BACKGROUND Implantation is considered as the rate-limiting step in success of assisted reproduction techniques, and intrauterine insemination cycles. It might be affected by ovarian superovulation and endometrial local scratching. OBJECTIVE This study aims to investigate the effect of local endometrial injury on the outcome of IUI cycles. MATERIALS AND METHODS In this randomized clinical tr...

OBJECTIVE To determine if power Doppler ultrasound examination of the endometrium can contribute to a correct diagnosis of endometrial malignancy in women with postmenopausal bleeding and endometrium > or = 5 mm. METHODS Eighty-three women with postmenopausal bleeding and endometrium > or = 5 mm underwent gray-scale and power Doppler ultrasound examination using predetermined, standardized se...

background: the aim of this study was to investigate the percentage of the stem cells population in human endometrial tissue sections and cultured cells at fourth passage. methods: human endometrial specimens were divided into two parts, one part for morphological studies and the other part for in vitro culture. full thickness of human normal endometrial sections and cultured endometrial cells ...

Aim: to evaluate the expression of estrogen (ER) and progesterone (PR) receptors in endometrium during "implantation window" women with a history reproductive dysfunction different endometrial thickness. Materials Methods. A prospective single-center cohort comparative study was conducted. The main group included patients hypoplastic (< 7 mm according ultrasound data on preovulatory days) (n...

BACKGROUND Clomiphene citrate (CC) is most commonly used as a first-line treatment of infertility. However, a disturbance of endometrial growth by the adverse effects of the CC has been recognized. Since a thin endometrium is recognized as a critical factor of implantation failure, preventing CC-induced thinning of the endometrium is important. This study was undertaken to investigate whether t...

BACKGROUND This study investigated the effects of serum estradiol (E2) and progesterone levels on preovulatory endometrial thickness and echogenicity in controlled ovarian hyperstimulation (COH) cycles for in vitro fertilization (IVF). MATERIALS AND METHODS In this retrospective study, we evaluated the data of 241 in vitro fertilization- embryo transfer cycles. Cycles were classified into thr...

BACKGROUND The impact of intramural fibroids on the success of IVF treatment is controversial and the mechanisms leading to poor treatment outcomes remain unknown. We compared endometrial and subendometrial blood flow between women with and without intramural fibroids during IVF treatment. METHODS Three-dimensional (3D) ultrasound examination with power Doppler was performed on the day of ooc...

OBJECTIVE To compare the endometrial echo values obtained by transvaginal ultrasonography with the body mass index of postmenopausal patients; to verify if there is higher prevalence of endometrial thickening in women with body mass index ≥ 30. METHODS This is an analytical and cross-sectional study that evaluated 294 patients. Postmenopausal women were included, and those on hormone therapy ...

BACKGROUND Sildenafil citrate may increase endometrial thickness and affect the outcome of frozen-thawed embryo transfer cycles. OBJECTIVE The aim of this study was to estimate the effect of sildenafil citrate on ultrasonographic endometrial thickness and pattern and to investigate the estrogen level on the day of progesterone administration, the implantation rate and chemical pregnancy rate ...

BACKGROUND The correlation between endometrial thickness and receptivity has been mentioned in various studies. This study investigated the effect of granulocyte colony-stimulating factor in treating thin endometrium of infertile women who were chosen for in vitro fertilization in our infertility clinic in 2014 and 2015. METHODS In this randomized clinical trial, 28 women who were chosen for ...
