ANALYSIS OF SPERMATOZOA QUALITY USING PERCOLL DENSITY GRADIENT CENTRIFUGATION THROUGH THE ADMINISTRATION OF PHOSPHOLIPID + EGTA [PDF]

open access: yesJournal 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.

The role of spermatozoa-zona pellucida interaction in selecting fertilization-competent spermatozoa in humans

open access: yesFrontiers 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 ...

#338 : Insights into the Zona-Pellucida Mediated Selection of Fertilization-Competent Spermatozoa

open access: yesFertility & 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

Clinical benefits of a modified Cryopiece system for cryopreservation of rare ejaculated and testicular spermatozoa for ICSI

open access: yesAsian Journal of Andrology, 2022
Cryopreservation of rare testicular-retrieved spermatozoa for intracytoplasmic sperm injection (ICSI) in patients with severe oligozoospermia and azoospermia remains a major challenge in clinical practice.
