Donor–recipient sex mismatch in kidney transplantation may influence graft function recovery (GFR) and survival, particularly through sex-specific immune mechanisms. This issue is especially crucial in insular territories where access to transplantation is limited.
We conducted a single-center retrospective study at the University Hospital of Guadeloupe (2014–2024), including 335 kidney transplant recipients. Patients were stratified according to donor–recipient sex pairing: MM (male → male), FF (female → female), MF(male → female), and FM (female → male). The primary endpoint was graft function recovery (GFR), while the secondary endpoint was functional graft survival. Statistical analyses included mixed-effects models, Kaplan–Meier estimates, and Cox regression.
The FF group (female → female) achieved the most favorable outcomes: rapid recovery, no return to dialysis, and 100% three-year survival. Conversely, the MF group (male→ female) exhibited the least favorable outcomes, with 11% returning to dialysis and a reduced survival rate (69%). Donor age remained the strongest predictor of impaired recovery, whereas sex mismatch was not an independent factor in multivariate analysis.
Male-to-female mismatch was associated with delayed recovery and reduced graft survival, although not independently after adjustment. Integrating sex matching into allocation strategies could improve transplantation outcomes in resource-limited regions such as the French overseas departments and territories.
