BACKGROUND Ovarian hyperstimulation syndrome (OHSS), is characterized by marked ovarian enlargement and acute third space fluid sequestration that almost always develops after hCG administration or in early pregnancy. OHSS is similar to vascular leak syndrome (VLS), which may be attributable to the massive increase in systemic inflammatory cytokines. In the present pilot exploratory case series...

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...

discussion the presence of ohss in spontaneous pregnancy especially in familial pattern may lead us to evaluate some endogenous pathogenic factors. case presentation in this case report, we are going to present two cases of ohss occurring in spontaneously conceived pregnancies. one of the patients mentioned the history of this syndrome in her sister, and the other one confronted with this syndr...

Ovarian hyperstimulation syndrome (OHSS) is an uncommon but serious complication associated with assisted reproductive technology (ART). This systematic review aims to identify who is at high risk, how to prevent OHSS, and the treatment for existing OHSS.

OHSS is self‐limiting, and treatment is primarily supportive with an aim to reduce the incidence of associated complications. The complications of severe OHSS include renal failure, hypovolemic shock, venous thromboembolism, respiratory distress syndrome, and even death. A particularly severe feature of OHSS is thromboembolism, for which a prevalence of 0.78%, has been reported and which accoun...

Ovarian hyperstimulation syndrome (OHSS) is a complication that occurs in the luteal phase of an induced hormonal cycle. In most cases, the symptoms are self-limited, and spontaneous regression occurs [1]. Mild manifestations of OHSS include transient lower abdominal discomfort, nausea, vomiting, diarrhea, and abdominal distension. Life-threatening OHSS can progress to adult respiratory distres...

OBJECTIVE To compare pregnancy rates with fresh and frozen embryo transfer in patients admitted to Royal Jubilee Maternity Service (RJMS), Belfast between January 1st 2004 and December 31st 2005 with ovarian hyperstimulation syndrome (OHSS). METHOD A retrospective analysis of all ART cycles (2,283) carried out in RJMS between January 1st 2004 and December 31st 2005 and of all patients admitte...

OBJECTIVE To investigate the oocyte quality in patients with severe ovarian hyperstimulation syndrome (OHSS). DESIGN Self-controlled clinical study. SETTING University teaching hospital. PATIENT(S) Twenty-two patients from our assisted reproductive technology (ART) program who developed severe OHSS during their first controlled ovarian hyperstimulation for IVF or intracytoplasmic sperm in...

BACKGROUND In assisted reproduction cycles, gonadotropins are administered to obtain a greater number of oocytes. A majority of patients do not have an adverse response; however, approximately 3-6% develop ovarian hyperstimulation syndrome (OHSS). Metformin reduces the risk of OHSS but little is known about the possible effects and mechanisms of action involved. OBJECTIVE To evaluate whether ...

This article reports a case of spontaneous ovarian hyperstimulation syndrome (OHSS) following a thawed embryo transfer cycle. OHSS, a potentially life-threatening condition, is an iatrogenic complication of controlled ovarian stimulation; therefore, it is very important to prevent and treat OHSS during treatment with ovulation-inducing agents. Despite our efforts to prevent OHSS, in this case, ...
