Detection and identification of bacterial DNA in semen

Objective: To detect and identify bacteria in semen by sequencing polymerase chain reaction (PCR)–amplified ribosomal RNA gene regions (rDNAs). Design: BacterialrDNAsweredetectedbyPCRamplificationofsemenDNA.Conditionswereadjustedtodetect only abundant organisms, no fewer than 20,000 bacteria/mL of semen. Setting: Clinical andrology laboratory and academic research laboratories. Patient(s): Men undergoing fertility evaluation (n 1⁄4 29) or vasectomy (n 1⁄4 5).
