Zona pellucida birefringence score and meiotic spindle visualization in relation to embryo development and ICSI outcomes.
The meiotic spindle and the zona pellucida exhibit molecular order when imaged with polarized optics. This study aimed to investigate possible factors contributing to the zona pellucida birefringence score and meiotic spindle visualization, and to evaluate whether these structures may predict intracytoplasmic sperm injection outcomes. Oocytes were divided into groups according to zona pellucida...
متن کاملO-11: Zona Pellucida Birefringence and Meiotic Spindle Visualization of Human Oocytes Are Not Influenced by In Vitro Maturation Technology
Background: In vitro maturation (IVM) is a promising treatment option for certain infertile women. Nowadays, with the aid of the Polscope, it has become possible to evaluate zona pellucida (ZP) and spindle as parameters of oocyte quality. The goal was to investigate the relationship between the presence of the meiotic spindle and ZP birefringence with morphology of the in vivo and in vitro matu...
متن کاملP-120: Meiotic Spindle Visualization and Zona Pellucida Birefringence in Relation to Morphology of In Vivo and In Vitro Matured Human Oocytes of In Vivo and In Vitro Matured Human Oocytesof In Vivo and In Vitro Matured Human Oocytes
Background: The meiotic spindle plays an important role in the oocyte during chromosome alignment and separation at meiosis. The zona pellucid (ZP) is a dynamic matrix composed of filaments with the properties that might reflect the history of oocyte cytoplasmic maturation. Since, spindle and ZP in living oocytes are highly birefringent, their structures can be viewed noninvasively by using a P...
متن کاملP-103: Polscope Analysis of Meiotic Spindle and Zona Pellucida Birefringence of Metaphase II Oocytes in Polycystic Ovarian Syndrome Patients
Background Polycystic ovarian syndrome (PCOs) is one of the most common causes of infertility in women of reproductive age. Currently, one of the best therapeutic options for PCOs patients is ICSI. Moreover, IVM can be a useful technique for women with PCOs who are at the risk of ovarian hyperstimulation syndrome (OHSS). On the other hand, the oocyte quality can be a determining factor for outc...
متن کاملRelationship between visualization of meiotic spindle in human oocytes and ICSI outcomes: a meta-analysis.
The objective of this meta-analysis was to investigate the influence of meiotic spindle visualization in human oocytes on intracytoplasmic sperm injection (ICSI) outcomes. Search strategies included on-line surveys of databases (MEDLINE, EMBASE, Science Citation Index, Cochrane Controlled Trials Register and Ovid). The fixed effect was used for odds ratio. Ten trials fulfilled the inclusion cri...
