Objective:To detect DNA of different microorganisms,in semen samples from apparently healthy men and correlate their presence with seminal quality.Methods:Semensamples from 81 healthy volunteers were collected,and semen parameters were analyzed.DNA extraction was performed using the phenol-chloroform technique,and the micro-organisms were detected by the amplification of specific primers using polymerase chain reaction.Results:DNA from at least one of the microorganisms was detected in 78 samples.The most frequent microorganism found in semen were:Lactobacillus spp.(70%),Neisseria gonorrhoeae(N.gonorrhoeae)(36%),Streptococcus epidermidis(64%),Klebsiella pneumoniae(56%),Staphylococcus aureus(32%),Chlamydia trachomatis(C.trachomatis)(28%),Pseudomonas aeru-ginosa(27%).The seminal parameters of all semen samples were over the lower reference values fornormal semenanalysis.To compare with negative samples,seminal volume was higher for the Escherichia coli positive samples and lower for Pseudomonas aeruginosa positive samples.Semen samples positive for Staphylococcus aureus had worse sperm morphology.The frequency of progressive motility was higher in positive samples for N.gonorrhoeae and C.trachomatis.Positive semen samples for C.trachomatis had a higher concentration per milliliter.Conclusion:It is common to find microorganisms in semen of asymptomatic men,including those responsible for sexually transmitted infections.Antimicrobial treatment is recommended only in those individuals with a sexually transmitted infection(C.trachomatis and N.gonorrhoeae)and always promote condom use.
