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…

Abstract Objective Abnormalities in the eutopic endometrium of women with endometriosis may be related to disease-associated infertility. Although previous RNA-sequencing analysis did not show differential expression in endometrial transcri…

Endometriosis-related infertility is associated with oxidative stress (OS). The present study aims to compare serum OS markers of infertile women with endometriosis and controls during the follicular phase of the natural cycle (D1), after p…

Abstract Endometriosis is a chronic inflammatory disorder that is highly associated with infertility. This association seems to be related to oocyte impairment, mainly in the initial stages of endometriosis (minimal and mild), where no dist…

Research questionIs the transcriptome of cumulus cells of infertile women with advanced endometriosis (EIII/IV), with and without endometrioma, altered?DesignIn this prospective case-control study, next-generation RNA sequencing was used to…

RESEARCH QUESTION: Is the profile of microRNA (miRNA) altered in cumulus cells of infertile women with early (EI/II) and advanced (EIII/IV) endometriosis? DESIGN: In this prospective case-control study, a miRNA profile including 754 target…

Abstract Objective Abnormalities in the eutopic endometrium of women with endometriosis may be related to disease-associated infertility. Although previous RNA-sequencing analysis did not show differential expression in endometrial transcri…

Endometriosis is a highly prevalent disease among women of reproductive age and is frequently associated to infertility. However, the mechanisms underlying endometriosis-related infertility are still not completely known. Several studies ha…

STUDY QUESTION: Compared to healthy women, is the profile of transcripts altered in the eutopic endometrium of infertile women with endometriosis during the implantation window (IW)? SUMMARY ANSWER: The eutopic endometrium of infertile wome…

Endometriosis is frequently related to infertility and little is known about the mechanisms underlying this association. Some studies point to an endometrial factor involved in this condition, which could compromise embryo implantation. Pro…

Studies have demonstrated oxidative stress in peritoneal fluid (PF) from women with endometriosis and the importance of enzymatic antioxidant machinery to avoid oocyte oxidative damage. Considering that PF constantly surrounds the ovaries a…

OBJECTIVE: Alterations in endometrial receptivity may be involved in the etiopathogenesis of endometriosis-related infertility. The literature has suggested that patients with endometriosis present progestin resistance, which could affect e…

Os mecanismos envolvidos na etiopatogênese da infertilidade em pacientes com endometriose não foram totalmente elucidados. A infertilidade apresentada por pacientes com as formas moderada e grave (estadios III e IV, respectivamente) seria, …

Early endometriosis is associated with infertility, and oxidative stress may play a role in the pathogenesis of disease‐related infertility. This prospective case‐control study aimed to compare the presence of oxidative stress markers in th…

Alterações moleculares no endométrio eutópico de mulheres com endometriose podem estar envolvidas na infertilidade associada à doença. Este estudo objetivou comparar os genes diferencialmente expressos (DEG) no endométrio eutópico de mulher…

Some studies have demonstrated alterations in the composition of peritoneal fluid (PF) from women with endometriosis. Controversial studies have suggested that impaired oocyte quality may be involved in the pathogenesis of endometriosis-rel…

A deleterious effect of endometriosis on oocyte quality has been proposed. Evidence suggests that cumulus cells could be used as indirect biomarkers of oocyte quality. The PTGS2 gene, which encodes cyclooxygenase 2 (COX-2), is deregulated i…

Endometriosis is frequently associated with infertility and it is believed that the impairment of endometrial receptivity may be one of the mechanisms involved in this condition. Pinopodes are endometrial cycle-dependent structures that see…

Impaired oocyte quality and oxidative stress might be involved in the pathogenesis of endometriosis-related infertility. To improve our understanding of the role of oxidative stress in this condition, we compare eight oxidative stress marke…

This study evaluated the potential protective effect of the antioxidants, l-carnitine (LC) and N-acetyl-cysteine (NAC), in preventing meiotic oocyte damage induced by follicular fluid (FF) from infertile women with mild endometriosis (ME). …

Endometriosis, a highly prevalent gynecological disease, is often associated with infertility, even in its milder forms (minimal and mild endometriosis). However, no consensus has been established with regard to this relationship and the po…

SYSTEMIC AND FOLLICULAR OXIDATIVE STRESS IN INFERTILE WOMEN WITH ENDOMETRIOSIS UNDERGOING CONTROLLED OVARIAN STIMULATION FOR ICSI: IS THERE A ROLE IN THE ETIOPATHOGENESIS OF INFERTILITY? M. G. Da Broi, F. O. Albuquerque, A. Z. de Andrade, R…
