BackgroundA growing number of couples worldwide are seeking in vitro fertilization-embryo transfer (IVF-ET) to achieve pregnancy. However, failed IVF-ET treatment inflicts multidimensional stress on patients, involving i...

Abstract Background To evaluate the association between in vitro fertilization (IVF) conception and early hematological indices reflecting erythrocyte heterogeneity and platelet characteristics in preterm infants, and to...

IntroductionInfertility treatment may be influenced by systemic metabolic and redox imbalances. This prospective observational (cross-sectional) study aimed to evaluate the impact of clinical risk factors on oxidative st...

ABSTRACT Background and Aims The imbalance of oxidants and antioxidants mediates cell damage through a phenomenon known as oxidative stress. The increase in fertility problems led to a growing focus on factors that affec...

Abstract Background Chronic endometritis (CE) has two principal subtypes—non-specific chronic endometritis (NSCE) and endometrial tuberculosis (ETB). Both can adversely affect embryo implantation. Although ETB is gener...

This study aimed to investigate how levels of serum follicle-stimulating hormone (FSH) on Day 7 of ovarian stimulation are related to the number of oocytes retrieved, and identify any cutoff or threshold point in protoco...

Background and Aim: Cryopreservation of boar semen is widely used for genetic conservation and artificial insemination; however, it induces oxidative stress and molecular alterations that compromise sperm function. Epige...

Abstract Diminished ovarian reserve (DOR) lacks strong plasma biomarkers, and recent studies have implicated lipid remodeling in its pathophysiology. In our previous study, we noted elevated circulating levels of semapho...

BackgroundPolarized light (PL) imaging provides a noninvasive strategy to assess oocyte quality and maturity. This prospective study aims to identify PL parameters in metaphase II (MII) oocytes that serve as adjunctive i...

Objective: To investigate the incidence, risk factors, and prevention strategies for adnexal torsion (AT) following in vitro fertilization (IVF) procedures at a high-volume fertility center. Methods: A retrospective cas...

Abstract Background Serum beta-human chorionic gonadotropin (β-hCG) hormone is a well-established biomarker used for pregnancy monitoring and prognosis in in vitro fertilization (IVF) cycles. After embryo transfer, a hi...

BackgroundCommon variable immunodeficiency (CVID) is diagnosed at ages ≥4 years with hypogammaglobulinemia across more than two immunoglobulin classes, leading to impaired vaccine responses, frequent infectious, autoim...

ObjectivePolycystic ovary syndrome (PCOS) is a complex endocrine disorder. In this study, we characterize serum bile acids (BAs) metabolic profiles in PCOS patients using targeted metabolomics and investigated their corr...
