(Submitter supplied) Although it is well established that the ovarian reserve diminishes with increasing age, and that a woman’s age is correlated to lower oocyte quality, the interplay of a diminished reserve and age on oocyte developmental competence is not clear. After maturation, oocytes are mostly transcriptionally quiescent, and developmental competence prior to embryonic genome activation (EGA) relies on maternal RNA and proteins. more...

(Submitter supplied) Ovulatory dysfunction affects nearly 40% of women of reproductive age that are struggling with infertility. Ovulation is the culmination of a complex and long process during which most follicles undergo atresia instead of developing into preovulatory follicles. The rescue of follicles from atresia and their maturation towards ovulatory competence requires “a pas de deux” between endocrine and locally-produced factors. more...

(Submitter supplied) Granulosa cells mature and die as ovarian follicles enlarge and die (undergo atresia) under the influence of hormones and intrafollicular factors. Later in follicular development, a fluid-filled antrum is formed, a process which is accompanied by a high rate of atresia. These small antral follicles (5 mm or less in diameter in the cow) contain granulosa of 2 different phenotypes, rounded or columnar, whereas follicles larger than 5 mm have the rounded phenotype only. more...

(Submitter supplied) Antral follicle size might be a valuable additive predictive marker for IVF outcome. However, while some studies show positive relations between follicle size and reproductive outcome, others have not been successful in establishing this relation. To better understand consequences of antral follicle size for reproductive outcome, we aimed to obtain insight in follicle size-related granulosa cell processes, as granulosa cells play an essential role in follicular development via the production of growth factors, steroids and metabolic intermediates, needed for follicular growth and oocyte development. more...

(Submitter supplied) Purpose: To investigate the impact of chronically-elevated androgens in presence and absence of an obesogenic diet on oocyte quality in the naturally-selected primate periovulatory follicle. Methods: Rhesus macaques were treated using a 2-by-2 factorial design (n=10/treatment) near onset of menarche with implants containing either cholesterol (C) or testosterone (T; 4-5 fold increase above C) and a standard or “Western-style” diet alone (WSD), or in combination (T+WSD). more...

(Submitter supplied) Background Correct achievement of early ovarian folliculogenesis is a crucial phase for further ovarian function. This process is closely regulated by cell-cell interactions and coordinated expression of genes from oocyte and granulosa cells. But, despite of the large number of studies, little is known about the precise gene expression patterns driving early folliculogenesis. The experimental limitations concerned the very small size of these follicles and the mixture of the different developmental stages within an ovary that make the study of isolated follicular components much more difficult. more...

(Submitter supplied) The oocytes presenting SERa are considered dysmorphic and have been associated with reduced embryological outcome and an increased risk of congenital anomalies. Therefore, in 2011 the Alpha/ESHRE Consensus strongly recommended not to inseminate MII oocytes displaying SERa (SERa+). Not all Centers follow this recommendation and some Authors reported that SERa+ can lead to healthy newborns. Moreover, no experimental data about the effect of SERa presence on the oocyte molecular status are available. more...

(Submitter supplied) In-vitro-grow (IVG) of preantral follicles is essential for female fertility preservation, while effective approach to improve it is far from being explored. Here, we report the dynamic location of TRKB in human and mouse ovaries, and a positive relation between human oocyte maturation and NT-4 level in follicular fluid. For the first time, we observe the improving effect of NT-4 on mice preantral follicle IVG, including follicle diameter, hormone production and oocyte maturation. more...

(Submitter supplied) Human ovarian folliculogenesis is an highly regulated and complex process. Characterization of follicular cell signatures during this dynamic process is important to understand follicle fate (to grow, become dominant or undergo atresia). The transcriptional signature of human oocytes and granulosa cells (GC) in early-growing and ovulatory follicles have been previously described, however that of oocytes with surrounding GCs in small antral follicles have not been studied yet. more...

(Submitter supplied) Multiple pregnancy represents an important health risk to both mother and child in fertility treatment. To reduce a high twin rate, restriction to one embryo transfer is needed. Morphological evaluation methods for predicting embryo viability has significant limitations. Tight communication exists between the follicular cells (FCs) and the oocyte; therefore, developmental competence may be determined by markers expressed in the surrounding FCs. more...

(Submitter supplied) The aim of this study was to assess the impact of oocyte competence on subsequent fertility. Based on knowledge already accessible in mammals and on bioinformatics tools including the chicken genome sequence, we focused on the expression of genes involved in the processes of fertilization and of early embryo development. A differential kinetic study is performed on INRA lines selected on the basis of their fertility potential in purpose of hopefully access gene markers of fertility performance. more...
