The physiological aerobic bacterial flora of the low male genital tract was determined. This prospective study was performed on 600 semen specimens collected from 543 asymptomatic males consulting for infertility. Semen cultures were sterile in 28.8%, with a polymicrobial flora and/or absence or low titres of Ureaplasma urealyticum in 49.3%, and with one or two aerobic and facultative bacteria >= 1 x 10(3) CFU ml(-1) and/or U. urealyticum with titres >= 10(4) CCU ml(-1) (colour changing units) in 21.8%. In standard aerobic cultures, Gardnerella vaginalis was the most commonly isolated species (26.1%), followed by coagulase-negative staphylococci (15.7%) and Streptococcus anginosus (14.2%). Ureaplasma urealyticum was absent in 84.5% of semen samples, but when recovered, high (>= 10(4) CCU ml(-1)) and low titres (<= 10(3) CCU ml(-1)) were counted in 7.2% and 8.3% respectively. Of 48 patients, the follow-up of semen cultures showed marked variations in time. This study shows that (i) there was no relationship between the bacterial flora and the leucocytospermia; (ii) low titres of U. urealyticum in semen were not associated with a disturbance of the ecosystem; (iii) the critical threshold for U. urealyticum should be raised to >= 10(4) CFU ml(-1) and (iv) a positive semen culture should be repeated before any treatment.
