Addition of Cryoprotectant DMSO Reduces Damage to Spermatozoa of Yellow Catfish (Pelteobagrus fulvidraco) during Cryopreservation: Ultrastructural Damage, Oxidative Damage and DNA Damage [PDF]
AnimalsSpermatozoa cryopreservation protocols have been established for yellow catfish (Pelteobagrus fulvidraco), but cryopreservation can still cause cellular damage and affect spermatozoa viability and fertility.

ANALYSIS OF SPERMATOZOA QUALITY USING PERCOLL DENSITY GRADIENT CENTRIFUGATION THROUGH THE ADMINISTRATION OF PHOSPHOLIPID + EGTA [PDF]
Journal of Applied Life Sciences and Environment, 2022 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.

Frontiers in Endocrinology, 2023 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]
Sci Data 10, 260 (2023), 2022 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
Fertility & Reproduction, 2023 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]
Acta Veterinaria, 2013 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.
