In March 2006, the Israeli Prison Service approved Amir's petition for in vitro fertilisation. The service was to study how this process would be conducted without Amir leaving the prison. A week later, Amir was caught handing a pre-prepared bag of semen to his wife, and the visit was terminated. After the incident, a disciplinary tribunal barred visits from his wife for 30 days, and phone calls for 14 days. He was fined NIS 100 (then US$21). When the IVF treatments were withheld due to a petition by several members of Knesset, Amir went on hunger strike. After being warned that hunger strikes are in violation of prison regulations, some of his privileges were cancelled.
