Recently discovered microcolonial forms of Mycoplasma hominis(***)and their impact on human spermatogenesis are *** spermatozoa of 125 fertile men(sperm donors;from Reprobank[Reproductive Tissue Bank,Moscow,Russial)and of 93 patients with fertility problems(from the Federal State Budgetary Institution"Research Centre for Medical Genetics[RCMG]",Moscow,Russia)were *** colonies of *** and microcolonies were detected by molecular biological methods,culture of bacteria,and transmission electron *** unique structure of microcolonial cells,in which the cytoplasmic cylinder is surrounded by concentric electron-dense and electron-light layers with a periodicity of 12-14 nm,and the ability of microcolonial cells to attach to spermatozoa are *** patients with lower sperm quality,microcolonies of *** were detected 2.5 times more frequently than classical *** detection of microcolonies in the ejaculate and the frequent isolation of microcolonies from sperm samples of patients with fertility problems suggest that microcolonial cells may be one cause of infertility.
