New Lancet Study Questions IVF Add-Ons. What Actually Improves Success Rates in Colombia Surrogacy?
Every year, intended parents spend thousands of dollars on IVF add-ons that promise to improve their chances of success.
Acupuncture.
Intralipid infusions.
PRP treatments.
Immune therapies.
ERA testing.
The list continues to grow.
But a major 2026 review published in The Lancet Obstetrics, Gynaecology & Women’s Health has once again raised an uncomfortable question:
How many of these treatments actually improve the chances of taking home a healthy baby?
After reviewing dozens of studies involving IVF add-ons, researchers concluded that many commonly marketed treatments either lack strong evidence or have not consistently demonstrated improvements in live birth rates.
For intended parents considering IVF or surrogacy, the findings reinforce an important reality:
Success is usually determined by fundamentals rather than expensive extras.
And nowhere is this more relevant than in international surrogacy.
The Biggest Misunderstanding About Colombia Surrogacy
Many people exploring Colombia surrogacy assume that success depends on finding the newest treatment or the latest fertility trend.
In reality, most experienced embryologists would tell you something very different.
The strongest predictors of success remain remarkably consistent:
- Maternal age at the time embryos were created
- Embryo quality
- Laboratory performance
- Endometrial preparation
- Transfer technique
- Surrogate health
These factors influence outcomes every single day.
Most add-ons do not.
Why Laboratory Quality Matters More Than Most Add-Ons
For international intended parents, the embryo is often the most valuable asset in the entire journey.
Many families arrive with embryos already created in:
- The United States
- Canada
- Australia
- The United Kingdom
- Europe
Once those embryos arrive in Colombia, laboratory quality becomes critical.
The best embryo in the world can be compromised by poor laboratory procedures.
Conversely, a well-managed laboratory can maximize the potential of every embryo transferred.
As an embryologist, I have always believed that laboratory quality control has a far greater impact on success rates than many add-on treatments marketed to fertility patients.
The American-Standard Model Emerging in Colombia
One reason Colombia has become increasingly attractive for international intended parents is that some fertility centers have adopted operational standards that closely mirror those used in North America.
This includes:
- Modern embryology laboratories
- U.S.-style quality control systems
- International cryopreservation protocols
- Comprehensive documentation procedures
- Advanced embryo vitrification techniques
At the Bogotá fertility clinic where Canbaby Surrogacy coordinates many international cases, the IVF program is supported by American investment and follows laboratory procedures designed around U.S. clinical standards.
For many families, this creates a unique combination:
American-level laboratory systems paired with significantly lower overall treatment costs than those typically found in the United States.
The Surrogate Matters More Than the Add-On
Another lesson often overlooked in online fertility discussions is the importance of surrogate screening.
The healthiest embryo still requires a healthy pregnancy.
In Colombia, high-quality surrogate programs typically focus on:
- Proven pregnancy history
- Psychological evaluation
- Medical screening
- Lifestyle assessment
- Ongoing prenatal care
These factors have a direct impact on pregnancy outcomes.
No amount of acupuncture or immune therapy can compensate for poor surrogate selection.
The Real Formula Behind Successful Colombia Surrogacy
When intended parents ask what truly improves success rates, the answer is usually not very exciting.
It is not a miracle injection.
It is not a secret protocol.
It is not the newest fertility trend on social media.
Success is built on:
- High-quality embryos
- Experienced embryologists
- Reliable laboratory systems
- Proper endometrial preparation
- Carefully screened surrogates
- Strong legal coordination
- Consistent medical follow-up
These fundamentals continue to outperform most fertility add-ons.
What This Means for Intended Parents
The latest Lancet review does not suggest that every IVF add-on is useless.
Some treatments may still have value for specific patients under specific circumstances.
However, the study serves as a useful reminder that intended parents should focus their resources on the factors that consistently influence outcomes.
For families considering Colombia surrogacy, that means prioritizing:
- Embryo quality
- Laboratory standards
- Surrogate screening
- Medical oversight
- Legal protection
before spending heavily on treatments with limited supporting evidence.
The Canbaby Surrogacy Perspective
At Canbaby Surrogacy, we believe successful outcomes are built on science, not marketing.
As an embryologist-led team, we focus on the elements that have the greatest influence on success:
safe embryo transportation, laboratory quality, surrogate selection, medical coordination, and legal planning.
Because in international surrogacy, the goal is not simply to achieve a positive pregnancy test.
The goal is to bring home a healthy baby.
And that journey starts long before transfer day.
