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.

Polyunsaturated fatty acids influence offspring sex ratio in cows [PDF]
, 2018 Dietary polyunsaturated fatty acids (PUFAs) can influence fertility in farm animals. Some evidence in mice and sheep have suggested that PUFAs may influence offspring sex ratio, which may have significant value for cattle production.

Oocyte and embryo quality after coasting: the experience from oocyte donation [PDF]
Human Reproduction, 2002 Oocyte donation provides us with an opportunity to study the clinical outcome of oocytes, retrieved from women undergoing coasting, in recipients in whom endometrial receptivity is unaltered by the coasting procedure. Thus, our aim was to describe oocyte donation outcome in donors undergoing coasting, the oocyte and embryo quality obtained from these ...

Serum AMH level predicts oocytes quality better than follicular fluid AMH level
Asian Pacific Journal of Reproduction, 2016 Background: Current in vitro fertilization (IVF) methods can't predict oocyte quality after oocyte retrieval. Anti-Mullerian hormones (AMH) in the follicular fluid are produced directly by granulosa cells therefore should be considered as parameter for ...

Oocyte-secreted factors: regulators of cumulus cell function and oocyte quality [PDF]
Human Reproduction Update, 2008 Oocyte quality is a key limiting factor in female fertility, yet we have a poor understanding of what constitutes oocyte quality or the mechanisms governing it. The ovarian follicular microenvironment and maternal signals, mediated primarily through granulosa cells (GCs) and cumulus cells (CCs), are responsible for nurturing oocyte growth, development ...

The value of automated follicle volume measurements in IVF/ICSI [PDF]
, 2014 Background/Aims: The objective of this literature study is to investigate the place of recent software technology sonography-based automated volume count (SonoAVC) for the automatic measurement of follicular volumes in IVF/ICSI.

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

Veterinární Medicína, 2015 Developmental competence of female gametes determines their maturation ability, successful fertilisation, and proper zygote formation. Oocyte quality may be assessed by expression profiling of several gene markers such as Cx43, TGFB, GDF9, BMP, Lox and ...
