results among 100 samples from infertile males, the presence of genus mycoplasma was confirmed in 45 cases of which 15 cases were infected with m. hominis. among 100 samples from infertile female, the presence of genus mycoplasma was confirmed in 43 cases of which 18 case were infected with m. hominis. the positive samples were sequenced and the phylogenetic tree was plotted. conclusions the re...

introduction: the prevalence of somatic chromosomal abnormalities in infertile male individuals has been reported to vary in different literatures. the aim of this study was to investigate the frequency of chromosomal aberrations among infertile men referred to the cytogenetic laboratory of iran blood transfusion organization research centre (ibto). materials and methods: chromosomal analysis w...

context air pollution is common in all countries and affects reproductive functions in men and women. it particularly impacts sperm parameters in men. this meta-analysis aimed to examine the impact of air pollution on the quality of sperm. conclusions the results of this meta-analysis showed that air pollution reduces sperm motility, but has no impact on the other sperm parameters of spermogram...

background: the trace element copper has been identified as a highly toxic element for sperm. it is known to affect sperm motility in humans and experimental implantation of copper in the epididymis vas deferens and scrotum of mammals has been demonstrated to affect fertility detrimentally. objective: sperm concentration motility vitality and morphology are parameters used to evaluate potential...

studies represent that bacterial infection of the semen can have a direct role in spermatozoid parameters change and may result in men's infertility. in the present study 160 semens were examines for bacterial infection. 55(34.4%) were infected by different species of bacteria, but those infected only by 4 species were undertaken for further study.these bacteria were streptococci pyogen, entroc...

background: oxidative stress is detrimental to semen quality and has a significant role in the etiology of male subfertility. methods: dietary intake of antioxidants were compared between thirty two men with oligolastheno/ teratazoospermic (cases) and 32 normospermic volunteers (controls) attending fertility clinic in mirza koochak-khan hospital in tehran, iran. all participants were nonsmokers...

a key factor in spermatogenesis and disorders associated with this protein have been recognized to be related to male infertility. although it was suggested that this protein could have different functions during germ cell development, no studies have been conducted to uncover the mechanism of this potential function yet. here, we analyzed the expression pattern of rbmy protein isoforms in test...

background: ubiquitin, an 8.5 kda peptide that marks other proteins for proteasomal degradation, tags defective sperm dur­ing epididymal passage. thus, sperm ubiquitination is a universal marker for sperm defects and can be used as a sperm func­tion test. the objective of the present study was to examine the relationships between sperm ubiquiti­nation and clinical se­men parameters, using simpl...
