Objective In vitro maturation (IVM) is an artificial reproductive technology in which immature oocytes are harvested from the ovaries and subsequently matured in vitro. IVM does not require ovarian hyperstimulation and thus the risk of ovarian hyperstimulation syndrome (OHSS) is avoided. In this multicenter prospective cohort study we assessed the live birth rate per initiated in vitro maturati...

BACKGROUND A bolus dose of GnRH agonist can substitute for hCG as a trigger for the resumption of meiosis in ovarian stimulation with GnRH antagonists, which has been suggested to reduce the risk of ovarian hyperstimulation syndrome (OHSS). As the efficacy of this measure in fresh embryo transfer (ET) cycles is unclear, we evaluated a new clinical concept of GnRH-agonist triggering. METHODS I...

Ovarian hyperstimulation syndrome (OHSS) is a severe iatrogenic complication of controlled ovarian stimulation. Randomised controlled trials (RCTs) have proven several pharmacologic interventions to be effective in OHSS prevention, but these trials have seldom compared multiple drugs. We identified randomised controlled trials (RCTs) through June 2015 by searching databases and compared 11 inte...

Ovarian hyperstimulation syndrome (OHSS) is a rare syndrome, characterized by cystic enlargement of the ovaries and fluid shift from intravascular to third space due ovarian neo-angiogenesis increased capillary permeability. It generally iatrogenic, occurring administration human chorionic gonadotrophin (hCG) during assisted reproductive techniques. Spontaneous form OHSS so that easy confuse di...

Ovarian hyperstimulation syndrome (OHSS) is a serious complication of ovulation induction which, at present, is being studied increasingly because of its frequent occurrence as a result of the growing number of in-vitro fertilization (IVF) programmes. The anatomical changes involving enlargement of the ovaries and increased capillary permeability leading to acute fluid shift have been tradition...

OBJECTIVE To describe our experience with aggressive outpatient transvaginal paracentesis to manage ovarian hyperstimulation syndrome (OHSS). DESIGN Retrospective case series. SETTING Private, academically affiliated IVF center. PATIENT(S) Women undergoing assisted reproductive technologies (ART) and having a diagnosis of OHSS. INTERVENTION(S) Management of OHSS with hospitalization or ...

BACKGROUND Anti-Müllerian hormone (AMH) is increasingly used to quantify ovarian reserve, but it has not yet realized its full clinical potential in assisted reproduction technology. We investigated the possible benefits of using novel, stratified ovarian hyperstimulation protocols, tailored to individual AMH levels, compared with conventional stimulation. METHODS Retrospective data were coll...

BACKGROUND Ovarian hyperstimulation syndrome (OHSS) is a serious complication of ovarian stimulation with massive ascites, pleural effusion and hemoconcentration. The pathophysiological signal mechanisms of OHSS are still unclear and merit further investigation. METHODS Various angiogenic cytokines of follicular fluid and ascites of patients with risk of OHSS were measured, and examined for i...
