OBJECTIVE: To investigate the relationship between follicular fluid pentraxin 3 (PTX-3) levels and ovarian response, embryo quality, and insulin resistance (IR) in patients with polycystic ovary syndrome (PCOS) undergoing IVF/ICSI. METHODS…

The therapeutic role and mechanisms of selenium nanoparticles (SeNPs) in cyclophosphamide (CTX)-induced premature ovarian failure (POF) remain unclear. In the present study, female mice were treated with CTX to induce POF, followed by SeNPs…

BACKGROUND: In hormone replacement therapy-frozen-thawed embryo transfer (HRT-FET) cycles, endogenous LH levels may still rise, and the relationship between this and pregnancy outcomes is unclear. The purpose of this study was to investigat…

BACKGROUND: Natural cycle frozen embryo transfer (NC-FET) lowers obstetric risks by preserving ovulation and corpus luteum but limits scheduling flexibility. Natural proliferative phase FET (NPP-FET) offers a scheduling-friendly alternative…

Stem cell research is advancing rapidly, offering substantial promise in reproductive medicine, particularly in addressing infertility and other reproductive disorders. Although recent advances have generated significant interest, the succe…

BACKGROUND: To investigate the impact of Melatonin on follicular oxidative stress and assisted reproductive technology (ART) outcomes in women with diminished ovarian reserve (DOR). METHOD: We put 68 women with DOR who were going through A…

Polycystic ovary syndrome (PCOS) is an endocrine metabolic syndrome characterized by ovulation disorders, hyperandrogenemia, and polycystic ovaries, which seriously affect the psychological and physical health of childbearing women. N6-meth…

Recent evidence suggests a potential association between gut microbiome and ovarian diseases; however, the causal relationship with ovarian cysts remains unclear. In this study, we conducted a two-sample Mendelian randomization (MR) analysi…

BACKGROUND: Hydroxyurea (HU) is an antitumor drug. However, HU exposure is associated with diminished ovarian reserve (DOR). Zi Chong granules, a Chinese Medicine, can protect against DOR, but little is known regarding its underlying mechan…

BACKGROUND: Increased expression of tribbles pseudokinase 3 (TRIB3), which is attributed to increased levels of free fatty acids in the follicular fluid of women with obesity, is correlated with reduced oocyte developmental competence. Conn…

PURPOSE: Hydrosalpinx reduces the pregnancy outcomes of in vitro fertilization and embryo transfer (IVF-ET). Tubal occlusion has been shown to improve IVF-ET success; however, the optimal timing of oocyte retrieval and the molecular changes…

BACKGROUND: Ovarian aging is the main cause of reduced reproductive life span, yet its metabolic profiles remain poorly understood. This study aimed to reveal the metabolic homogeneity and heterogeneity between physiological and pathologica…

BACKGROUND: Polycystic ovary syndrome (PCOS) is one of the most common reproductive endocrine disorders in women of reproductive age and is characterized by a chronic state of excessive inflammation. Increased expression of WNT5A in a varie…

BACKGROUND: Polycystic ovary syndrome (PCOS) is a complex endocrine disorder characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovaries. Despite its prevalence, the underlying mechanisms contributing to the pathogenesi…

OBJECTIVE: Tricho-rhino-phalangeal syndrome-1 (TRPS1), an atypical GATA transcription factor, plays a critical role in diverse physiological and pathological processes and holds potential as a biomarker for diseases and targeted tumor thera…

Ovarian cancer remains the most lethal malignancy of the female reproductive tract. Because early-stage disease is almost silent, roughly 70% of patients present with advanced, disseminated tumors. The current standard-maximal cytoreductive…

BACKGROUND: Vitamins, as essential trace organic compounds for the human body, are crucial substances in the maintenance of normal reproductive function. Nevertheless, the effects of vitamins on the activation of primordial follicles and th…

BACKGROUND: Imbalances in alkali elements (AEs) and alkaline earth elements (AEEs) cause reproductive disorders. However, it remains unclear whether AEs/AEEs in follicular fluid have a relationship with the serious reproductive disorder kno…

OBJECTIVE: To construct a machine learning diagnostic model integrating feature dimensionality reduction techniques and artificial neural network classifiers to develop the value of clinical routine blood indexes for the auxiliary diagnosis…

BACKGROUND: Artificial Intelligence entails the application of computer algorithms to the huge and heterogeneous amount of morphodynamic data produced by Time-Lapse Technology. In this context, Machine Learning (ML) methods were developed i…

OBJECTIVE: To establish a rat model of pharmacological ovariectomy by GnRH-a injection and to preliminarily investigate the reproductive endocrine effects of Xiangshao granules on pharmacologically ovariectomized rats. METHODS: A rat model…

BACKGROUND: Poor ovarian response (POR) to controlled ovarian stimulation (COS) remains challenging, especially in advanced-age women with diminished ovarian reserve, resulting in low live birth rates. Many patients prefer to conceive with …

OBJECTIVE: To investigate the changes in bile acid (BA) metabolites within the follicular fluid (FF) of patients with diminished ovarian reserve (DOR) and to identify novel diagnostic markers that could facilitate early detection and interv…

BACKGROUND: Bisphenol A (BPA), an endocrine disrupting chemical with weak estrogenic and anti-androgenic activity, is widely present in various environmental media and organisms. It has certain reproductive toxicity and can cause a variety …

Ovarian cancer (OC) is the most lethal gynecological cancer in the developed world. Most cases are diagnosed at late stage III-IV with a very low 5-year overall survival rate. Several studies revealed an elevated risk of OC in users of horm…
