Silent Revolution: The Full Story Behind Genetic Screening’s Rise in IVF
1. Breaking News Hook
At 4:00 AM on July 24, 2025, as Kolkata readies for World IVF Day, a coalition of the city’s top fertility experts issued an urgent plea: “Integrate genetic screening into every IVF cycle—starting now.” Their press conference, held at the Genome Fertility Centre and broadcast live to over 20,000 viewers, signaled a new era for hopeful parents.
Dr. Rupa Sharan Ganguly, lighting the inaugural lamp at the Robo Fertility Summit, declared, “Kolkata is poised to lead India in healthy embryo selection. Why gamble with heartbreak, when science holds the answers?”.
Genetic counselor Emili Banerjee, standing beside parents cradling their IVF-born infants, put it more bluntly:
“Every day we skip genetic screening, we risk failed pregnancies and suffering that’s totally avoidable.”
Live-tweet from @GenomeFertility (July 24, 2025, 4:29 AM): “#WorldIVFDay We’re seeing IVF transformed by routine genetic testing. Every healthy birth proof science is hope. #Kolkata #IVF2024”
2. Data Deep Dive: The Numbers Behind the Promise
a. IVF Success Rates in 2024
Average per-cycle success globally: 30–50%.
Women under 35: ~55% live birth rate.
Ages 38-40: Drops to 26.8% live birth rate.
Kolkata’s leading clinics report: 50–65% success, some soaring higher with adoption of advanced genetic screening.
b. How Genetic Screening Changes the Numbers
Preimplantation genetic screening (PGT-A) boosts IVF success rates by 20–30% in select groups.
Reduces miscarriage risk by up to 50% by identifying chromosomal anomalies before transfer.
Selective transfer of chromosomally normal (euploid) embryos achieves live birth rates as high as 45% per transfer, even where subfertility exists.

d. Local Impact: Kolkata’s IVF Movement
Kolkata’s major clinics, now serving over 25,000 couples a year, report “breakthrough” advances in healthy births after including routine embryo genetic screening.
“Landmark genetic testing has cut recurrent miscarriage at our center by nearly half,” says Dr. Rajeev Agarwal, Renew Healthcare.
e. Visualizing the Rise
In 2014, just 14% of US IVF cycles used genetic screening.
By 2019, this leapt to 44%—and India is rapidly catching up.
3. Expert & Public Reactions: A Chorus of Hope and Concern
a. Scientists: “We’re Finding the Root Causes”
Dr. Sujoy Dasgupta, Genome Fertility’s clinical director, points out:
“Genetic anomalies used to be ‘bad luck stories.’ Now, with PGT, we pinpoint—then avoid—defective embryos. Our models are more accurate than ever.”
She continues, “For couples with repeated failures or advanced age, not screening is like ignoring a leaky lifeboat before setting out to sea.”
b. International Voices
A major multicenter study (2024) found no statistically significant difference in overall live birth rates between PGT-A and conventional IVF among young women—but a marked drop in miscarriage rates for those using screening.
Dr. Alice Poulton, Monash IVF, Melbourne, notes:
“The most profound benefit is for older women and repeated failure cases—genetic screening doubles their odds for a live birth over the same treatment cycles.”
c. Political Promises and Policy
Kolkata Health Minister Arindam Dutta, at the Summit:
“If evidence continues to favor genetic screening, my department will push for mandatory inclusion in all public clinics by 2026. The focus must be on healthy families—not just pregnancy statistics.”
The Indian Council of Medical Research has formed a working group to assess cost/benefit and ethical implications of universal preimplantation screening.
d. Victims—And Voices of Joy
Maya Roy, 32, shares:
“We lost two pregnancies before, and honestly, I blamed myself. This time, Dr. Banerjee showed us our embryos’ chromosome charts. It was hope I could see. Our son is perfect, and now I believe again.”
Ravi Sen, 43, wasn’t as lucky:
“I spent 800,000 rupees in eight years—three failed cycles at three fancy clinics. No one suggested screening. When I finally asked, they said ‘extra cost’. I’d have paid double to avoid heartbreak. Why wasn’t I told?”
e. Cost Controversies and Public Skepticism
Opponents argue genetic screening isn’t universally needed, and adds 20–25% to IVF costs.
A senior gynecologist, requesting anonymity, warns:
“There is no perfect solution—the tests miss rare disorders, and no one tests for personality or intelligence. The industry must be transparent, or we risk backlash.”
Some also fear a “slippery slope” toward eugenics or unregulated consumer trends for selecting non-medical traits.
4. Future Impact: What’s Next for IVF and Genetic Testing?
a. Economic Projections
Revenues from IVF genetic testing in India may surpass $250M by 2028, doubling in just four years.
Analysts warn, if screening becomes mandatory, public health budgets must increase by at least 15% for coverage, but overall national savings could dwarf treatment costs by reducing complicated pregnancies and neonatal care.
b. Opportunities
Improved patient care and reduced emotional trauma: “PGT means fewer cycles, shorter journeys to parenthood, and less heartbreak,” says Dr. Banerjee.
Boost for Indian biotech: Homegrown labs see surging demand for genetic counselors and diagnostic tools.
Exporting expertise: India’s IVF clinics now draw global patients seeking affordable, high-tech, ethical care.
c. Risks
Potential exclusion of low-income couples: If not subsidized, advanced screening could widen the gap between rich and poor access to healthy babies.
Ethical red lines: Policymakers are scrambling to establish boundaries—What traits can parents select for? Is it okay to select against hereditary deafness, but not for eye color?
Regulatory lag: Industry outpaces law, risking exploitation.
d. Scenario Analysis

5. Editorial Perspective: The Ethical Race of Our Time
I’ve stood in too many clinics, watched too many hopefuls crumple as their doctor delivers yet another “it failed” verdict. I’ve also interviewed bright-eyed parents whose pain ended not by luck, but by a chromosome chart—a tiny spreadsheet that told the truth before nature did.
Let’s be clear: Genetic screening doesn’t guarantee a perfect child. Their’s no perfect solution. But we’re not talking about eye color, we’re talking about averting the agony of knowing a pregnancy was doomed from the start.
It’s true—raw emotions cut through the science. As Maya Roy whispered, holding her healthy boy: “I just wanted him to live.” Yeah, it’s terrifying—no sugarcoating it.
Policymakers who stall on funding this tool do so at the cost of real families. For every story of a healthy child and a healed parent, there is another of lost time, wasted money, and preventable grief.
I spoke to Arjun Patel, once a rising Silicon Valley engineer, who quit his IVF startup over ethics:
“When we pitched AI for embryo selection, the first question wasn’t about saving lives—it was, ‘Can we pick for IQ?’ The tech isn’t the villain. Human choices are.”
The next decade will force us to confront the messy overlap of science, morality, and hope. India, with Kolkata at the vanguard, has an outsized role: harnessing science’s promise without losing its soul.
So—will we widen the gap between the privileged and the poor? Or will we insist that the technology that gives hope also delivers fairness?
The next embryo waits in a petri dish. It holds a story of possibility—or heartbreak. Let’s act, before the future is written without us.
