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 …

BACKGROUND Non-invasive selection of developmentally competent human oocytes may
increase the overall efficiency of human assisted reproduction and is regarded as crucial in …

BACKGROUND The complexity of fertilization failure during assisted reproductive
technologies (ART) is often under-appreciated, as this failure can occur at any number of …

Cytokines are key regulators of ovarian physiology, particularly in relation to folliculogenesis
and ovulation, where they contribute to creating an environment supporting follicle selection …

It is widely recognized that bi-directional communication exists between the human oocyte
and cumulus cells (CCs) which is essential for the production of competent oocytes. CCs …

Reproductive life span and fertility have been shown to depend on successful early
folliculogenesis, which involves cell-to-cell communication and the concerted regulation of …

This proceedings report presents the outcomes from an international workshop supported by
the European Society of Human Reproduction and Embryology (ESHRE) and Alpha …

BACKGROUND A limitation to our ability to distinguish between developmentally competent
and incompetent eggs is our still only partial knowledge of the critical features that are …

Significance: Four decades have passed since the first successful human embryo conceived
from a fertilization in vitro. Despite all advances, success rates in assisted reproduction …

OBJECTIVE: To assess the real biological efficiency of assisted reproduction technology
(ART) cycles by using a new metric called oocyte to baby rate, where live babies born (LBB) …
