Follicular fluid content and oocyte quality: from single biochemical markers to metabolomics

Reproductive Biology and Endocrinology, 2009
The assessment of oocyte quality in human in vitro fertilization (IVF) is getting increasing attention from embryologists. Oocyte selection and the identification of the best oocytes, in fact, would help to limit embryo overproduction and to improve the ...

Supplementation of mitochondria from endometrial mesenchymal stem cells improves oocyte quality in aged mice

Cell Proliferation, 2022
Maternal ageing is one of the major causes of reduced ovarian reserve and low oocyte quality in elderly women. Decreased oocyte quality is the main cause of age‐related infertility.

Estradiol and luteinizing hormone concentrations in the follicular aspirate during ovum pickup as predictors of in vitro fertilization (IVF) outcome

Middle East Fertility Society Journal, 2017
Background: A relationship between ‘oocyte quality’ and follicular fluid hormones is expected, since its formation coincides with the ‘oocyte maturation’ phase.

#149 : Improved Embryo Quality of Infertile Women at Different Ages by Oral Administration of an Antioxidant Mixture

Fertility & Reproduction, 2023
Background and Aims: Oxidative stress is known to affect oocyte/embryo quality. In the previous meeting of ASPIRE, an antioxidant mixture (AOM) developed by us was shown to improve oocyte/embryo quality. Since oxidative stress is related to aging of body,

Nicotinamide Supplementation Improves Oocyte Quality and Offspring Development by Modulating Mitochondrial Function in an Aged Caenorhabditis elegans Model

Antioxidants, 2021
Aging is associated with a decline in the quality of biological functions. Among the aging processes, reproductive aging is a critical process because of its intergenerational effects.

Fumonisin B1 exposure deteriorates oocyte quality by inducing organelle dysfunction and DNA damage in mice.

Ecotoxicology and Environmental Safety, 2021
Oocyte quality is critical for fertilization and early embryo development. Fumonisin B1 (FB1) is a Fusarium mycotoxin and it is commonly found in contaminated food and feedstuff, posing a potential health hazard to both animals and human. FB1 is reported
