The Effect of CoQ10 supplementation on ART treatment and oocyte quality in older women
Human Fertility, 2023 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.

In vivo and in vitro postovulatory aging: when time works against oocyte quality?
Journal of Assisted Reproduction and Genetics, 2022 In mammalian species an optimal fertilization window during which successful fertilization occurs. In the majority of mammals estrus marks ovulation time and coincident with mating, thereby allowing the synchronized meeting in the fallopian tubes ...

Administration of nicotinamide mononucleotide improves oocyte quality of obese mice
Cell Proliferation, 2022 Obesity has become a common health concern around the world. Maternal obesity could cause poor reproductive outcomes due to chronic ovarian inflammation and decreased oocyte quality.

Methods for Assessing Oocyte Quality: A Review of Literature
Biomedicines, 2022 The rate of infertility continues to rise in the world for several reasons, including the age of conception and current lifestyle. We list in this paper potential non-invasive and invasive techniques to assess oocyte quality.

Lipofuscin bodies in human oocytes as an indicator of oocyte quality [PDF]
Journal of Assisted Reproduction and Genetics, 2007 Refractile bodies are one of the main morphological abnormalities that can be observed in the cytoplasm of human oocytes. In the present studies the characteristics of refractile bodies and the relationship between the size of these structures and developmental competence of the affected oocytes and resulting embryos were examined.

The Role of Oocyte Organelles in Determining Developmental Competence
Biology, 2017 The ability of an oocyte to undergo successful cytoplasmic and nuclear maturation, fertilization and embryo development is referred to as the oocyte’s quality or developmental competence.

NAD+ Repletion Rescues Female Fertility during Reproductive Aging
Cell Reports, 2020 Summary: Reproductive aging in female mammals is an irreversible process associated with declining oocyte quality, which is the rate-limiting factor to fertility. Here, we show that this loss of oocyte quality with age accompanies declining levels of the

Oocyte maturation and quality: role of cyclic nucleotides [PDF]
Reproduction, 2016 Abstract The cyclic nucleotides, cAMP and cGMP, are the key molecules controlling mammalian oocyte meiosis. Their roles in oocyte biology have been at the forefront of oocyte research for decades, and many of the long-standing controversies in relation to the regulation of oocyte meiotic maturation are now resolved.
