The allegations come just two days before jurors in Guzmán’s drug-trafficking trial in New York are set to begin deliberations.
Longtime associate Alex Cifuentes told authorities a woman would send Guzman photos of young girls to choose from, with a fee of USD 5,000 per girl.
Alex Cifuentes, who says he was a close associate of Guzman for years, told a New York City court that he had told authorities of the bribe in 2016, the BBC reported.
Prosecutors revealed that the 61-year-old drug lord used to plot crime deals with wife and lover via messages.
Jesus Zambada, a government informant held in US custody since 2008, said the bribes were delivered in person to Genaro Garcia Luna, Mexico's former public security minister, in 2005-2006.
