Seminal Plasma Exosomal miRNA Profiling Reveals hsa‐miR‐7‐5p as a Key Regulator of Sperm Motility in Asthenozoospermia

open access: yesAndrology, EarlyView.
ABSTRACT Background Asthenozoospermia is a significant contributing factor to male infertility. Accumulating evidence indicates that impaired sperm motility is closely linked to dysregulated microRNA expression during spermatogenesis. Seminal plasma exosomes are enriched with diverse microRNAs, which play pivotal roles in modulating sperm motility, the
