Bacteriospermia, extended spectrum beta lactamase producing Gram-negative bacteria and other factors associated with male infertility in Mwanza, Tanzania: a need of diagnostic bacteriology for management of male infertility.

Background: Infections caused by Extended spectrum beta lactamase (ESBL) producing bacterial are global challenge. There is limited information on the magnitude of bacteriospermia, ESBL producing Gram-negative bacteria (GNB) causing bacteriospermia and factors associated with male infertility. This study determined magnitude of bacteriospermia, ESBL-GNB and other factors association with infertility among presumptive infertile men in Mwanza, Tanzania.
