OBJECTIVE: To compare the euploidy rate between ovulation suppression protocols using PPOS and GnRH-ant, and to evaluate possible variables associated with euploidy rate such as age, BMI, infertility duration, treatment-related factors, and…
OBJECTIVE: Preimplantation genetic testing improves rates of assisted reproductive technologies success by selecting euploid embryos, reducing implantation failures and miscarriages. However, some factors in women may also impact outcomes, …
OBJECTIVE: To evaluate the effects of COVID-19 vaccination (AstraZeneca® and CoronaVac®) on anti-Müllerian hormone (AMH) levels in threatened women. METHODS: Retrospective cohort study evaluating serum AMH before and up to three vaccinatio…
BACKGROUND: A women's chances of getting pregnant decreases in cases of infertility, which may have several clinical etiologies. The prevalence of infertility is estimated as 10-15% worldwide. One of the causes of infertility is endometrios…
Dynamic mutations in the 5' untranslated region of FMR1 are associated with infertility. Premutation alleles interfere with prenatal development and increase infertility risks. The number of CGG repeats that causes the highest decrease in o…
OBJECTIVE: To evaluate the impact of prior use of combined oral contraceptives in assisted reproduction techniques with ovulation blockade by oral progestin. METHODS: Retrospective cohort study with a single-center convenience sample of pa…
OBJECTIVE: The follicle-stimulating hormone subunit beta gene rs10835638 variant (c.-211G>T) may have detrimental effects on fertility and protective effects against endometriosis. A case-control analysis was performed, aiming to investigat…
OBJECTIVE: Single nucleotide variants have been implicated in the response to fertility treatment and a pharmacogenomic approach may help to customize therapy based on patient genome. We aimed to evaluate the effect, individual and combined…
Infertility is a worldwide concern, affecting one in six couples throughout their reproductive period. Therefore, enhancing the clinical tools available to identify the causes of infertility may save time, money, and emotional distress for …
Background: Homocysteine levels can be impacted by enzymes variations. Aim: To correlate MTHFR, MTR and MTRR variants with homocysteine levels in the blood and follicular fluid and assisted reproduction results. Material & methods:MTHFR (rs…
OBJECTIVE: To assess whether there is an association between the level of progesterone on the day of administration of human chorionic gonadotropin and clinical and laboratory characteristics, in addition to the results of in vitro fertiliz…
BACKGROUND: Single nucleotide variants (SNVs) FSHB:c.-211G>T, FSHR:c.919G>A, and FSHR:c.2039G>A were reported to be associated with the variability in FSH and LH levels, and in vitro fertilization (IVF) outcomes. In this study, we aimed to …

The etiology of endometriosis is highly complex, and although it is a benign disease, it has several biological behaviors similar to malignant lesions, including cell invasion, neo-angiogenesis, and decreased apoptosis. Survivin is a protei…
BACKGROUND: The quality of life (QoL) of patients with endometriosis and infertility was assessed in different stages and correlated with the clinical features of the cases. METHODS: The present study was a cross-sectional study; 106 women…
OBJECTIVE: To assess the recovery of thawed blastocysts submitted to quarter laser assisted hatching and examine potential correlations between the procedure and pregnancy rates. METHODS: This cross-sectional study included only single-bla…
OBJECTIVE: To investigate the prevalence and intensity of pain perception during diagnostic hysteroscopy in women and potential related factors. METHODS: A total of 489 women were investigated at an infertility clinic. Fluid diagnostic hys…
INTRODUCTION: Endometriosis is defined as the presence of endometrial-like tissue outside the uterus, associated with chronic and inflammatory reaction. Symptoms range from dysmenorrhea, dyspareunia, chronic pelvic pain, unexplained inferti…
INTRODUCTION: Endometriosis is a common, estrogen-dependent condition, defined as the presence of endometrial-like tissue outside of the uterus, associated with often chronic and inflammatory reaction. The association of endometriosis with …
The STAT4 gene is vital to signaling pathways in the immune response. Immunological alterations are involved in the pathogenesis of endometriosis, and STAT4 polymorphisms may be linked to disease development. This study's aim is to evaluate…
A previous GWAS study performed on Brazilian pooled samples indicated some SNPs (single nucleotide polymorphisms) differentially frequent in infertile patients with endometriosis and controls. Some of them were located in the genes whose bi…
Endometriosis is an estrogen-dependent inflammatory disease that affects a large number of women in reproductive age. Follicle-stimulating hormone (FSH) plays a role in steroidogenesis and acts through a transmembrane glycoprotein, FSH rece…
OBJECTIVE: To evaluate PTPN22 C1858T polymorphism and the risk of endometriosis. METHODS: A meta-analysis of 10 published case-control studies (from four articles), with a total sample of 971 cases and 1,181 controls, was performed. We est…
ABSTRACT Objective To evaluate PTPN22 C1858T polymorphism and the risk of endometriosis. Methods A meta-analysis of 10 published case-control studies (from four articles), with a total sample of 971 cases and 1,181 controls, was performed. …
