Summary: This study demonstrates that exposure of pregnant mice to bisphenol A (BPA) can lead to transgenerational transmission of obesity in F2 progeny up to the F6 generation. Chromatin accessibility analysis reveals alterations near binding motifs for CCCTC-binding factor (CTCF) at two cis-regulatory elements of the Fto gene, which correlate with the transmission of obesity. The interaction between these cis-regulatory elements and the Irx3 and Irx5 genes, involved in the differentiation of appetite-controlling neurons, is increased in sperm of obese mice. Deletion of the CTCF site in Fto results in mice that have normal food intake and fail to become obese when ancestrally exposed to BPA.

Summary: The oocyte plays a crucial role in embryo development, with cell-to-cell and cell-to-matrix communications being key for oocyte's developmental competence. Pannexins and Connexins are families of channels that are important for various physiological and pathological processes related to oocyte development and fertility.

Summary: This review article discusses the diverse functions of PARP1 in the regulation of gene expression, focusing on the interaction with transcription factors and the chromatin remodeling dependent or independent of DNA damage. The molecular action mode of PARP1 in gene transcription may present as a potential target for therapeutic intervention of inflammation-related diseases and also for cancer therapy.

Summary: Acquisition of germinal vesicle (GV) stage oocytes for fertility preservation (FP) offers several benefits over in vivo matured oocyte cryopreservation following ovarian stimulation. Two approaches for GV oocytes are available: vitrification before in vitro maturation (IVM) at the GV stage or post-IVM at the metaphase II (MII) stage. This study found that oocyte vitrification at the MII stage after IVM is more suitable for patients who require immediate FP.

Summary: Oocyte cryopreservation (OC) is a process of stimulating ovarian follicles, retrieving follicular fluid, isolating and vitrifying mature oocytes. It has been increasingly used as an option for future biologic children for patients undergoing gonadotoxic therapies. Planned OC, also known as elective OC, is growing in popularity to overcome age-related fertility decline. This review discusses medically indicated and planned OC, focusing on the physiology, technique, timing, financial considerations, and outcomes.

Summary: This study aims to assess Lebanese women's awareness and acceptance of egg freezing and found that factors such as age, marital status, and fertility affect women's attitudes towards the technology. Medical egg freezing is widely accepted and the main indication for social egg freezing is to assist women who struggle to find a suitable partner during their peak fertile years. Concerns about safety and future fertility are among the factors that limit women's decision to undergo the procedure.

Summary: The study found that oocytes collected in spring from prepubertal ewes have higher developmental competence and vitality in in vitro embryo production, with lower production of reactive oxygen species. The research indicates that the season of collection can affect the developmental competence, energetic status, and tubulin assessment of oocytes, emphasizing the importance of considering the season when collecting prepubertal ovine oocytes for in vitro embryo reproduction programs.

Summary: Most women who underwent planned oocyte cryopreservation did so because they didn't want to become pregnant without a partner. While the majority of those who attempted to conceive were successful, some eventually chose to use donor spermatozoa for conception.

Summary: High temperatures can affect follicles and oocytes, leading to impaired follicle development and compromised competence of oocytes to develop into embryos. Studies have shown various mechanisms of oocyte damage due to heat stress, with only subpopulations of follicles affected rather than the entire ovarian reserve.

Summary: This study evaluated the outcomes of patients undergoing planned oocyte cryopreservation, finding that 38.1% of patients took action with their cryopreserved oocytes, while 58.9% did not use them. Further research with larger cohorts and epidemiological comparisons to current egg freezing patients are needed.

Summary: Advanced maternal age (AMA) is associated with decreased quality and quantity of oocytes, making older oocytes more vulnerable to cryo-damage during vitrification. The cellular and molecular features of aged vitrified oocytes exhibit aberrations, leading to delayed embryo development. Collectively, current vitrification protocols optimized for young females may need to be modified for aged women.

Summary: Metabolism is crucial for oocyte quality, with glucose being essential for COC maturation and energy production. Mitochondria are the main ATP source in oocytes, while cumulus cells play a vital role in maintaining ATP levels. New insights in oocyte lipid metabolism and innovative strategies in IVM have shown positive effects on oocyte competence.

Summary: This research reveals the crucial role of Ferroptosis Suppressor Protein 1 (FSP1) in regulating the development and quality of porcine early embryos. Inhibition of FSP1 impairs blastocyst formation, induces glutathione-independent ferroptosis, and leads to oxidative stress due to mitochondrial dysfunction.

Summary: The presence of a more efficient glycolysis mechanism depending on pyruvate in stallion spermatozoa can counteract the detrimental effects of higher glucose concentrations. Incubating spermatozoa with 10 mM pyruvate in a modified Tyrode's media with 67 mM glucose showed increased motility and maintained viability. This improvement is attributed to the conversion of lactate to pyruvate and increased NAD(+) enhancing glycolysis efficiency.

Summary: Ongoing progress in mRNA-Sequencing technologies has contributed to the refinement of assisted reproductive technologies. This study utilized mRNA-Seq datasets of various mammalian species to analyze differential transcript usage (DTU) and identified ten cross-species DTU genes. Gene Ontology (GO) term enrichment analysis revealed the involvement of these genes in RNA and cell-cycle control mechanisms, suggesting their importance during oocyte maturation. Further exploration of these genes' transcript isoforms may lead to the discovery of novel markers for reproductive technologies.

Summary: This study found that Nobiletin (NOB) can promote the cryosurvival and embryo development of porcine sperm after in vitro fertilization (IVF). The addition of NOB improves sperm motility, acrosome integrity, viability, and mitochondrial membrane potential, reduces lipid peroxidation, and increases cleavage and blastocyst formation rates. Furthermore, NOB treatment upregulates the expression of genes related to pluripotency and cell differentiation in the resulting embryos.

Summary: This study investigated the cytotoxicity and toxicological mechanisms of fluorochloridone (FLC) on cultured goat Sertoli cells. The results showed that FLC exposure induced oxidative stress, promoted apoptosis and autophagy, inhibited lysosomal biogenesis, and blocked autophagic flux in goat Sertoli cells. FLC also caused mitochondrial dysfunction and disturbed mitophagy, leading to cell apoptosis. The antioxidant N-acetyl-L-cysteine (NAC) reduced FLC-induced ROS accumulation and reversed the disorder of autophagy levels.

Summary: The study evaluated the effects of E2 treatment on Nelore heifers on day 15 of the estrous cycle, finding that E2 promoted an increase in PGFM concentrations and accelerated functional and structural luteolysis by upregulating the expression of PGR and OXTR. This suggests that within 3 hours after E2 stimulus, the expression of these receptors is associated with triggering luteolysis in cattle.

Summary: This study evaluated the effect of phospholipase C (PLC) on the capacitation of cryopreserved ovine semen. The results showed that the inhibitor U73122 can prevent premature capacitation and acrosome reaction induced by the freezing procedure, without affecting the kinetics and integrity of the sperm membranes.
