The vitrification of ovarian follicles is a strategic tool that may contribute to advances in aquaculture and the conservation of many important species. Despite the difficulties inherent to the cryopreservation of oocytes, some successful protocols have been developed for different species, but little is known about the capacity of oocytes to develop after thawing. Therefore, the profiles of the reproductive pathway genes and fatty acid membrane composition during the initial stages of development were analyzed in fresh ovarian follicles and follicles after the vitrification process. There were differences in the expression of the hypothalamic-pituitary-gonad axis genes during the follicular development in the control group as well as in the vitrified group. Similarly, alterations in the composition of fatty acids were observed after vitrification. Despite this, many alterations were observed in the vitrified group; more than half of the stage III ovarian follicles were able to grow and mature in vitro. Therefore, the vitrification of ovarian follicles may impact them at molecular and membrane levels, but it does not compromise their capability for in vitro maturation, which indicates that the technique can be a strategic tool for aquaculture.

The gut microbiota, comprising trillions of bacteria, fungi, and viruses, exists in symbiosis with the host. As the largest microbial ecosystem in the human body. The gut microbiota not only shapes the homeostasis of the intestinal microenvironment through gut-derived metabolites but also exerts regulatory effects on the functions of diverse tissues and organs throughout the body via the intricate "gut-distal organ axis" mechanism.

Introduction: Several studies indicate that a specific genotype profile could influence ovarian sensitivity to exogenous gonadotropin. However, most of the previous studies were observational and retrospective and thereby more prone to bias. The aim of this study was to evaluate the impact of gonadotropin single nucleotide polymorphisms (SNPs) on the outcomes of fertilization (IVF) in infertile patients undergoing their first ovarian stimulation (OS) cycle.

Diminished ovarian reserve (DOR) poses significant challenges in reproductive health, with emerging evidence implicating DNA damage repair pathways. While GADD45A is a critical regulator of DNA repair, cell cycle and apoptosis, its role in DOR pathogenesis remains unexplored. We employed transcriptome sequencing, qPCR and Western Blot analyses to compare GADD45A expression in granulosa cells (GCs) between DOR patients and controls.

Irisin, a myokine/adipokine released during physical activity, has attracted attention for its regulatory effects on various physiological processes, including metabolism and reproduction. This study was performed to investigate the presence of fibronectin type III domain-containing protein 5 (FNDC5) in chicken granulosa cells (GCs) using immunocytochemistry and to assess the effect of irisin, the extracellular fragment of FNDC5, on these cells, which play a crucial role in progesterone (P4) production and follicle maturation. We measured cell viability, mRNA expression of the luteinising hormone receptor (LHR), the expression of steroidogenic genes (StAR, CYP11A1, and 3BHSD), and P4 secretion in GCs of chicken ovarian follicles.
