BACKGROUND Pain is strongly related to poor quality of life. We performed a cross-sectional study in a university hospital to investigate quality of life in women suffering from chronic pelvic pain (CPP) due to endometriosis and others conditions. METHODS Fifty-seven patients aged between 25 and 48 years-old submitted to laparoscopy because of CPP were(More)
p53 has a crucial role in human fertility by regulating the expression of leukemia inhibitory factor (LIF), a secreted cytokine critical for blastocyst implantation. To examine whether TP53 polymorphisms may be involved with in vitro fertilization (IVF) failure and endometriosis (END), we have assessed the associations between TP53 polymorphism in intron 2(More)
This cross-sectional prospective study assessed follicular-fluid anti-Müllerian hormone (AMH) concentrations in infertile patients with mild/minimal endometriosis during natural IVF. Thirty-two women participated in the study. Patients were divided into two groups: tubal obstruction without endometriosis (control group) and minimal/mild endometriosis (study(More)
In the present study, interleukin (IL)-10, IL-12, IL-17, and IL-23 levels were measured in serum and peritoneal fluid of women with minimal or mild endometriosis and compared with levels in controls without endometriosis. Higher IL-23 levels were encountered in the peritoneal fluid of women with endometriosis, suggesting a possible role of this cytokine in(More)
PURPOSE To evaluate power Doppler ultrasonography to predict sperm recovery in azoospermic patients. METHODS Color Doppler and power Doppler ultrasonography of testis were performed in 38 patients before testicular sperm extraction. Analysis of blood flow included the pulsatility and resistance index of intratesticular vessels and testicular artery, and(More)
Estrogen receptor alpha has a central role in human fertility by regulating estrogen action in all human reproductive tissues. Leukemia inhibitory factor (LIF) expression, a cytokine critical for blastocyst implantation, is mediated by estrogen signaling, so we hypothesized that ESR1 gene polymorphisms might be candidate risk markers for(More)
OBJECTIVES To compare the hysterosonosalpingography(HSS) to the hysterosalpingography(HSG) in the evaluation of the tubal factor in infertility patients. MATERIAL AND METHODS A transversal study with 30 patients in infertility investigation, with age minor than 38 years was performed. The patients were submitted to HSS, HSG and laparoscopy (LPC) in the(More)
BACKGROUND The origin of infertility in patients with endometriosis without tubal occlusion has not yet been clearly defined. Several reports show an abnormal pituitary-ovarian axis in this group of patients. Moreover, prolactin (PRL) and growth hormone (GH) secretion is closely related to reproductive status. This study aimed to evaluate PRL and GH(More)
BACKGROUND In assisted reproduction, hepatitis C virus (HCV) transmission may pose a risk for the baby, technicians, and gametes or embryos from non-contaminated parents. This study aimed at determining the prevalence and risk factors for HCV infection in a group of infertile couples. METHODS HCV infection was investigated in 409 patients attending the(More)
OBJECTIVE To compare the prevalence of dopamine receptor D2 polymorphisms in patients with peritoneal endometriosis and in healthy control subjects. DESIGN Case-control study. SETTING University hospital. PATIENT(S) One hundred seven women aged ≥18 years who were enrolled when seeking care for infertility caused by peritoneal endometriosis or for(More)
