The cause of asthenozoospermia(AZS)is not well understood because of its complexity and heterogeneity.Although some gene mutations have been identified as contributing factors,they are only responsible for a small num...
Male infertility is a global issue caused by poor sperm quality,particularly motility.Enhancement of the sperm quality may improve the fertilization rate in assisted reproductive technology(ART)treatment.Scriptaid,wit...

The process of semen collection plays a key role in the quality of semen specimens.However,the association between semen collection time and semen quality is still unclear.In this study,ejaculates by masturbation from...
Objective:The relationship between mitochondrial DNA(mtDNA)polymorphisms and abnormalities in sperm quality has been the subject of several studies,with the objective of improving the treatment of male infertility.Thi...

Asthenozoospermia is the most common cause of male infertility.Dynein protein arms play a crucial role in the motility of both the cilia and flagella,and defects in these proteins generally impair the axoneme structur...
Spermatozoa contain a repertoire of RNAs considered to be potential functional fertility biomarkers.In this study,the gene expression of human sperm subpopulations with high(F1)and low(F2)motility from healthy normozo...
