In an attempt to explore the early developmental arrest in embryos from polycystic ovarian syndrome (PCOS) patients, we sequenced the transcriptome profiles of PCOS arrested 2-cell embryos, non-PCOS arrested 2-cell embryos and non-arrested 2-cell embryos using single-cell RNA-Seq technique. Differential expression analysis was performed using the DEGSeq R package. Gene Ontology (GO) enrichment was analyzed using the GOseq R package. Data revealed 62 differentially expressed genes between non-PCOS arrested and PCOS arrested embryos and 2217 differentially expressed genes between PCOS arrested and non-arrested 2-cell embryos. A total of 49 differently expressed genes (DEGs) were annotated with GO terms in the up-regulated genes between PCOS arrested and non-PCOS arrested embryos after GO enrichment. A total of 29 DEGs were annotated with GO terms in the down-regulated genes between PCOS arrested and non-arrested 2-cell embryos after GO enrichment. These data can provide a reference for screening specific genes involved in the arrest of PCOS embryos.

Background: Infertility is a growing global challenge, with ARTs significantly improving birth rates for infertile couples. However, ART conceptions are associated with a higher risk of negative obstetrical and perinatal outcomes, with potential long-term effects on offspring health. Many pre-implantation embryos exhibit abnormal morphokinetics, implantation failure, or arrested development.

Polycystic Ovary Syndrome (PCOS) is the most common endocrine disorder among women of reproductive age, with a prevalence estimated between 10-13%. It is characterized by ovulatory dysfunction, hyperandrogenism, and polycystic ovarian morphology. Anti-Müllerian hormone (AMH) plays a key role in regulating normal reproductive function in both males and females.

: Ovarian follicular cysts (OFCs) in dairy cows represent a significant cause of infertility and share striking similarities with polycystic ovary syndrome (PCOS) in women. This study aimed to elucidate the molecular mechanisms underlying OFCs and their relevance to PCOS by profiling differentially expressed (DE) microRNAs (miRNAs) and constructing integrative RNA interaction networks. : Expression analysis of 84 bovine miRNAs was conducted in antral follicular fluid from normal and cystic follicles using miScript PCR arrays.

Infertility affects 17.5% of couples worldwide, and is notably caused in females by ovarian disorders that impact follicle development and oocyte maturation. Polycystic ovary syndrome (PCOS), affecting 8 to 13% of women of reproductive age, is a leading cause of anovulation and is characterized by arrested antral follicle development before the preovulatory stage.

Polycystic ovary syndrome (PCOS) is the most prevalent ovarian endocrine disorder in infertile women and significantly impacts their health. Granulosa cell (GC) is the largest functional cell type in follicular development and plays a crucial role in follicle growth, differentiation, and maturation. Studies have shown that women with PCOS experience abnormal GC proliferation and apoptosis, which contribute to symptoms such as inflammation, irregular estrous cycles, hormonal imbalances, and follicular development arrest.
