Many previous studies have aimed at spermatogenesis of male murine germ cells in vitro, but no efficient system has been established yet that covers the entire process of mammalian spermatogenesis in a culture dish permanently. In this review, we report on the requirements of spermatogenesis and the current state of different culture methods using testicular tissue fragments, single cell suspen...

In eukaryotes, post-transcriptional regulation of gene expression has a key role in many cellular and developmental processes. Spermatogenesis involves a complex developmental program that includes changes in cell cycle dynamics and dramatic cellular remodeling. Translational control is critical for spermatogenesis in Drosophila as many mRNAs synthesized in the spermatocytes are translated only...

metronidazole and it’s derivatives are drugs that have both antiprotozoal and anti bacterial effect.the reproductive toxicity of metronidazole has been shown in some studies. to investigate the effect of metronidazole on spermatogenesis in adult male rats, this study was designed. eighteen wistar male rats (70-90days old) were randomly divided into three groups. animals in group i (control grou...
