If transmen are seeking hysterectomies as part of their transition do they become a source of live donors? A lot are young and healthy women, so potentially good donors.
It's been suggested. Transgender Males as Potential Donors for Uterus Transplantation: A Survey
And also in the Imperial College paper from the surgeons who carried out this first female womb transplant (my bold):
Despite a number of anatomical, hormonal, fertility, and obstetric considerations that require consideration, there is no overwhelming clinical argument against performing UTx as part of GRS. However, the increased radicality associated with the retrieval operation, including a longer vaginal cuff and more extensive ligamentous dissection, potentially necessitates the use of deceased donors. Alternatively, F2M transgender men may offer an alternative donor pool should they accept the increased risk compared with standard hysterectomy. Prior to undertaking UTx in transgender women, further research should be undertaken including cadaveric retrieval and implantations to assess the feasibility of the anatomical considerations discussed herein.
