Ethical monitoring of ovum pick-up procedures in domestic horses: A standardised self-assessment checklist for responsible veterinary practice.

Abstract: Assisted reproductive technologies (ARTs) have the potential to accelerate genetic improvement in selective equine breeding programmes while addressing specific reproductive challenges. One recent assisted reproductive technique in domestic horse breeding is Ovum Pick-Up combined with Intracytoplasmic Sperm Injection (OPU-ICSI). Despite their advantages, the implementation of these new procedures, like more established breeding methods, raises ethical concerns relating to aspects like animal welfare, staff safety, professional and veterinary practice integrity, which must be monitored and assessed. In this paper, we propose and discuss an ethical checklist for self-assessment to ensure that OPU procedures are conscientiously performed and monitored from an ethical standpoint. Based on three key ethical dimensions - Animal welfare ethics, Professional ethics, and Procedural ethics - the checklist has been developed and tested through an iterative process involving a panel of 14 experts, both in OPU procedures and applied ethics. The checklist is designed to achieve several objectives, including reducing procedural risks and protecting animal welfare, while the self-assessment approach enables the professionals involved to highlight potential issues that might otherwise be overlooked in daily practice and ensure that OPU procedures adhere to the highest ethical standards.

Plain Language Overview

  • This research article introduces a standardized ethical self-assessment checklist for veterinarians conducting ovum pick-up (OPU) procedures in domestic horses.
  • The checklist aims to promote responsible veterinary practice by ensuring that animal welfare, staff safety, and professional integrity are carefully monitored during these assisted reproductive techniques.

Detailed Explanation of the Research Article

Context and Background

  • Assisted Reproductive Technologies (ARTs) are increasingly used in horse breeding to accelerate genetic improvements and overcome reproductive challenges.
  • One advanced ART is Ovum Pick-Up combined with Intracytoplasmic Sperm Injection (OPU-ICSI), a technique that allows retrieval and fertilization of oocytes outside the mare’s body.
  • While OPU-ICSI presents several advantages in selective breeding, its implementation raises ethical concerns.
  • These concerns mainly involve three areas: animal welfare, safety of veterinary staff, and professional/veterinary integrity and practice standards.

Need for Ethical Monitoring

  • New and complex procedures such as OPU-ICSI require conscientious monitoring to ensure ethical standards are maintained.
  • Without formal, continuous assessment, there is a risk that critical ethical issues might be overlooked during routine veterinary practice.
  • Ensuring ethical conduct is essential both for the welfare of horses and the credibility of veterinary professionals.

Development of the Ethical Checklist

  • The authors created a standardized ethical self-assessment checklist tailored specifically for OPU procedures in horses.
  • The checklist is structured around three primary ethical dimensions:
    • Animal Welfare Ethics: Ensuring the physical and psychological well-being of the horse during and after the procedure.
    • Professional Ethics: Maintaining integrity, transparency, and competency in veterinary practice.
    • Procedural Ethics: Adherence to proper procedural protocols, safety measures, and minimizing risks.
  • Development involved an iterative process with 14 experts in both OPU procedures and applied ethics, ensuring practical applicability and ethical rigor.

Objectives and Benefits of the Checklist

  • Risk Reduction: Helps identify and mitigate procedural risks to both animals and staff.
  • Protection of Animal Welfare: Promotes practices that prevent unnecessary suffering or harm to horses.
  • Self-Assessment Approach: Empowers veterinary professionals to reflect critically on their practice, encouraging continuous ethical improvement.
  • Identification of Overlooked Issues: Enables detection of ethical concerns that might not be apparent in day-to-day routines.
  • Standardization: Provides a consistent framework for ethical monitoring of OPU procedures across different veterinary practices.
  • Transparency and Accountability: Fosters professional accountability and builds trust with clients and regulatory bodies.

Conclusion

  • The paper argues that integrating such an ethical checklist into daily veterinary practice enhances the responsible use of ARTs like OPU-ICSI.
  • By adopting this standardized self-assessment tool, veterinary practitioners can ensure that horse reproduction technologies are applied in an ethically sound and socially responsible manner.
  • This framework can potentially be adapted to monitor other emerging assisted reproductive procedures in veterinary medicine.
