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

Sperm Sexing in Selected Animals and Humans: Methods, Applications, and Future Prospects

Andrology, EarlyView.
ABSTRACT Background Sperm sexing is a technique that enables the selection of offspring sex by sorting spermatozoa based on their sex chromosomes. This technology has gained increasing attention due to its potential applications in both animal breeding and human‐assisted reproduction.

Impact of Sorting and Catch Media on Porcine Sperm Motility, Capacitation, and Viability

Andrology, EarlyView.
ABSTRACT Background Fluorescence‐activated cell sorting (FACS) has emerged as a powerful tool for selecting spermatozoa of a desired population of fluorescent biomarkers, offering potential applications in reproductive biology and agriculture. However, concerns remain regarding sorting‐induced physiological alterations that could compromise spermatozoa

Microfluidic Intracytoplasmic Sperm Injection (MICSI): A Novel Platform for Sperm Isolation, Selection, and Injection Into Oocytes

Andrology, EarlyView.
ABSTRACT Background Infertility is a pressing global health concern, affecting one in six couples worldwide. The failure rate for assisted reproductive technologies (ART) cycles remains at approximately 78%, with limited improvements often attributed to a lack of technological innovation.
