Abstract

A significant problem associated with assisted reproductive technologies (ART) is recurrent treatment failure which can be attributed to the age-associated decline in oocyte quality. Co-enzyme Q10 (CoQ10) is an antioxidant and essential component of the mitochondrial electron transport chain. It is reported that de novo CoQ10 production declines with ageing and coincides with age-related decline in fertility, leading to CoQ10 supplementation being advocated to enhance response to ovarian stimulation and improve oocyte quality. CoQ10 supplementation was found to improve fertilization rates, embryo maturation rates and embryo quality when used before and during in vitro fertilization (IVF) and in vitro maturation (IVM) treatment in women aged 31 and over. Regarding oocyte quality, CoQ10 was able to reduce high rates of chromosomal abnormalities and oocyte fragmentation, as well as improve mitochondrial function. Proposed mechanisms of CoQ10 function include restoration of reactive oxygen species imbalance, preventing DNA damage and oocyte apoptosis, as well as restoration of Krebs cycle downregulation from ageing. In this literature review, we provide an overview of the use of CoQ10 in improving the success of IVF and IVM in older women, and additionally assess the impact of CoQ10 on oocyte quality and discuss potential mechanisms of action by CoQ10 on the oocyte.

补充辅酶Q10对老年妇女抗逆转录病毒疗法和卵母细胞质量的影响
辅助生殖技术(ART)的一个重要问题是反复出现治疗失败,这可能是由于年龄增长导致卵母细胞质量下降。辅酶 Q10(CoQ10)是一种抗氧化剂,也是线粒体电子传递链的重要组成部分。据报道,随着年龄的增长,辅酶Q10的新生成量会下降,并与年龄相关的生育能力下降相吻合,因此人们提倡补充辅酶Q10以增强对卵巢刺激的反应并改善卵母细胞质量。研究发现,在体外受精(IVF)和体外成熟(IVM)治疗前和治疗期间,31 岁及以上女性补充辅酶 Q10 可提高受精率、胚胎成熟率和胚胎质量。在卵母细胞质量方面,辅酶Q10能够降低染色体异常和卵母细胞破碎的高发率,并改善线粒体功能。CoQ10 的功能机制包括恢复活性氧失衡,防止 DNA 损伤和卵母细胞凋亡,以及恢复老化导致的克雷布斯循环失调。在这篇文献综述中,我们概述了使用辅酶Q10提高高龄女性试管婴儿和试管婴儿成功率的情况,此外还评估了辅酶Q10对卵母细胞质量的影响,并讨论了辅酶Q10对卵母细胞的潜在作用机制。

期刊介绍: Human Fertility is a leading international, multidisciplinary journal dedicated to furthering research and promoting good practice in the areas of human fertility and infertility. Topics included span the range from molecular medicine to healthcare delivery, and contributions are welcomed from professionals and academics from the spectrum of disciplines concerned with human fertility. It is published on behalf of the British Fertility Society. The journal also provides a forum for the publication of peer-reviewed articles arising out of the activities of the Association of Biomedical Andrologists, the Association of Clinical Embryologists, the Association of Irish Clinical Embryologists, the British Andrology Society, the British Infertility Counselling Association, the Irish Fertility Society and the Royal College of Nursing Fertility Nurses Group. All submissions are welcome. Articles considered include original papers, reviews, policy statements, commentaries, debates, correspondence, and reports of sessions at meetings. The journal also publishes refereed abstracts from the meetings of the constituent organizations.
