Why age limits exist in some jurisdictions
Some countries impose age caps as a matter of policy, reflecting views on appropriate parental age or resource allocation — these are legal/regulatory limits, distinct from the clinical success-rate decline covered elsewhere on this network.
Why this varies so much by country
Age caps, where they exist, vary considerably by jurisdiction and specific circumstance — verify the current specific limit for any destination you're considering directly, since this is exactly the kind of regulatory detail that can change.
Colombia's approach
Colombia does not impose a specific statutory age cap on IVF treatment in the way some jurisdictions do, though individual clinics may apply their own clinical judgment regarding a specific patient's candidacy — a distinction between legal limits and clinical judgment worth understanding.
See colombianivf.com for current, clinic-specific guidance on this question.
The Takeaway
If age is a relevant factor for you, verify both the legal limit (if any) and the individual clinic's clinical judgment directly — these are two distinct considerations.
