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

The threshold of estradiol level for fresh embryo transfer differs between blastocyst and cleavage‐stage embryo

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Our results suggested that the difference in pregnancy outcomes between fresh and frozen embryo transfer is related to the peak estradiol level and embryo transfer stage. The cutoff values for peak estradiol level for performing freeze‐all strategy to improve pregnancy outcomes were different for cleavage‐stage and blastocyst‐stage embryo transfer ...
