The role of spermatozoa-zona pellucida interaction in selecting fertilization-competent spermatozoa in humans [PDF]
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 ...

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.
