Over the last years, efforts by transplant professionals and transplant organizations have resulted in the strengthening of laws and sentences against virtually all forms of organ trade (1-4). The prevailing belief is that organ trade can be prevented by countries becoming "self-sufficient" (4, 5). Iran is the only country that reports to have eliminated its kidney transplant wait list (6, 7). Yet, it is largely condemned for having accomplished this by paying living kidney donors (8-10). Transplant professionals from Iran state that they are often prevented from presenting data about the Iranian model at international transplant conferences and in transplant journals. Furthermore, the regulations that underlie Iran's decentralized, semi-regulated organ payment programs, differ between the country's states, leading to differing outcomes (11)(12)(13)(14). These cross-country variations, in conjunction with the limited available data, hampers an in-depth understanding of the Iranian model (10,15,16). 1 Moeindarbari's and Feizi's study contributes to vital knowledge gaps in this regard. Drawing on a unique data-set collected from the Kidney Foundation in Mashhad, Moeindarbari and Feizi present an analysis of price arrangements between 436 donors and recipients. The findings illustrate, amongst other things, the effects of education, gender, age difference and donor-recipient relationships on kidney prices. In addition, the findings suggest that related donors sell their kidneys to close relatives for a significantly lower price. Government payments are additionally made under the scrutiny of the Ministry of Health for all transplant-related expenses. The authors further explain that donors are provided with medical coverage for 1 year after the nephrectomy and that they are exempted from military service (6).There are however some concerns about the Iranian model. Mashhad's kidney transplant program tolerates side payments between recipients and donors besides the fixed government fee. This is problematic because prices fluctuate according to the bargaining skills and abilities of donors and recipients. These unregulated transactions in turn may cause and exacerbate a variety of issues including inequality and interpersonal exploitation. Furthermore, while donors are provided with medical coverage for 1-year post-donation, it is unclear whether life-long follow up is guaranteed.
