Uterus transplant: evidence and ethics

Area of Science:

• Reproductive Medicine
• Transplantation Surgery

Background:

• Absolute uterine infertility impacts millions globally, with many women undergoing hysterectomies annually.
• Thousands of women who have had hysterectomies may be candidates for uterus transplantation.
• Potential recipients often have conditions like Rokitansky syndrome, endometriosis, or cervical cancer.

Purpose of the Study:

• To explore the feasibility and progress of uterus transplantation as a method for fertility restoration.
• To summarize the research and development leading to current uterus transplantation efforts.

Main Methods:

• Review of fertility preservation research, including radical trachelectomy and in situ uterus techniques.
• Analysis of a decade of modern animal research, including large animal allografts and nonhuman primate studies.
• Examination of early human uterus transplant attempts and ongoing clinical studies.

Main Results:

• Animal research has provided a foundation for human uterus transplantation.
• Nonhuman primate models are being used to further investigate the procedure.
• While the first human transplant in 2000 did not result in pregnancy, significant progress has been made.

Conclusions:

• Uterus transplantation, building on fertility preservation and extensive research, is progressing towards becoming a viable option.
• Ongoing global research is crucial for refining immunosuppression and surgical techniques.
• Uterus transplantation may soon offer a reality for women facing absolute uterine infertility.
