Noninvasive bovine oocyte quality assessment: possibilities of a single oocyte culture [PDF]
Theriogenology, 2010 Although bovine embryos are routinely produced in vitro for several decades, there still exists a critical need for techniques to accurately predict the oocyte's developmental competence in a noninvasive way, before the in vitro embryo production procedure.

Endometriosis, Oocyte, and Embryo Quality
Journal of Clinical Medicine, 2023 Endometriosis is a common finding among women with infertility, and women who are diagnosed with endometriosis are almost twice as likely to experience infertility. Mechanisms by which endometriosis causes infertility remain poorly understood. In this review, we evaluate the current literature on the impact of endometriosis on oocyte and embryo quality.

Does Coenzyme Q10 Supplementation Improve Human Oocyte Quality?
International Journal of Molecular Sciences, 2021 Acquiring oocyte competence requires optimal mitochondrial function and adequate ATP levels. In this context, CoQ10 supplementation may improve human oocyte quality and subsequent reproductive performance given its role in ATP synthesis and mitochondrial

Cracking the Code of Oocyte Quality: The Oxidative Stress Link to IVF Success. [PDF]
Int J Mol SciThe success of in vitro fertilization (IVF) and female reproductive capacity are significantly determined by oocyte quality. Increasing data highlights the significance of oxidative stress—a state of imbalance between reactive oxygen species (ROS) and ...

Non-invasive oocyte quality assessment
Biology of Reproduction, 2022 Oocyte quality is perhaps the most important limiting factor in female fertility; however, the current methods of determining oocyte competence are only marginally capable of predicting a successful pregnancy. We aim to review the predictive value of non-

Morphological criteria of oocyte quality
Medicina, 2009 In vitro fertilization technology consists of the selection and fertilization of oocytes, the production and transplantation of embryos to recipients. The quality of oocytes has a direct impact on the fertilization and developmental competence of oocytes.

Calcium signaling in oocyte quality and functionality and its application. [PDF]
Front Endocrinol (Lausanne)Calcium (Ca2+) is a second messenger for many signal pathways, and changes in intracellular Ca2+ concentration ([Ca2+]i) are an important signaling mechanism in the oocyte maturation, activation, fertilization, function regulation of granulosa and ...

Effect of mitophagy in oocytes and granulosa cells on oocyte quality†
Biology of Reproduction, 2020 Mitophagy is the process by which cells selectively remove supernumerary or damaged mitochondria through autophagy, and is crucial for mitochondrial homeostasis and cell survival.

Abnormal cholesterol–cholesteryl ester metabolism impairs mouse oocyte quality during ovarian aging [PDF]
Cellular & Molecular Biology LettersBackground Ovarian aging-induced decline in oocyte quality has been a main issue in women of advanced maternal age. However, the potential mechanism remains elusive, and there are no effective strategies to ameliorate aged oocyte quality.
