RESUMEN
Objective: To compare semen analysis parameters between bacteriospermia and non-bacteriospermia specimens in men attending at infertile clinic.Methods: A total of one hundred men who attending an infertility clinic between 1st September 2006 -31st January 2007 at Thammasat hospital was enrolled into the study. After soap and water skin preparation, all men gave semen specimens for culture and semen analysis by Computer-Assisted Sperm Analysis (CASA). The main outcome measures were presence or absence of bacteriospermia, the specific bacterial isolate and semen analysis parameters.Results: The incidence of bacteriospermia was 14%. Staphylococcus species were the most common organisms following by Streptococcus species, Escherichia coli, Proteus mirabilis and Pseudomonas aeruginosa, respectively. There was no significant difference in semen analysis parameters especially leukocytospermia between bacteriospermia and non-bacteriospermia specimens (P \> 0.05).Conclusions: Bacteriospermia does not impact to semen analysis parameters especially leukocytospermia.
