"I, Vahid Vakilifar, an independent filmmaker, 43 years old, blood type B negative, have decided to sell one of my kidneys due to my financial situation. Please send your offers to the following email address," he wrote in an Instagram post on Tuesday.
Iranians are struggling with high prices, sanctions and a crippling exchange rate.
The news prompted the Independent Filmmakers Association of Iran to issue a statement criticising the Iranian government. They linked Vakilifar's act to the state's repressive policies and highlighted the dire financial conditions faced by independent artists in the country.
"(It's) a shocking and painful act against a filmmaker half of whose works remain unreleased," the Association said. "Cinema authorities in Iran...impose increasing restrictions rather than improving conditions for filmmakers."
The incident is not an isolated phenomenon. Reports of young Iranians, particularly those in their 20s, selling their organs to make ends meet have been on the rise.
According to a report by Iranian economic outlet Tejarat News in March, being a young donor is regarded as an advantage, with young sellers referring in the advertisements to their age and athleticism as their strong points.
