BACKGROUND: Pelvic endometriosis (EM) and adenomyosis (AM) have different effects on the fallopian tube. This study aimed to assess the transport capability of the fallopian tube in women with pelvic EM or AM. METHODS: Twenty women with ute…

Gonadotropin-releasing hormone antagonist (GnRH-ant) has been shown to negatively influence endometrial receptivity. Reducing the GnRH-ant dose during controlled ovarian stimulation (COS) when using a GnRH-ant protocol may be beneficial to …

Study questionIs allograft inflammatory factor-1 (AIF-1), a cytokine associated with inflammation and allograft rejection, aberrantly elevated in in vitro fertilization (IVF) cycles with gonadotropin-releasing hormone (GnRH) antagonist prot…

BackgroundOvarian adenosquamous carcinoma is an extremely rare type of ovarian histology. Platinum-refractory disease is also uncommon, but can be fatal because of the lack of available treatment options. To date, there is no study or case …

AimIgA nephropathy (IgAN) is the major cause of end-stage renal disease(ESRD) in Asia and its pathogenesis is influenced by both genetic and environmental factors. Single nucleotide polymorphisms (SNPs) in IL1R1 and IL-1R2 may be associated…

Primary dysmenorrhoea, defined as painful menstrual cramps in the absence of pelvic pathology, is a common problem in women of reproductive age. Its aetiology and pathophysiology remain largely unknown. Here we performed a two-stage genome-…

OBJECTIVE: To explore the feasibility and efficacy of hysteroscopic excision of myometrial adenomyotic lesions. DESIGN: A case-series study. SETTING: A university medical centre. POPULATION: 51 women with myometrial adenomyosis completed th…

GnRH antagonist negatively affects endometrial receptivity in in vitro fertilization (IVF) cycles, however, its underlying mechanism remains unclear. To explore its target molecules, we studied endometria in the window phase of fixed GnRH a…

Successful embryo implantation requires the establishment of a receptive endometrium. Poor endometrial receptivity has generally been considered as a major cause of infertility. Protein glycosylation is associated with many physiological an…

The oocyte is the largest cell found in multicellular organisms. Mitochondria, as the energy factories for cells, are found in high numbers in oocytes, as they provide the energy for oocyte maturation, fertilization, and embryo formation vi…

PURPOSE: Adenomyosis is a common, benign gynecological condition of the female reproductive tract characterized by heavy menstrual bleeding and dysmenorrhea. Gonadotropin-releasing hormone (GnRH) agonists are one of the medications used in …

Adenomyosis, a benign invasion of endometrium, is closely related to endometriosis. Cysteine-rich 61 (Cyr61), a protein present in all endometrial tissues and menstrual effluents, is known to be associated with endometriosis. However, its r…

ObjectiveOxidative stress is generated during the pathophysiology of endometriosis (EMT). Hydrogen (H2) has been demonstrated as a gas antioxidant. The aim of the present study is to evaluate the protective effect of H2 on EMT in rats.Study…

Dear Editor: Endometriosis is defined as the presence of endometrial-like tissue outside the uterine cavity. Of all the cases of endometriosis, intestinal endometriosis accounting for about 10 %, the rectum and sigmoid colon are the most…

Abnormal gene expression is often detected in various tissues/organs of patients with gynecologic and reproductive diseases. Research efforts on the regulatory mechanisms and molecular pathways will lead to a better understanding of the pat…

Preeclampsia (PE) is a multisystem disorder unique to Homo sapiens that is known to cause maternal and perinatal mortality and morbidity. Between 5-7% of all pregnancies are affected by PE and it is responsible for approximately 50,000 mate…

AimsThe aim of the present study is to investigate the differential expression of CD44, CD47 and c-met in ovarian clear cell carcinoma (OCCC), the correlation in their expression and their relationship with the biological behavior of OCCC.M…

OBJECTIVES: This study is to investigate the role and mechanism of microRNA-202 (miR-202) in endometriosis. METHODS: Forty-five cases of ectopic endometrial tissues, 25 cases of eutopic endometrial tissues and 26 cases of normal endometrial…

ContextLate-term pregnancy may lead to maternal and neonatal morbidity and mortality. Mice null for the progesterone receptor co-regulator Krüppel-like Factor 9 (KLF9) exhibit delayed parturition and increased incidence of neonatal deaths.O…

Objective. To explore the effects of puerarin to treat endometriosis (EMT) model rats and the possible regulatory mechanisms. Methods. EMT model rats were surgically induced by autotransplantion of endometrial tissues. The appropriate dosag…

PIK3R1 (p85α regulatory subunit of PI3K) is frequently mutated across cancer lineages. Herein, we demonstrate that the most common recurrent PIK3R1 mutation PIK3R1(R348∗) and a nearby mutation PIK3R1(L370fs), in contrast to wild-type and mu…

Discovery of the TET/JBP family of dioxygenases that modify bases in DNA has sparked considerable interest in novel DNA base modifications and their biological roles. Using sensitive sequence and structure analyses combined with contextual …

OBJECTIVE: To investigate the efficacy of timely ovulation induction on Infertility women with minimal-mild endometriosis (EMS) after laparoscopy combined with hysteroscopy. METHODS: A randomized controlled trial was performed on 132 infert…

Background and objectivesPuerarin, a phytoestrogen with a weak estrogenic effect, binds to estrogen receptors, thereby competing with 17β-estradiol and producing an anti-estrogenic effect. In our early clinical practice to treat endometrios…
