Ultrastructural evidence for the activation of autophagy and analysis of the protective role of autophagy in goat spermatozoa under liquid storage [PDF]
Liquid storage of semen is a widely used technology for promoting genetic improvement in goat breeding. The short shelf life of spermatozoa greatly limits the application of liquid storage, which urgently needs to explore the underlying regulatory ...

ANALYSIS OF SPERMATOZOA QUALITY USING PERCOLL DENSITY GRADIENT CENTRIFUGATION THROUGH THE ADMINISTRATION OF PHOSPHOLIPID + EGTA [PDF]
The Percoll density gradient centrifugation (PDGC) method is frequently used in the sexing of spermatozoa. However, this method causes damage to the spermatozoa membranes, resulting in a decreased quality of spermatozoa.

Human fertilization begins when a capacitated spermatozoon binds to the zona pellucida (ZP) surrounding a mature oocyte. Defective spermatozoa-ZP interaction contributes to male infertility and is a leading cause of reduced fertilization rates in ...

VISEM-Tracking, a human spermatozoa tracking dataset [PDF]
A manual assessment of sperm motility requires microscopy observation, which is challenging due to the fast-moving spermatozoa in the field of view. To obtain correct results, manual evaluation requires extensive training. Therefore, computer-assisted sperm analysis (CASA) has become increasingly used in clinics.

#338 : Insights into the Zona-Pellucida Mediated Selection of Fertilization-Competent Spermatozoa
Background and Aims: Human zona pellucida (ZP) selectively interacts with high-quality spermatozoa characterized by superior morphology and normal chromatin structure to achieve fertilization. Human ejaculate contains millions of spermatozoa with varying

The relationship between seminal plasma aspartate aminotransferase activity, sperm osmotic resistance test value, and semen quality in boars [PDF]
The relationship between the activity of aspartate aminotransferase (AspAT) in seminal plasma and the values of the osmotic resistance test (ORT) of acrosomal membranes and semen traits was examined on 120 young hybrid Pietrain and Duroc boars.

Increased frequency of aneuploidy in long-lived spermatozoa. [PDF]
Aneuploidy commonly causes spontaneous abortions, stillbirths, and aneuploid births in humans. Notably, the majority of sex chromosome aneuploidies in live births have a paternal origin.
