OBJECTIVE Ovarian hyperstimulation syndrome (OHSS) is a serious iatrogenic condition, predominantly related to the hormone used to induce oocyte maturation during IVF treatment. Kisspeptin is a hypothalamic neuropeptide that has recently been demonstrated to safely trigger final oocyte maturation during IVF treatment even in women at high risk of OHSS. However, to date, the safety of kisspeptin...

BACKGROUND Ovarian Hyperstimulation Syndrome (OHSS) is a severe health complication observed in some patients undergoing hormonal stimulation during IVF. Presence of OHSS is often associated with a high count of growing follicles responding to FSH hyperstimulation. However, the number of responding follicles may not be sufficient enough to predict the onset and severity of OHSS. The aim of this...

Two cases of women who developed internal jugular vein (IJV) thrombosis associated with ovarian hyperstimulation syndrome (OHSS) are reported in this article. There are 27 cases of IJV thrombosis associated with in vitro fertilisation (IVF) reported in the literature, and in 78% of cases, this outcome was following OHSS. The hypercoagulable state of OHSS increases the risk of venous thromboembo...

Ovarian hyperstimulation syndrome (OHSS), a life-threatening complication occurring in stimulated ovarian cycles, arises from treatment with gonadotropin for induction of follicular maturation in infertile women. Clinical characteristics of OHSS include ascites and pleural effusion induced by increased vascular permeability, where vascular endothelial growth factor (VEGF) was suspected to be th...

OBJECTIVE To evaluate the efficacy and safety of outpatient management of severe ovarian hyperstimulation syndrome (OHSS) requiring placement of a pigtail catheter. METHODS retrospective analysis of thirty-three consecutive patients who underwent in-vitro fertilization (2003-2009) and developed severe/critical OHSS requiring placement of a pigtail catheter. Patients who were managed on outpat...

Ovarian hyperstimulation syndrome (OHSS) is a serious complication of assisted reproduction techniques using in vitro fertilization and intracytoplasmic sperm injection (IVF/ICSI). Its etiology has still not yet been fully resolved. Human chorionic gonadotrophin, administered exogenously as well as produced endogenously during pregnancy, is responsible for the onset of OHSS, and high levels of ...

Background: Ovarian Hyper stimulation syndrome (OHSS) is infrequent and iatrogenic complication of ovary stimulation by Follicular stimulating hormone (FSH). OHSS is a probable complication of ovulation stimulating drugs, including clomiphene citrate and gonadotropins. Development of infertility treatment with the aim of reaching the desirable number of oocyte and embryo has led to ovary stimul...

Ovarian hyperstimulation syndrome (OHSS) is an uncommon complication of controlled ovarian hyperstimulation. Although principal risk factors for OHSS have been determined, unfortunately, to date we are unable to precisely predict the appearance of OHSS. Still more infrequent are thromboembolic complications of OHSS. The background for the increased blood clotting in such cases includes, but is ...

The aim of this study was to compare the branched-chain amino acid (BCAA) and tyrosine concentration in the follicular fluid of infertile women with and without ovarian hyperstimulation syndrome (OHSS) in an in vitro fertilization program combined with controlled ovarian stimulation. Follicular fluid was aspirated during oocyte retrieval from 20 infertile patients who developed moderate-to-seve...

Ovarian hyperstimulation syndrome (OHSS) is a potentially life-threatening complication of pharmacological ovarian stimulation. It is seen in approximately 2 % of all IVF cycles. The prevalence of moderate to severe OHSS ranges from 1 to 10 % in major IVF programs. Severe forms complicate 1 % of IVF cycles and are characterized by massive ovarian enlargement together with a fluid shift into ext...
