assessment on the adverse effects of aminoglycosides and flouroquinolone on sperm parameters and male reproductive tissue: a systematic review

background: antibiotic therapies used in treatment of many diseases have adverse effects on fertility. this review analyzes previous comparative studies that surveyed the effects of two common groups of antibiotics on male fertility. objective: to evaluate histo-pathological effects of fluoroquinolones and aminoglycosides on sperm parameters and male reproductive tissue. materials and methods: articles about the effects of aminoglycosides and fluoroquinolones on male infertility, sperm parameters, male reproductive tissue, and spermatogenesis in english and persian languages published on google scholar and pubmed databases from january 2000 to december 2013 were assessed. randomized controlled trials (rcts) assessing the effects of aminoglycosides or fluoroquinolones on sperm parameters, artificial insemination, and male reproductive tract or rcts comparing aminoglycosides vs. fluoroquinolones were eligible for inclusion. for ascertaining the reliability of study, data were extracted independently and in duplicate by two investigators. results: sperm viability was decreased significantly with streptomycin, gentamicin, and neomycin (p<0.001). sperm motility was decreased significantly with gentamicin and neomycin (p<0.05). total sperm count was significantly decreased with ofloxacin, gentamicin, streptomycin, and neomycin (p<0.022). there was significant decrease in post-thawing motility with low dose and high dose of ciprofloxacin. testis weight was decreased with gentamicin and ofloxacin significantly (p<0.011). there was significant decrease in seminal vesicle weight with gentamicin, neomycin, and ofloxacin (p<0.022). furthermore, changes in epididymis weight, percentage of total apoptotic cells, and diameter of seminiferous tubule were significant with all drugs including streptomycin, gentamicin, neomycin, and ofloxacin (p<0.05). conclusion: streptomycin has less negative effects on cell’s apoptosis and sperm parameters as compared to other drugs. gentamicin has more detrimental effects so lesser dosage and duration is recommended. fluoroquinolones showed negative effects on testis tissue and sperm parameters. ciprofloxacin has less adverse effects than gentamicin in artificial insemination.
