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…

BACKGROUND: Endometriosis is a disease with an unknown pathogenesis that can lead to infertility. Endometrial polyps, fibroids, and polycystic ovarian syndrome (PCOS) have relatively high frequency and are causes of infertility. We hypothes…

Background: Immunological theories suggest that changes in the immune system could prevent the ability to eliminate the endometrium of the pelvic cavity. In women with endometriosis is possible that changes in immunity mediated by T cells f…

PURPOSE: Recently, several genome-wide association studies have demonstrated an association between endometriosis and markers located in or near to WNT4 gene. In order to assess the validity of the findings, we conducted a replication case-…

BACKGROUND: Endometriosis is a chronic condition whose pathophysiology is unknown, but there is evidence suggesting a link with oxidative stress. Paraoxonase is a serum enzyme which circulates associated with high-density lipoprotein (HDL).…

OBJECTIVE: To determine the frequency of the estrogen receptor b gene (ERβ) +1730 G/A polymorphism in infertile women with and without endometriosis and controls. SUBJECTS AND METHODS: Case-control study that included 136 women with endomet…

OBJECTIVE: This study aimed to determine the frequency of the PROGINS polymorphism in women with endometriosis-associated infertility, in infertile women without endometriosis and in controls. INTRODUCTION: The human progesterone receptor g…

OBJECTIVE: To determine the frequency of the estrogen receptor gene (ERbeta) +1730 G/A polymorphism in Brazilian women with endometriosis. DESIGN: Case-control study. SETTING: Endometriosis Outpatient Clinic and Family Planning Outpatient C…
