Daily subcutaneous doses of 0.02, 0.2, or 2 mg/kg/d of recombinant murine interferon-gamma (rmuIFN-gamma) were given to mice on postnatal days 8 through 60 to determine effects on maturation, behavioral/ functional development, and reproductive capacity. Male mice receiving 2 mg/kg/d rmuIFN-gamma had delayed sexual maturation, reduced epididymal and testes weights, reduced sperm count and concentration, and sperm abnormalities (crimped flagellum). Mating performance and fertility were also reduced in the absence of altered histopathology of the testes. Males given 0.2 and 2 mg/kg/d had swelling and ulcerative dermatitis around the urogenital area, which were observed after sexual contact and attributed to a bacterial infection. Motor activity (time spent in movement) was decreased in all mice receiving 2 mg/kg/d. No microscopic changes observed in any organs were attributed to rmuIFN-gamma administration.

Sexually transmitted diseases (STDs) affect the physiology of male/female reproduction. Chronic bacterial infection of semen is uncommon, but may be a cause of male infertility. Antibacterial treatment results in improvement in sperm quality, once the infection is eradicated. Little is known about how infection with Mycoplasma hominis affects semen quality, but treatment with antibiotics improves motility and decreases the percentage of coiled tails. Chlamydia trachomatis is not frequently isolated from the urethral cultures of normal men, but is a major cause of nongonococcal urethritis and epididymitis. Chlamydia is an important cause of epididymal and oviductal obstruction. Trichomonas vaginalis most frequently colonizes the vagina and cervix of women and the anterior urethra of the male sexual partners. The highest prevalence is in sexually active men and women and Trichomoniasis may well be the most common STD. Syphilis may be an important cofactor in facilitating transmission of the human immunodeficiency virus (HIV). A history of syphilis or a positive serologic test for syphilis is associated with HIV seropositivity in men. In South Africa, the seropositivity in pregnant black women ranges from 11-20%. Ga-Rankuwa Hospital is the referral center for 40 peripheral hospitals and over 4 million people. Since the inception of the Andrology Laboratory in June 1985, more than 5300 semen analyses have been performed on 2000 patients.

Epididymitis represents a serious threat to male fertility and usually develops following secondary bacterial infection of the epididymis such as urinary tract infections or sexually transmitted diseases. Surprisingly, very little is known about the innate host response triggered by bacterial infection in the male reproductive tract. In this study we investigated the regulation and function of Nod2 in epididymal epithelial cells following lipopolysaccharide (LPS) stimulation. The immortalized epididymal epithelial cell line PC1 (proximal caput 1) constitutively expressed Toll-like receptor 4, MD-2, CD-14 but not Nod2 messenger RNA. Lipopolysaccharide (LPS; 0.5 microg/ml) rapidly induced I kappaB phosphorylation and degradation, RelA nuclear translocation and phosphorylation, which correlated with enhanced transcriptional activity (four-fold) in PC1 cells. The LPS and lipid A rapidly (1 hr) induced Nod2 messenger RNA accumulation in a dose-dependent manner. RelA and RNApolII recruitment to the Nod2 gene promoter was enhanced in LPS-stimulated cells. Molecular blockade of nuclear factor-kappaB signalling with adenovirus 5 (Ad5) I kappaB AA or adenovirus 5 double-negative (Ad5dn) IKK beta prevented LPS-induced Nod2 gene expression. Functionally, Nod2 upregulation enhanced muramyl dipeptide (MDP) -induced tumour necrosis factor messenger RNA accumulation in PC1 cells. We conclude that epididymal epithelial cells mount an innate response following LPS exposure which leads to upregulation of Nod2 and enhanced responsiveness to the microbial product MDP. The rapid Nod2 upregulation in epididymal epithelial cells is probably part of a complex innate host response aimed at protecting the male reproductive tract from the deleterious impact of bacteria.

Background. The role of adipose tissue in systemic inflammation during bacterial infection is unclear. Effects of Staphylococcus aureus infection on adipocytes in rodent models of experimental endocarditis and peritonitis, the impact of S. aureus infection on gene expression in epididymal and subcutaneous adipose tissue, and effects of S. aureus infection on the toll-like receptor-2- (TLR2-) cathelicidin pathway in vivo and in vitro were investigated. Material and methods. The rat model of catheter-induced S. aureus endocarditis and the mouse model of S. aureus-induced peritonitis were used for infection experiments, gene expression profiling in adipose tissue, and measurement of cytokines. 3T3-L1 adipocytes were analyzed for expression of the TLR2-cathelicidin pathway. Results. Upon systemic bacterial infection by S. aureus, there is a shift from anti- to proinflammatory cytokines in serum and in adipose tissue gene expression. The TLR2-cathelicidin pathway is increasingly expressed during adipocyte differentiation in vitro and is induced upon stimulation by synthetic lipopeptides. Conclusions. Systemic infection by Gram-positive bacteria induces proinflammatory transformation of adipose tissue sites distinct from infection sites, documented on the levels of gene expression and secreted mediators. The TLR2-cathelicidine pathway is expressed and highly inducible in adipocytes in vitro. Lipopeptides are important immune-modulators of adipocytes in both gene expression and protein secretion.

Acute epididymo-orchitis is an inflammatory process caused by bacterial infection. Emphysematous epididymitis is an extremely rare manifestation characterized by gas within the epididymal tissues. We report a case of emphysematous epididymitis following hydrocelectomy in a patient with a history of spinal cord injury and chronic bacteriuria. The diagnosis was made by clinical and laboratory data with imaging demonstrating foci of gas within the epididymal structures. We hypothesize that intermittent catheterization may have contributed to bacterial translocation into the adjacent cord structures and development of infection. High level of suspicion leading to early diagnosis, aggressive antibiotics and adequate debridement are required.
