Abstract

A biomarker of unprotected receptive anal intercourse could improve validity of sexual behavior measurement. We quantified prostate-specific antigen (PSA) from rectal swabs from men who have sex with men (MSM). One swab was PSA positive. Using current methods, PSA is an inadequate biomarker of recent unprotected receptive anal intercourse in men who have sex with men.
