Oocyte quality and aging

open access: yesJBRA Assisted Reproduction, 2021
It is well known that female reproduction ability decreases during the forth decade of life due to age-related changes in oocyte quality and quantity; although the number of women trying to conceive has today increased remarkably between the ages of 36 ...

The effects of vitrification on oocyte quality

open access: yesBiology of Reproduction, 2021
Vitrification, is an ultra-rapid, manual cooling process that produces glass-like (ice crystal-free) solidification. Water is prevented from forming intercellular and intracellular ice crystals during cooling as a result of oocyte dehydration and the use

Decreased oocyte quality in patients with endometriosis is closely related to abnormal granulosa cells

open access: yesFrontiers in Endocrinology, 2023
Infertility and menstrual abnormalities in endometriosis patients are frequently caused by aberrant follicular growth or a reduced ovarian reserve. Endometriosis typically does not directly harm the oocyte, but rather inhibits the function of granulosa ...

From Cytoskeletal Remodeling to Oocyte Quality: The Emerging Role of Mechanics [PDF]

open access: yesAdvanced Science
Oocyte quality is essential for successful fertilization and embryonic development. At the end of mammalian oogenesis, oocytes undergo two highly asymmetric meiotic divisions that preserve maternal reserves while generating a haploid gamete.

The role of mitophagy during oocyte aging in human, mouse, and Drosophila: implications for oocyte quality and mitochondrial disease

open access: yesReproduction and Fertility, 2021
There is a worldwide trend for women to have their first pregnancy later in life. However, as oocyte quality declines with maternal aging, this trend leads to an increase in subfertility.

Maternal diabetes and oocyte quality [PDF]

open access: yesMitochondrion, 2010
Maternal diabetes has been demonstrated to adversely affect preimplantation embryo development and pregnancy outcomes. Emerging evidence has implicated that these effects are associated with compromised oocyte competence. Several developmental defects during oocyte maturation in diabetic mice have been reported over past decades.

The effect of endometriosis on oocyte quality: mechanisms, diagnosis and treatment. [PDF]

open access: yesArch Gynecol Obstet
Endometriosis significantly impacts the physical and mental health of women of reproductive age. While some patients can achieve pregnancy through surgery or in vitro fertilization (IVF), many still struggle with IVF failure due to poor oocyte quality ...
