Paroxetine, a selective serotonin reuptake inhibitor commonly used to treat various psychiatric disorders, may adversely affect female reproductive function. Although apigenin has been shown to ameliorate reproductive abnormalities and ovar…

Uterine leiomyomas or fibroids, are non-cancerous smooth muscle proliferations of the uterus, occurring mostly in women of reproductive age. Their pathogenesis involves complex growth factor interactions that regulate cellular proliferation…

Vitamin B6 is a coenzyme involved in more than 150 biochemical reactions in the body. Its intake has favorable effects for many diseases like Parkinson's disease, glaucoma, and endometriosis. Vitamin B6 can be obtained from tablets, aqua vi…

Pseudouridine (Ψ), the most abundant RNA modification, plays essential roles in shaping RNA structure, stability, and translational output. Beyond cancer, Ψ is dynamically regulated across numerous physiological and pathological contexts-in…

Human fertility has declined sharply since 1950, and a growing body of evidence suggests that while conventional socioeconomic factors are well-established drivers of the broader demographic transition, they do not fully account for the tim…

The female immune system operates within an evolutionary stability-plasticity trade-off, where the physiological demands of pregnancy necessitate a considerable degree of regulatory T cell (Treg) plasticity. This essential flexibility, howe…

Sexual dysfunction, influenced by hormonal imbalances, psychological factors, and chronic diseases, affects a significant portion of the population. Probiotics, known for their beneficial effects on gut microbiota, have emerged as potential…

Since its inception in 1987, in vitro fertilization (IVF) has constituted a significant medical achievement in the field of fertility treatment, offering a viable solution to the challenge of infertility. The continuous evolution of assiste…

This review article focuses on the role of choline in ovarian follicular development, regulated by nutrient-epigenetic interactions. Choline, a key feed additive, participates in DNA methylation and steroid hormone synthesis via its methyl …

One of the critical challenges in assisted reproductive technology (ART) is the inadequacy of effective regulation of reactive oxygen species. Simultaneously, the endogenous antioxidant defense system plays a significant role in combating o…

Recent discovery of menstruation in the Egyptian spiny mouse (Acomys cahirinus) highlighted this species as a feasible model for the study of menstrual cycle physiology. However, reports on active menstrual bleeding in this animal were cont…

Endometriosis significantly impacts fertility through complex mechanisms. These include chronic inflammation, oxidative stress, and anatomical distortion. These mechanisms impair oocyte quality, embryo development, and implantation. While i…

Sex hormones' and menstrual cycle's effects on cognitive performance remain unclear. This study examined cognitive differences between women across menstrual cycle phases, sex differences between women and men, and hormone-cognition associa…

The pond slider (Trachemys scripta) is native to the southeastern United States but has been introduced all around the world, including to the Canary Islands (Spain), along with other less-common exotic freshwater turtles such as Graptemys …

Significant physiological changes occur in both the fetus and the mother during pregnancy. Urine proteins have been shown to reflect a wide range of physiological and pathological changes in the body. This study employed low-abundance prote…

The protein associated with the silencing information regulator 2-associated enzyme1 (SIRT1) is a highly conserved nicotinamide adenine dinucleotide (NAD+)-dependent deacetylase and a key member of the sirtuin family. SIRT1 plays an essenti…

This study aimed to compare sperm parameters and reproductive outcomes after sperm selection using microfluidic chips versus conventional techniques (swim-up/density gradients). A systematic review and meta-analysis were performed after the…

Extracellular vesicles (EVs) are gaining recognition for their essential role in enhancing gamete quality and improving outcomes in assisted reproductive technologies. These nanosized particles, released by cells, carry proteins, lipids, an…

Incorporating artificial intelligence (AI) into in vitro fertilization (IVF) laboratories signifies a significant advancement in reproductive medicine. AI technologies, such as neural networks, deep learning, and machine learning, promise t…

Endometriosis (EMT) is a common gynecological disease with a strong genetic component, while its precise etiology remains elusive. This study aims to integrate transcriptome-wide association study (TWAS), Mendelian randomization (MR), and b…

The increase in cancer survival rates has put a focus on ensuring fertility preservation procedures for cancer patients. Ovarian tissue cryopreservation presents the only option for prepubertal girls and patients who require immediate start…

The epigenetic phenomenon of genomic imprinting is puzzling. While epigenetic modifications in general are widely known in most species, genomic imprinting in the animal kingdom is restricted to autosomes of therian mammals, mainly eutheria…

An overall in vitro fertilization (IVF) outcome is dynamic. Good oocyte quality is important for achieving a better IVF pregnancy. Various methods have been used for OQ assessment (OQA). However, due to inconclusive evidence, one method's s…

Proteomics can be a robust tool in protein identification and regulation, allowing the discovery of potential biomarkers. In clinical practice, the management of endometrial cancer can be challenging. Thus, identifying promising markers cou…

Corticotropin-releasing factor or hormone (CRF or CRH) and the urocortins regulate a plethora of physiological functions and are involved in many pathophysiological processes. CRF and urocortins belong to the family of CRF peptides (CRF fam…
