The aim of this study was to investigate the influence of nitric oxide (NO) donors (S-nitroso-L-
acetyl penicillamine, spermine-NO complex and sodium nitroprusside) and NO synthase …

Oocytes acquire developmental competence with progressive folliculogenesis. Cumulus
oocyte complexes (COCs) from small antral follicles have inherent low competence and are …

In the animal kingdom, maternal control of early development is a common feature. The
onset of zygotic control over early development, defined as the maternal to zygotic transition …

This study assessed the participation of amphiregulin (AREG) and bone morphogenetic
protein 15 (BMP15) during maturation of bovine cumulus-oocyte complexes (COCs) on …

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 …

Background The developmental competence of an embryo is principally dictated by the
oocyte. Usually, oocyte selection is based on morphological properties; however, all …

Adiponectin is an adipokine hormone that influences glucose utilization, insulin sensitivity,
and energy homeostasis by signaling through two distinct receptors, ADIPOR1 and …

Objective To identify the association between oocyte dysmorphisms and blastocyst
developmental competence. Design Case–control study. Setting Private assisted …

Sustaining viable populations of any wildlife species requires a combination of adequate
habitat protection and a good understanding of environmental and biological factors …

Maternal effect senescence, a decline in offspring viability with maternal age, has been
documented across diverse animals, but its mechanisms remain largely unknown. Here, we …
