Ovarian cancer represents the most lethal of the gynecological neoplasms. The molecular and genetic events associated with early ovarian oncogenesis are still largely unknown, thus contributing to the lack of reliable biomarkers for disease detection. Since the majority of ovarian tumors are diagnosed at an advanced stage, the availability of early ovarian cancer tissue samples for molecular an...

MicroRNAs (miRNAs) are endogenous, small, noncoding single-stranded RNA molecules approximately 22 nucleotides in length. miRNAs are involved in the post-transcriptional regulation of various important cellular physiological and pathological processes, including cell proliferation, differentiation, apoptosis, and hormone biosynthesis and secretion. Ovarian follicles are the key functional units...

Background: Ovarian mucinous borderline tumors are divided into two morphologic groups: endocervical-like and intestinal type. Most endocervical adenocarcinomas exhibit mucinous and/or endometrioid differentiation, they infrequently metastasize to the ovaries but may simulate primary ovarian tumors (both atypical proliferative or borderline and carcinoma). In patients with mucinous adenocarcino...

Background and Aim: Ovarian torsion is one of the rare causes of emergency surgeries during pregnancy. Heterotopic pregnancy is a rare type of pregnancy characterized by embryo implantation in two different locations. occurence of these two complications at the same time is a very rare condition. In this study, we present a rare case of heterotopic pregnancy accompanied by ovarian torsion. Pat...

Background: The objective of this study is to establish importance of anti-FSH antibodies in IVF outcome. Materials and Methods: This research was designed based on evaluation of several articles from 2000 till 2012 about anti-FSH antibodies in IVF outcome. Results: Serum concentrations of anti-FSH IgG and IgA were linearly associated with poorer ovarian stimulation outcome. For example 1.0 AU ...

Background: Ovarian cancer is the fifth leading cancer-related cause of death in women worldwide and is often diagnosed at advanced stages. Regarding the low sensitivity and specificity of the currently available diagnostic techniques, in the present study, we aimed to evaluate the accuracy of RMI and ROMA indexes and comparing these two indexes with CA-125 and HE4 parameters for the diagnosis ...

BACKGROUND Accumulating evidence suggests that many ovarian cancers represent metastases from occult fallopian tube carcinomas or tumors arising within ovarian endometriosis. We hypothesized that small ovarian volumes, as reflected in nonvisualization by transvaginal ultrasound (TVU), would be a marker of lower ovarian cancer risk, whereas enlargement on serial examinations would indicate highe...

background: to achieve multiple oocytes for in vitro fertilization, ovulation induction is induced by gonadotropins however, it has several effects on oocytes and embryo quality and endometrium receptivity. the aim of this study was to assess ultrastructural changes of corpus luteum after ovarian induction using human menopausal gonadotropin (hmg) and human chorionic gonadotropin (hcg) during l...

Ovarian torsion is frequently found in benign cases of non-adhered ovarian tumors. When only a simple cyst without surface nodules detected by preoperative imaging, we tend to classify the tumor as benign. We herein report case that presented and was be high-grade serous carcinoma laparoscopic adnexectomy postmenopausal woman.
