Abstract:  Introduction:  Strong challenges exist about living kidney transplantation practices worldwide. One of these concerns is based on the observation that in many places women constitute the majority of living kidney donors but the minority of recipients. We studied this issue in Iran by using national data for kidney transplantation. Methods:  Data of the Iranian national registry for kidney transplantation which comprises data of all renal transplantations performed in the country during a 22 yr period were included in the study. Data of 16 672 living donors (living related [LR] = 16%, living unrelated [LUR] = 86%) were analyzed. Results:  Males received 62.2% of all kidney transplants. From 16 672 living donors, 20% and 80% were women and men, respectively. Recipients were more likely to receive kidney allograft from their own gender groups (p < 0.05). In living related donations, mothers, brothers and sons were significantly more often donors than their counterparts of opposite gender. Conclusion:  In contrast with previous reports from other countries, this study of Iranian national data revealed that in Iran, most related and unrelated living kidney donors are male and the percentage of recipients who are female exceeds the percentage of donors who are female. Considering previous reports from other countries, our findings suggest that Iran is the only country in which females are more likely to be recipients of a kidney allograft than donors. The reason for the predominance of male kidney donors in Iran is probably multifactorial and associated with economical, social and cultural issues. The financial incentives paid to living unrelated donors may be an attraction for males to donate a kidney although, even in living related donations, males constitute the majority of donors.
