Asymptomatic bacteriospermia in fertile and infertile men.

Bacterial flora of the seminal fluid were examined in 430 asymptomatic men. Fertile men had significantly fewer positive cultures than any other group selected from the infertile population. Significantly more bacterial isolates were obtained from patients with a history of genital tract infection than from infertile men without a history of genital tract infection. Asymptomatic bacteriospermia was significantly more common among patients with a history of gonorrhea infection than in any other studied groups. Ureaplasma was isolated with the highest frequency from patients with nonspecific urethritis and/or with gonorrhea. It is proposed that follow-up seminal fluid cultures should be used to determine the end-point in treating male genital tract infections.
