BACKGROUND Polycystic ovarian syndrome (PCOS) causes a significantly increased risk of ovarian hyperstimulation syndrome (OHSS). Here, we focused on the altered expression of serum miRNAs and their predictive value for OHSS in PCOS patients. METHODS We used the TaqMan low density array followed by individual quantitative reverse transcription-polymerase chain reaction to identify and validate...

Vascular endothelial growth factor (VEGF) is stated to be a possible promoter of the development and the severity of ovarian hyperstimulation syndrome (OHSS). The secretion of VEGF in granulosa cells seems to be human chorionic gonadotrophin (HCG) dependent. In this prospective study, the data of 10 patients suffering from severe OHSS with ascites and pleural effusions (haematocrit, fluid balan...

Ovarian hyperstimulation syndrome (OHSS) is a serious and potentially life-threatening complication of ovulation induction. The syndrome almost always presents either after hCG administration in susceptible patients or during early pregnancy. Despite many years of clinical experience, the pathophysiology is poorly understood and there is no reliable test to predict patients who will subsequentl...

ART is proven of great help to all the infertile couples anxious to get pregnant , but is not free of side effects and complications. OHSS one of the most important complication especially in cases of PCOS. Ovarian hyperstimulation syndrome (OHSS) is a potentially fatal complication of ovarian stimulation. The incidence has been estimated at 3 to 6% for moderate and 0.1 to 2% for severe OHSS. T...

We report a young woman with spontaneous ovarian hyperstimulation syndrome (OHSS), headaches, visual field defect and pituitary macroadenoma. She underwent transsphenoidal surgery with remission of OHSS. Immunohistochemical staining was positive for β-FSH and β-LH. Recurrence occurred after four years. The patient was treated with octreotide administration and conventional radiation therapy. Oc...

Ovarian hyperstimulation syndrome (OHSS) is a potentially life-threatening complication, usually iatrogenic after ovulation induction. OHSS is a very rare event in spontaneously conceived pregnancies. Only few cases have been reported in literature to the best of our knowledge. We report a very rare case of spontaneous critical OHSS (according to classification of severity of OHSS as mentioned ...

BACKGROUND Ovarian hyperstimulation syndrome (OHSS) in IVF/ICSI cycles may occur either as an early (early onset) or a late pattern (late onset). This observational study was designed to identify whether the onset pattern of OHSS is associated with the occurrence of pregnancy and the early pregnancy outcome. METHODS Among 4376 consecutive IVF/ICSI cycles, 113 patients were hospitalized for OH...

BACKGROUND The role of intravenous (IV) albumin administration in the prevention of ovarian hyperstimulation syndrome (OHSS) and in the improvement of IVF conception outcomes was evaluated in a prospective, randomized, placebo-controlled double blind study. METHODS Ninety-eight women were enrolled in the study and were consecutively assigned to either a treatment group or a control group. Ele...

The cascade of events that leads to the development of ovarian hyperstimulation syndrome (OHSS) is almost always accompanied by elevated estradiol (E(2)) levels. The role of estrogen level in OHSS has not been confirmed; however, it was shown repeatedly in the literature that elevated levels of E(2) constitute a risk for OHSS. Monitoring E(2) was found to be effective in reducing the incidence ...

We aimed to present the management, hospitilization time, pregnancy rates and complications of our polycystic ovary syndrome (PCOS) patients that we treated for OHSS in our clinic. Therefore this study is designed by analyzing of retrospectively collected data of 31 PCOS patients who were treated for OHSS. Diagnosis of PCOS is based on Rotterdam criteria that is published in 2003 and OHSS diagn...
