U.S., Feb. 22 -- ClinicalTrials.gov registry received information related to the study (NCT06839495) titled 'To Investigate the Relationship Between the Viscoelastic Properties of the Zona Pellucida of Human Oocyte and the Blastocyst Utilization Rate' on Feb. 13.
Brief Summary: In in vitro fertilization (IVF) treatment, oocyte quality is one of the key factors influencing the success rate of fertilization. The zona pellucida (ZP) is a spherical structure that surrounds the human oocyte and, together with cumulus cells, forms the cumulus-oocyte complex (COC). These two components engage in bidirectional communication and metabolic regulation to support oocyte growth and maturation. Additionally, the physical rigidity of the zona pellucida p...
