Endometrial thickness is defined as the minimal distance between the echogenic interfaces of myometrium and endometrium. An adequate thickness of endometrium is indispensable for embryo implantation [1-4]. The minimum endometrial thickness that may cause a successful implantation is called “threshold thickness”. The endometrium that is thinner than “threshold thickness” is called “thin endometr...

OBJECTIVE In clinical settings, transvaginal ultrasound has been used to evaluate abnormal vaginal bleeding. Because the endometrium responds to estrogens, endometrial thickness may constitute a biomarker of estrogen status in postmenopausal women. This study aimed to validate the transvaginal ultrasonographic measurement of endometrial thickness as an estrogen biomarker in asymptomatic, postme...

OBJECTIVE This study was aimed to investigate endometrial histology and to find predictable clinical factors for endometrial disease (hyperplasia or cancer) in women with polycystic ovary syndrome (PCOS). METHODS We investigated the endometrial histology and analyzed the relationship between endometrial histology and clinical parameters, such as LH, FSH, estradiol, testosterone, fasting and 2...

The aim of this study was to evaluate the effects of low-dose tibolone therapy on ovarian area, uterine volume and endometrial thickness, and define the cut-off value of endometrial thickness for curettage during uterine bleeding. We followed 619 postmenopausal women, aged 40-60 years, for two years. There were 301 subjects in the low-dose tibolone treatment group and 318 subjects in the contro...

BACKGROUND The endometrial hyperplasia measured by ultrasound in polycystic ovary syndrome (PCOS) women is strongly related to pathologic endometrial thickness, but there is no consensus on the relation between serum luteinizing hormone (LH) and either of these factors: pathologic endometrial hyperplasia and body mass index (BMI). MATERIALS AND METHODS In this observational cross-sectional st...

OBJECTIVE To develop and test a risk-scoring model for the prediction of endometrial cancer among symptomatic postmenopausal women at risk of intrauterine malignancy. METHODS We prospectively studied 624 postmenopausal women with vaginal bleeding and endometrial thickness > 4 mm undergoing diagnostic hysteroscopy. Patient characteristics and endometrial assessment of women with or without end...

Adequate growth of the endometrium is an important factor for successful implantation. Some authors have reported that there is a steady and gradual increase in pregnancy rates as endometrial thickness increases [1]. When endometrial thickness is <6 mm, the probability of achieving a full-term pregnancy decreases [2]. In order to maximize pregnancy rates, endometrial thickness from 8 mm to 14 m...

OBJECTIVE Assess the occurrence of endometrial hyperplasia and endometrial cancer among PCOS patients having abnormal menstrual pattern. Endometrial thickness and other clinical characteristics associated with endometrial hyperplasia and endometrial cancer were also evaluated MATERIAL AND METHOD Women with PCOS and abnormal menstrual pattern were enrolled into this cross-sectional study. Endo...

OBJECTIVE In this study, we investigated whether serum androgen levels and endometrial thickness differed in obese and non-obese women. MATERIAL AND METHODS Thirtytwo non-obese (BMI <30) and 48 obese (BMI ≥ 30) women were enrolled. Blood samples were analyzed for testosterone, free testosterone, androstenedione, DHEAS, and SHBG, and transvaginal ultrasonography was performed. RESULTS Obese ...

To determine the role, timing and indications for endometrial hysteroscopic investigation in relation to the clinical, ultrasound and histological features of the endometrium during tamoxifen (TAM) use. We performed an observational longitudinal cohort study (years 2007-2012) that investigated the endometria of 151 TAM users with hysteroscopy and histology. For all patients, gynaecological hist...
