Markers of Oocyte Quality to Enhance Human IVF Outcomes: A Bibliographic Review

The markers of oocyte quality have remained a major controversy in the field of embryology due to the subjectivity of the different methods of oocyte assessment. Various scholars use oocyte quality and oocyte competence interchangeably. Oocyte quality can be defined as the overall health of an oocyte whereas oocyte competence refers to the ability of an oocyte to be fertilized and develop into a healthy embryo. Diminished oocyte quality is believed to be a result of alterations in oocyte growth and maturation processes that stem from several pelvic and systemic factors before and after oocyte retrieval. In this review, we focus on the morphological and nonmorphological markers of oocyte quality. Strict restrictions that limit the number of oocytes fertilized in various countries have triggered researchers around the world to come up with the most appropriate and noninvasive markers that enhance oocyte selection and optimize IVF outcomes. PubMed, Google Scholar, and the Cochrane Library were used to search for peer-reviewed, original articles about oocyte quality markers. The review was written in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Morphological markers are commonly used, but they are subjective, and no single marker can be used exclusively to predict oocyte competence and subsequent embryonic development potential. Furthermore, transcriptomics of differentially expressed genes in cumulus cells and assessment of metabolomics and other contents of follicular fluid have shown greater precision. However, their specificity to the different quality determinants needs further research.

外在小巧,内在丰盈。一间博物馆的内部空间必须广阔。一间博物馆的内部空间必须明亮。华茂艺术教育博物馆是一间体量小而内部宽广的博物馆。它倚靠小山坡,以波浪状的起伏姿态立于地面之上,以其优雅而迷人的特征吸引着人们。在这座小建筑之中,任何东西都是举重若轻。环绕建筑外延探索至内嵌于低矮屋檐下的公共入口,推开不起眼的大门将进入一个广阔的空间,挑高的建筑映入眼帘,沿蜿蜒的斜坡能到达不同楼层。这种介于"压缩"与"释放"之间的空间体验恒定地存在于参访的过程之中。多样化的参观流线以及相互连接的空间让这座小建筑的内部看起来开阔宽敞。
