Uterine transplantation: What else needs to be done before it can become a reality?

Uterus transplantation: Toward clinical application in Japan

Background

In recent years, uterus transplantation (UTx) has been applied as the treatment for patients with uterine factor infertility worldwide. Thus, the clinical application of UTx in Japan should be considered through both the history of UTx technology development in the world and future prospects.

Methods

Recent information on UTx was collected via a literature survey and the Internet.

Results

Basic research using various animals has been done mainly since 2000. In 2014, the world's first UTx baby was born in Sweden. In total, 24 UTx procedures have been performed at 10 institutes in nine countries and five births were obtained (as of May, 2017). In Japan, the "Project Team for Uterus Transplantation" initiated UTx experiments in 2008 and the "Japan Society for Uterus Transplantation" was organized in March, 2014. In the rest of the world, the "International Society for Uterus Transplantation" was established in January, 2016.

Conclusion

Uterus transplantation is still under development as a reproductive medicine tool and organ transplant procedure. A collaborative system that is not limited by facilities and specialties should strive to build an "all-Japan" team.

Survey of Perceptions of Health Care Professionals in the United Kingdom toward Uterine Transplant

Context

Currently, the only 2 options that women with absolute uterine factor infertility have for managing their infertility are surragocy or adoption. These women may also benefit from a possible future third option: uterine transplant

Objective

To investigate the opinions and views of UK health care professionals toward uterine transplant and rank issues related to uterine transplant by importance in order to make uterine transplant transparent and understandable to colleagues.

Design

Large, in-depth survey investigating health care professionals' opinions on uterine transplant.

Setting

Analysis done at Imperial College London.

Participants

UK transplant professionals (surgeons, nurses, operating room staff, and donor coordinators) and obstetricians and gynecologists (trainees, members, and fellows of the Royal College of Obstetricians and Gynaecologists).

Intervention

Questionnaires were given out at hospital grand rounds, trainee teaching days, and conferences (national and international).

Main Outcome Measures

Should uterine transplant take place? Is uterine transplant achievable? What is the rank order of importance of key issues related to uterine transplant?

Results

The study had 528 participants. With respect to overall support for uterine transplant and as a possible future therapeutic option for absolute uterine factor infertility, 93.8% (n=495) thought that uterine transplant should take place if considered appropriate medically, surgically, and ethically and 57.2% (n= 302) thought it was an achievable objective. Issues related to immunology of uterine transplant and pregnancy after uterine transplant were unanimously thought of as most important. More effort is required to educate health care professionals about all aspects of uterine transplant.
