Abd al-Rahim Hussein Muhammad Abdah al-Nashiri, one of al-Qaeda's senior leaders held at Gitmo, took injections "to promote impotence" in order to avoid being "distracted" by women. His interrogators reported: "Detainee is so dedicated to jihad that he reportedly received injections to promote impotence and recommended the injections to others." He took the injections "so more time could be spent on jihad -- rather than being distracted by women".
Al-Nashiri was allegedly "the senior operative" in the USS Cole attack. He was also accused of planning the suicide attack that badly damaged the MV Limburg, a French oil tanker, in 2002. Al-Nashiri has been "linked to as many as a dozen plots to attack US and Western interests" and his cell "was responsible for conducting suicide and sabotage operations outside Afghanistan".
Captured in the United Arab Emirates in November 2002, Al-Nashiri was transferred to Gitmo in September 2006, suggesting that he spent a long time in the CIA secret prison network.
Al-Nashiri is one of only three detainees known to have been subjected to waterboarding. He has subsequently claimed that he made several false confessions under torture. He remains at Gitmo.
