Viscoelastic Properties of Zona Pellucida of Oocytes Characterized by Transient Electrical Impedance Spectroscopy [PDF]
Biosensors, 2023 The success rate in vitro fertilization is significantly linked to the quality of the oocytes. The oocyte’s membrane is encapsulated by a shell of gelatinous extracellular matrix, called zona pellucida, which undergoes dynamic changes throughout the ...

Female fertility and the zona pellucida [PDF]
eLife, 2022 Fertility in female mammals, including mice and humans, is dependent on the presence of a zona pellucida (ZP) around growing oocytes and unfertilized eggs.

Oviductin sets the species-specificity of the mammalian zona pellucida [PDF]
eLifeThe zona pellucida (ZP) is vital for species-specific fertilization as this barrier mediates sperm-oocyte binding. Here, we determined whether sperm from distant mammalian orders (Carnivora, Primates, and Rodentia) could penetrate bovine oocytes by ...

ZP1-Y262C mutation causes abnormal zona pellucida formation and female infertility in humans [PDF]
Frontiers in GeneticsDefective oocyte maturation is a common cause of female infertility. The loss of the zona pellucida (ZP) represents a specific condition of impaired oocyte maturation.

Effect of folicular fluid on the capacity of binding to the zona pellucida of epididimary sperm of alpaca (Vicugna pacos) [PDF]
SPERMOVA, 2017 Follicular fluid is the liquid fraction that surrounds the oocyte during its growth and maturation in the ovary. The components of the follicular fluid can favor the functionality of the sperm.

Fractal analysis of zona pellucida thickness: bending energy as a predictive window on day 2 embryo fate [PDF]
International Journal of Medical Device and Adjuvant Treatments, 2021 OBJECTIVE: The quality of the embryo is crucial for the outcome of in vitro fertilization; however, the ability to accurately distinguish embryos with the highest reproductive potential from others is not entirely reliable.
