Endometriosis is a chronic, inflammatory, and multifactorial disease characterized by the presence of endometrial tissue outside the uterine cavity, often associated with debilitating symptoms. It affects approximately 10% of women of repro…

ObjectiveTo compare the effectiveness of microfluidic sperm sorting (MC) and traditional density gradient centrifugation (DGC) in reducing sperm DNA fragmentation index (DFI) and evaluate their impact on clinical outcomes in IVF cycles.Meth…

ObjectiveThin endometrium is an increasingly recognized challenge in infertility treatment. This study aimed to compare endometrial gene expression between women with thin and normal endometrial thickness, and also to identify ovarian stimu…

OBJECTIVE: Since cumulus cells (CCs) play an undeniable role in oocyte maturation by producing and transferring important molecules to the oocyte, examining these cells can provide a broad view of the factors affecting oocyte competence. Th…

OBJECTIVE: Endometriosis is a chronic estrogen-dependent inflammatory disease that impairs fertility and quality of life. Dienogest, the current standard therapy, provides symptom relief but does not correct immune imbalance or prevent recu…

OBJECTIVE: The etiopathogenesis of endometriosis-related infertility remains under investigation, including in women with endometriomas. Oocyte quality is believed to play an important role in the impairment of natural fertility in these pa…

Endometriosis is a chronic inflammatory disease that affects around 10% of women of reproductive age and is frequently associated with infertility. Despite its high prevalence in assisted reproductive technology (ART) cycles, the exact mech…

This systematic review and meta-analysis of randomized controlled trials (RCTs) evaluated whether the use of hyaluronic acid (HA)-enriched medium for embryo transfer (ET) improves live birth rates in in-vitro fertilization (IVF) cycles. A c…

OBJECTIVE: To assess the prevalence, authorship, and reliability of educational fertility-related information shared on Brazilian Instagram, measured by the DISCERN instrument. METHODS: This cross-sectional study analyzed public fertility-…

ObjectiveTo detect the presence of seminal HPV and examine its association with semen quality in men from infertile and fertile couples.MethodsThis single-center case-control study involved 50 men from infertile couples and 10 proven-fertil…

ObjectiveThis study aims to evaluate and characterize Assisted Reproductive Technology (ART) cycles, as well as the associated obstetric and neonatal outcomes, in pregnancies resulting from gamete donation at the Public Gamete Bank of the C…

In vitro fertilization (IVF) has transformed infertility treatment, providing options for individuals struggling to conceive naturally, with significant success rates, particularly in women under 35. However, IVF pregnancies are associated …

ObjectiveThis study investigates the effects of Piperine (PIP) on doxorubicin (DOX)-induced changes in mouse ovarian follicles, stromal cells, collagen fibers, and mRNA expression of nuclear factor erythroid 2-related factor (NRF2), superox…

OBJECTIVE: Endometriosis is a gynecological disorder marked by the formation of endometrial tissue (gland and stroma) outside the uterine cavity. Macrophages, erythrocytes, and apoptotic endometrial tissue transplant into the peritoneal cav…

ObjectiveMorphologic assessment of an embryo is a valuable indicator for determining embryo health; however, it does not provide information on the chromosomal status of an embryo. Therefore, this study aimed to investigate the levels of Ap…

ObjectiveTo evaluate the association between antithyroid antibodies detectability and positivity and ovarian reserve. Additionally, we aimed to evaluate the correlation between TSH levels and parameters of ovarian reserve [anti-Mullerian (A…

In assisted reproductive technologies, a major challenge is the relatively low overall success rate, mainly due to the absence of reliable markers for assessing oocyte and embryo quality. This study focuses on identifying new biomarkers in …

Considering the significant exposure to the synthetic compound bisphenol A (BPA), present in a wide range of materials in our daily lives, this article discusses a possible correlation between this substance and human fertility through a bi…

ObjectiveInfertility is a major global health issue, with assisted reproductive technologies (ART) commonly employed as a solution. Although numerous factors related to couple characteristics and ART cycles are implicated in pregnancy outco…

ObjectiveTo explore whether post-embryo transfer (ET) air travel affects in vitro fertilization (IVF) outcomes, addressing the growing concern in medical tourism where patients frequently travel for fertility treatments.MethodsThis retrospe…

OBJECTIVE: To evaluate Dydrogesterone's effectiveness in PPOS protocols for IVF/ICSI or oocyte cryopreservation, focusing on LH surge suppression and metaphase II oocyte yield. METHODS: A retrospective, comparative, single-center study of …

ObjectiveTo investigate the effects of dietary quercetin on the retrieved mouse oocytes and IVF outcomes.MethodsFemale mice were divided into two groups. Mice were given 0.2 mL water without (control group) or with quercetin 30 mg/kg (querc…

ObjectiveTo compare recombinant FSH (rFSH) with highly purified-human menopausal gonadotrophin (hp-hMG) on ovarian response in women undergoing elective fertility preservation (FP).MethodsThis retrospective study included 456 women who unde…

ObjectiveTo examine the relationship between oxidative stress markers and reproductive parameters in women undergoing assisted reproductive treatments, focusing on the interaction between demographic, oxidative, and reproductive factors.Met…

OBJECTIVE: The aim of this study is to evaluate the intensity of five antibodies against extractable nuclear antigens (ENA: RNP, ScL-70, SS-B, SS-A, and Sm) in infertile patients with endometriosis. METHODS: We investigated infertile women…
