Abstract Study question Does follicular fluid (FF) exposure shape human sperm RNA content and are these changes acquired through genomic or nongenomic manner? Summary answer FF altered potentially via activation of transcription machinery caused selective intake transcripts in sperm. What is known already Mature have been widely recognized as transcriptionally inert. Therefore, RNAs regarded th...

varicocele is one of the most common causes of primary male infertility. pilea microphylla (pm) is being used as folk medicine. this study was aimed to investigate the effects of pm in a rat model of varicocele. a total of 30 male wistar rats were divided into control, sham, varicocele, accessory varicocele and pm-treated groups. after 10 weeks of varicocele induction, sperm parameters and chro...

conclusions: saffron, as an antioxidant, is positively effective on sperm parameters in rats exposed with cadmium. objectives: the aim of this study was to determine the effects of saffron on the results of semen parameters (sperm concentration, motility and viability in cauda of epididymis) in rats exposed to cadmium. materials and methods: thirty wistar male rats were divided into four groups...

background: male are involved in near 50% of cases of infertility and reactive oxygen species (ros) playing an important role in decreasing fertility potential. accurate measurement of ros seems to be important in evaluation of infertile male patients. objective: to compare ros measurement in neat and washed semen samples of infertile men and define the best method for evaluation of ros in thes...

The effect on sperm motility of sperm-sperm and sperm-seminal plasma interactions was studied among homologous and heterologous sperm. There were no significant interactions between sperm in vitro, but it was found that seminal plasmas of different donors have different effects on sperm motility, and different sperm react differently to the same seminal plasma. Sperm showed higher motility in a...
