Yenra | Updated September 16, 2026
Guide: https://yenra.com/biotechnology-ethics/

Purpose: document an ethical assessment of a specific proposal. This worksheet
does not replace scientific, veterinary, institutional or regulatory review.
Copy each evidence row as needed. Record source dates and relevant jurisdictions.

1. DEFINE THE PROPOSAL
Reviewer / date:
Species, population and setting:
Alteration or reproductive method:
Purpose and proposed scale:
Baseline or alternative being compared:
People and animals affected across development, production and lifetime care:
Jurisdiction and responsible authorities:

2. RECORD THE EVIDENCE
For each dimension, enter:
  Claim:
  Source URL / date / study setting:
  Measured finding (with units, denominator and comparator when applicable):
  Forecast or assumption (keep separate):
  Uncertainty or missing evidence:
  Who bears the benefit or burden:
  Required follow-up and responsible person:

Apply this row to all six dimensions:
  A. Benefits: magnitude, distribution, durability and confidence.
  B. Welfare: all procedures, failed attempts, health, behavior and lifetime care.
  C. Environment: containment, escape, reproduction and ecological interactions.
  D. Alternatives: feasible ways to meet the same purpose with fewer burdens.
  E. Fairness: access, costs, profits, consent and participation in decisions.
  F. Oversight: authority, independent review, transparency and ability to stop.

3. APPLY THE 3Rs TO RESEARCH INVOLVING ANIMALS
Replacement: which suitable non-animal approaches were considered?
Reduction: how does the design obtain reliable information with appropriate use?
Refinement: how will pain, distress or lasting harm be reduced and assessed?
Include breeding, housing, handling, procedures, endpoints and aftercare.

4. CHECK REGULATORY SCOPE
Exact product or activity covered:
Authority, document title, date and URL:
Document type: legislation / guidance / product decision / proposal:
Intended use and conditions:
Questions outside the document's scope:
Local requirements needing qualified review:

5. WRITE THE DECISION
Conclusion and strongest reason:
Strongest counterargument:
Unresolved factual disagreement:
Unresolved value disagreement:
Conditions, evidence needed and limits:
Monitoring measure / responsible owner / intervention threshold:
Review date or event:
What finding would change the decision?

ILLUSTRATIVE CASE -- FICTIONAL, NOT A REAL PRODUCT ASSESSMENT
A developer proposes an alteration intended to reduce viral disease in pigs.
Check illness outcomes against suitable controls, then examine growth,
reproduction, behavior, other health effects and all animals used in development.
Compare feasible disease-control and husbandry alternatives. Ask who funds
follow-up and whether production incentives change how the animals are kept.
A conclusion may require further bounded evaluation or reject the proposal;
state the assumptions and missing evidence that drive that judgment.

Regulatory compliance and ethical evaluation address overlapping but distinct
questions. Keep the scope of each conclusion explicit.
