In 2019-2022 we enrolled men who have sex with men who did not engage in receptive anal sex but had other anorectal exposures (e.g., rimming). Of 29 men who tested positive for rectal chlamydia by nucleic acid amplification testing, only 10 (34.5%) were viable by culture or viability PCR.
Khosropour et al. (Thu,) studied this question.
