The aerobic and anaerobic flora of the semen was examined in 109 men visiting our infertility clinic. Not one specimen was sterile and 107 specimens contained two or more different bacterial species. Anaerobic organisms were found in 63.3% of specimens. We were able to isolate various organisms that have been shown to be spermicidal in vitro (viridans and hemolytic streptococci, Proteus vulgaris and Escherichia coli) from a large number of samples. If the presence of microorganisms in the semen is associated with infertility, it is likely that only certain organisms are involved or that the numbers of organisms must be high for an effect to be seen. The presence of organisms in the semen may also be related to gynecologic infections.
对109名前来我们不孕不育诊所就诊的男性的精液需氧菌和厌氧菌菌群进行了检查。没有一份标本是无菌的，107份标本含有两种或更多不同的细菌种类。63.3%的标本中发现了厌氧菌。我们能够从大量样本中分离出各种已被证明在体外具有杀精作用的微生物（草绿色链球菌和溶血性链球菌、普通变形杆菌和大肠杆菌）。如果精液中微生物的存在与不孕有关，那么可能只有某些微生物参与其中，或者微生物数量必须很高才能产生影响。精液中微生物的存在也可能与妇科感染有关。
