BACKGROUND: Key roles for epigenetic mechanisms in tumorigenesis are well accepted, while the relationship between gene methylation and malignant transformation of ovarian endometriosis (EMS) was seldom reported. In this study, we aimed to …

BACKGROUND: Menopause results in a lack of regular menstrual cycles, leading to the reduction of estrogen production. On the other hand, ovarian androgen synthesis is still present at reduced levels and requires expression of several steroi…

BACKGROUND: Aim of this prospective, case-control study was to evaluate uterine arteries' blood flow before and after laparoscopic surgery in patients with ovarian endometriosis and its possible correlation with infertility. METHODS: We pr…

BACKGROUND: This study was designed to investigate leptin levels in the fluid in ovarian endometriomas (OEs) and to compare the expression of leptin and its receptors (OBR) in ovarian tissue affected by endometrioma in infertile women to it…

BACKGROUND: Early detection of ovarian cancer remains a challenge due to widespread metastases and a lack of biomarkers for early-stage disease. This study was conducted to identify relevant biomarkers for both laparoscopic and serum diagno…

BACKGROUND: The initial dose of recombinant Follicle Stimulating Hormone [rFSH] to be used in assisted reproduction treatment depends on several factors, mainly the cause of the infertility and the patient's age. For young patients [≤35 yea…

In recent years, the negative impact of oxidative stress on fertility has become widely recognised. Several studies have demonstrated its negative effect on the number and quality of retrieved oocytes and embryos following in-vitro fertilis…

BACKGROUND: Endometriosis is characterized by the presence of functional endometrial tissue outside of the uterine cavity. It affects 1 in 10 women of reproductive age. This chronic condition commonly leads to consequences such as pelvic pa…

BACKGROUND: Pelvic irradiation is essential for improving survival in women with pelvic malignancies despite inducing permanent ovarian damage. Ovarian transposition can be performed in premenopausal women in an attempt to preserve ovarian …

BACKGROUND: The activation of blood coagulation could contribute to the failure of in-vitro fertilization (IVF) techniques. The aim of this study was to assess the predictive value of D-dimer levels for pregnancy outcome in women undergoing…

BACKGROUND: Ovarian hyperstimulation syndrome (OHSS) is the most serious complication of IVF/ICSI therapy. The pathophysiology and etiology of the disease is still not fully clarified. METHODS: To assess whether polymorphisms of the VEGF/V…

BACKGROUND: Various inflammatory cytokines have been implicated in the pathophysiology of severe ovarian hyperstimulation syndrome, as well as, various pregnancy complications, including preterm labor, pregnancy induced hypertension/preecla…

BACKGROUND: Ovarian cancer is the most lethal gynecologic disease due to delayed diagnosis, and ascites production is a characteristic of patients in advanced stages. The aim of this study was to perform the proteomic analysis of ascitic fl…

BACKGROUND: Antiprogestin compounds have been shown to be effective in blocking the growth of ovarian cancer cells of different genetic backgrounds. Herein we studied the anti-ovarian cancer effect of a series of antiprogestins sharing the …

BACKGROUND: Understanding the integration of hormone signaling and how it impacts oncogenesis is critical for improved cancer treatments. Here we elucidate GNAI2 message alterations in ovarian cancer (OvCa). GNAI2 is a heterotrimeric G prot…

BACKGROUND: The aim of our study is to establish the potential role of dual-phase 18F-fluorodeoxyglucose positron emission tomography / computed tomography (FDG-PET/CT) in patients presenting ovarian masses with diffuse peritoneal infiltrat…

BACKGROUND: To evaluate the impact of the presence of endometrioma and laparoscopic cystectomy on ovarian reserve as assessed by serum anti-Müllerian hormone (AMH) level. In addition, factors related to the decline in ovarian reserve were a…

BACKGROUND: Corona radiata cells (CRCs) refer to the fraction of cumulus cells just adjacent to the oocyte. The CRCs are closely connected to the oocyte throughout maturation and their gene expression profiles might reflect oocyte quality. …

BACKGROUND: Early detection of epithelial ovarian cancer (OC) is necessary to overcome the high mortality rate of late stage diagnosis; and, examining the molecular changes that occur at early disease onset may provide new strategies for OC…

Primary non-Hodgkin's lymphoma of the ovary is a rare occurrence. An ovarian involvement by non-Hodgkin lymphoma (NHL) may include one of the four subtypes of lymphoma: diffuse large B-cell lymphoma, Burkitt's lymphoma (BL), lymphoblastic l…

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…

OBJECTIVE: To compare the long term impact on ovarian reserve between laparoscopic ovarian cystectomy with bipolar electrocoagulation and laparotomic cystectomy with suturing for ovarian endometrotic cyst. PATIENT AND METHOD(S): 121 patien…

BACKGROUND: Cell lines are very useful for clinical and basic research. Thus far, only 11 reports have documented the characteristics of ovarian endometrioid adenocarcinoma cell lines in the literature. Due to the scarcity of information, t…

BACKGROUND: Chronological age and oocyte yield are independent determinants of live birth in assisted conception. Anti-Müllerian hormone (AMH) is strongly associated with oocyte yield after controlled ovarian stimulation. We have previously…

During the days August 22-24, 2013 has been held in Harbin (China) an International Consensus Conference aimed to improve the quality and the reporting of the randomized controlled trials (RCTs) in infertility and subfertility field. I, as …
