Bottom line up front: IVF add-ons vary enormously in evidence quality — some have reasonable supporting data for specific situations, while others are marketed more aggressively than their evidence base actually supports.
| Add-on | Evidence status |
|---|---|
| PGT-A (advanced maternal age) | Reasonable evidence for this specific population, covered in our dedicated article |
| Time-lapse embryo imaging | May aid embryo selection; evidence for improved live birth rates is mixed |
| Endometrial receptivity testing (ERA) | Evidence is evolving; may help specific patients with recurrent implantation failure |
| Assisted hatching | Limited evidence of benefit for most patients; more established for specific situations |
| Immunological testing/treatment | Evidence base is generally weak for most proposed interventions |
Why this matters for your decision-making
Add-ons add cost, and not all carry evidence proportional to that cost or to how they're sometimes marketed — ask your provider specifically what evidence supports a recommended add-on for your particular situation, not just in general.
A reasonable framework for evaluating any add-on
Ask: what specific evidence supports this for my specific situation, what does it cost, and what happens if I decline it? A provider should be able to answer all three clearly, via colombianivf.com or any clinic you're evaluating.
The Takeaway
Evaluate each add-on on its specific evidence for your specific situation — not every add-on offered is equally supported by data, regardless of how it's marketed.
