Context: The significant contribution of the male partner to infertility is no longer in doubt. There is however little disagreement regarding the frustrating experience with medical management of male infertility. The effect of infection as a contributor to abnormalities in semen parameters has been reviewed. Objectives: The study was aimed at identifying male factor contribution to infertility and the influence of bacterial infection on seminal parameters. Study-design, setting and subjects: All 202 patients were spouses of infertile women who presented to the Gynaecological clinic of the Federal Medical Centre Gombe over a one-year period, from January to December 2001 inclusive. Results: The density of spermatozoa ranged from 0-844x10 6 /ml with a mean of 44.588.5 x10 6 /ml. Only 94 (46.5%) of the patients had the reference lower limit normal density of 20 million spermatozoa/ml or more. However, 111 (55%) were normozoospermic for total count with 64 (31.7%) being oligozoospermic. There were bacterial isolates from the seminal fluid of 134 (66.3%) patients that was predominantly accounted for by S. aureus 67.2% (90/134). The seminal fluid produced was 1-8mls, with a mean of 3.11.7mls of which 45 (22.3%) were oligospermic. The mean pH was 7.10.3, in 16 (7.9%) patients the seminal fluid pH was 8-9.There were 27 (13.4%) azoospermic men, in 163 (80.7%) the spermatozoa had normal morphology of 70% or more while 12 (5.9%) men had abnormal morphology of 30% or more i.e. were teratozoospermic. All cases with no abnormal (or normal) morphology were actually azoospermic. There was a significant association between the presence of bacterial isolate in the seminal fluid and oligozoospermia. However the motility, morphology or the count do not seem to be affected by the presence of infection. Conclusion: Bacterial presence contribute significantly to poor semen quality in our environment. Primary prevention and prompt treatment of urogenital infections could reduce the infectious contribution to male infertility.
