The Ticking Clock: Differential Time‐Dependent Deterioration Between Washed and Thawed Sperm

Andrology, EarlyView.
ABSTRACT Background Cryopreservation is widely used in assisted reproductive technologies. While fresh sperm undergoes gradual time‐dependent deterioration, it remains unclear whether thawed sperm exhibits a more accelerated decline. Objectives To directly compare the rate of deterioration in sperm motility, vitality, and DNA fragmentation between ...

Pig Seminal Plasma Extracellular Vesicles Enhance Motility During Preservation of Epididymal Spermatozoa but Impair Capacitation and IVF Parameters

Andrology, EarlyView.
ABSTRACT Background Extracellular vesicles (EVs) produced by accessory sex glands play a key role in sperm functionality, influencing motility, viability, acrosome integrity, metabolic activity, and capacitation. Most studies on the effects of EVs on spermatozoa have focused on ejaculated spermatozoa, which have already been exposed to their own native

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

Andrology, 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
