diagnostic workups. Accurate baseline blood tests form the foundation of every evidence-based fertility treatment plan
- Honouring scientific advancement: This is the core purpose of Embryologist Day — acknowledging the researchers, embryologists, clinicians and laboratory professionals whose work has made modern reproductive medicine possible. Embryologist Day specifically recognises the precision lab work behind every successful IVF cycle.
The Role of Fertility Blood Tests in IVF?
Before any IVF cycle is initiated, a comprehensive set of blood-based diagnostic tests must be completed. These tests assess ovarian reserve, hormonal regulation and reproductive physiology — providing the data required for individualised stimulation protocols and realistic outcome projections.
Essential Pre-IVF Hormone Tests:
- Anti-Müllerian Hormone (AMH): The most reliable single blood marker of ovarian reserve. AMH levels indicate the approximate number of remaining follicles and predict the likely response to ovarian stimulation medications. Low AMH values do not preclude pregnancy but significantly influence protocol design. Book AMH Test at Unipath
- Follicle-Stimulating Hormone (FSH): Elevated Day 2/3 FSH levels suggest diminished ovarian reserve. Routinely ordered alongside AMH for a comprehensive ovarian function assessment. Book FSH Test
- Luteinising Hormone (LH): The FSH-to-LH ratio is diagnostically significant, particularly in polycystic ovarian syndrome (PCOS) where LH is frequently disproportionately elevated relative to FSH. Book LH Test
- Beta hCG (Human Chorionic Gonadotropin): The definitive blood test for confirming pregnancy following IVF embryo transfer. Quantitative Beta hCG measurement, typically performed 10–14 days post-transfer, is significantly more accurate than urine-based pregnancy tests and enables monitoring of early pregnancy viability through serial measurements. Book Beta hCG Test
Additional Pre-IVF Investigations:
- Thyroid profile (TSH, T3, T4) — thyroid dysfunction directly affects ovulation and implantation
- Prolactin levels — hyperprolactinaemia can suppress ovulation
- Complete blood count and blood sugar — baseline metabolic health assessment
- Vitamin D — emerging evidence links deficiency to reduced IVF implantation rates
All fertility hormone tests are available at Unipath Specialty Laboratory across NABL-accredited facilities in Ahmedabad, Surat, Vadodara, Jamnagar, Kolkata, Jaipur, Siliguri and Srinagar.
IVF Success Rates: What the Clinical Data Shows?
IVF success rates vary significantly based on patient age, the underlying cause of infertility, embryo quality and the laboratory and clinical standards of the treating centre. Published data from international registries provides the following age-stratified benchmarks for live birth rates per cycle:
- Under 35 years: 40–55% per cycle. Ovarian reserve is typically adequate, egg quality is generally high and implantation rates are favourable.
- 35 to 37 years: 30–40% per cycle. Ovarian reserve markers (AMH, FSH) become increasingly critical in determining stimulation intensity.
- 38 to 40 years: 20–30% per cycle. The decline reflects diminishing egg quality and quantity. Multiple cycles are more frequently required.
- Over 40 years: Below 15% per cycle with autologous (own) eggs. This reflects biological limitations in oocyte quality rather than clinical competence.
A critical point for patient understanding: IVF success is cumulative across cycles. A 35% per-cycle live birth rate does not equate to a 65% failure rate. Over three to four cycles, cumulative success rates for patients under 38 frequently exceed 70%.
Addressing Common Misconceptions About IVF
Clinical practice is frequently undermined by persistent misconceptions about IVF. The following require direct correction:
- "IVF always results in multiple pregnancies." Modern IVF practice has shifted toward elective single embryo transfer (eSET) to reduce the medical risks associated with twin and higher-order pregnancies. Multiple pregnancy is now the exception in well-regulated centres.
- "IVF-conceived children have health or developmental differences." Decades of follow-up data involving millions of IVF-conceived individuals show no clinically meaningful differences in physical, cognitive or developmental outcomes compared to naturally conceived children.
- "Infertility is exclusively a female condition." Male-factor infertility contributes to approximately 40–50% of all infertility cases. Comprehensive evaluation must include semen analysis and hormonal assessment of the male partner.
- "Fertility testing is only relevant for IVF candidates." Baseline hormone tests (AMH, FSH, LH, thyroid profile) are clinically valuable for any individual planning conception. These tests identify treatable conditions such as PCOS, premature ovarian insufficiency and thyroid dysfunction — many of which respond to targeted treatment without requiring IVF.
When Should Fertility Evaluation Be Initiated?
Standard clinical guidelines recommend initiating a formal fertility workup under the following circumstances:
- Conception has not occurred after 12 months of regular unprotected intercourse (women under 35)
- Conception has not occurred after 6 months of regular unprotected intercourse (women aged 35 and above)
- Irregular or absent menstrual cycles at any age
- Known conditions such as PCOS, endometriosis or prior pelvic surgery
- History of recurrent pregnancy loss
- Male partner with known reproductive concerns (varicocele, prior chemotherapy, hormonal imbalance)
- Family history of premature menopause or ovarian insufficiency
The initial step in most fertility evaluations is a hormone blood panel. Unipath Specialty Laboratory provides AMH, FSH, LH and Beta hCG testing under NABL-accredited protocols with same-day report delivery for most panels. Accurate baseline hormone values at the outset of evaluation reduce diagnostic uncertainty and enable fertility specialists to build treatment plans grounded in laboratory data rather than clinical assumption.
