Surgical Approach, Challenges, and Resolutions for Uterus Transplantation in Rats

Area of Science:

• Reproductive Medicine
• Surgical Innovation
• Animal Models in Research

Background:

• Absolute uterine factor infertility (AUFI) affects 3-5% of women, previously leaving childbearing impossible.
• Uterine transplantation (UTx) has emerged as a novel treatment option for AUFI.
• Experimental UTx in animal models, particularly rats, has been crucial for clinical advancements.

Purpose of the Study:

• To present a detailed protocol for uterine transplantation (UTx) in a rat model.
• To provide essential troubleshooting guidance for rat UTx procedures.
• To facilitate the understanding and execution of rat UTx for researchers and surgeons.

Main Methods:

• Detailed surgical protocol for rat uterine transplantation.
• Microsurgical techniques adapted for small anatomical structures.
• Experimental design focused on achieving successful pregnancy and live birth as endpoints.

Main Results:

• Successful UTx in rats, demonstrating the feasibility of the procedure.
• Identification of key challenges, including the requirement for advanced microsurgical skills.
• Establishment of a reproducible experimental model for UTx research.

Conclusions:

• Rat models are suitable for UTx research due to shared physiological characteristics and short gestation periods.
• The presented protocol and troubleshooting aim to simplify rat UTx, aiding further research and clinical translation.
• Continued experimental optimization is necessary to establish UTx as a standard clinical procedure for AUFI.
