PurposePrevious studies reported that patients with endometriosis had excess nitric oxide (NO) in the reproductive tract and poor embryo development in IVF cycles. This study aims to elucidate the effects of NO on early embryo development.M…
OBJECTIVE: Insertion of the levonorgestrel-releasing intrauterine system Mirena is difficult in women with adenomyosis, and the device is often subsequently expelled. We used a novel insertion technique (Yang's method) to overcome this prob…
ObjectiveTo investigate cell invasiveness and the production of matrix metalloproteinase-2 (MMP-2), MMP-9, tissue inhibitor of metalloproteinase-1 (TIMP-1) and TIMP-2 in endometrial stromal cells (ESCs) of adenomyosis.DesignProspective stud…
BACKGROUND: The eutopic endometrium in a woman suffering from adenomyosis is known to be biologically different from that of healthy women. The aim of this study was to examine the apoptosis and proliferation of eutopic endometrium from wom…
Adenomyosis is a common gynecological disorder that is characterized by the presence of ectopic endometrial glands and stroma embedded within the myometrium with adjacent smooth muscle hyperplasia. Menorrhagia, dysmenorrhea, metrorrhagia an…
ObjectiveTo examine changes in local cytokine production in the eutopic endometrium of adenomyosis after treatment with medroxyprogesterone acetate (MPA) and danazol.DesignProspective cohort study.SettingTertiary university hospital.Patient…
PurposeTo evaluate the effect of extended estrogen administration for women with thin endometrium in frozen-thawed in-vitro fertilization (IVF) programs.MethodsThirty-six women undergoing IVF program had thin endometrium (<8 mm). Among them…
PROBLEM: To determine the effects of macrophage on endometrial stromal cells (ESCs) in women with adenomyosis. METHOD OF STUDY: Eutopic endometrium was obtained and separated into single ESC in 10 women with adenomyosis (study group) and 1…
BACKGROUND: Increased expression of killer cell inhibitory receptors (KIRs) has been found on natural killer (NK) cells in peritoneal fluid in women with endometriosis. In this study, we tried to measure the expression of KIRs on NK and T c…
Women who had stage III-IV endometriosis and who were nulliparous or who had delivered no more than two children were much more likely to develop tubo-ovarian abscesses than those without endometriosis.
BACKGROUND: Previous studies have shown that peritoneal macrophages from women with endometriosis produce excess nitric oxide (NO). This study was designed to quantify the amount of NO and determine the expression of endothelial (eNOS) and …
PROBLEM: To review the literature on the role of peritoneal cytokines in the pathogenesis and endometriosis-related infertility. METHODS OF STUDY: A MEDLINE search was conducted by the key words of cytokine and endometriosis in the English …
BACKGROUND AND PURPOSE: Treatment of endometriosis-associated infertility has not yet become standardized. Various protocols including surgical treatment, medical therapy, and a combination of both have been suggested but their use remains …
BACKGROUND: To determine whether there is a factor (or factors) in the peritoneal fluid of endometriosis patients that impairs embryo growth and embryo implantation. METHODS: Growth and development of two-cell mouse embryos which were cult…
ObjectiveMalfunction of peritoneal natural killer cells (NK) may result in endometriosis. The present study was designed to determine whether the decrease in NK cytotoxicity occurs at early and advanced stages of endometriosis and is due to…
The aims of this study were to determine if differences in serum pro-inflammatory cytokines, vascular endothelial growth factor (VEGF) and clinical pregnancy rate, could be observed in women with severe ovarian hyperstimulation syndrome (OH…
PROBLEM: To verify whether the peritoneal macrophage (PM) is activated in endometriosis. METHOD OF STUDY: We examined the synthesis of nitric oxide (NO), total antioxidant, interleukin (IL)-6, IL-10, and IL-12 by cultured PMs, which were ei…
To clarify the effect of peritoneal fluids (PF) of women with various stages of endometriosis on sperm motility, we utilized computer-aides sperm analysis (CASA) to analyze sperm movement characteristics. PF was collected in the early folli…
PROBLEM: An immunologic basis has long been considered to be very important in the pathogenesis of endometriosis. Interactions of the peritoneal cells, which comprise macrophages, B cells, T cells, natural killer (NK) cells, and retrograde …
This study was performed to determine whether peritoneal T cells are suppressed in the CD4+ or CD8+ T cell subpopulation and whether they are Th1 or Th2 predominant in women with endometriosis. Immune cells in the peritoneal fluid (PF) were…
To explore the role of nitric oxide (NO) and oxidative stress in the pathogenesis of adhesion formation and in endometriosis-associated infertility, we examined the peritoneal total antioxidant status (TAS) and the concentrations of product…
