OBJECTIVE Ovarian hyperstimulation syndrome (OHSS) remains as a clinical problem for hyperresponder patients during controlled ovarian hyperstimulation and in vitro fertilization (COH-IVF) procedure. Herein, we aimed to evaluate the COH-IVF outcomes in hyperresponder patients managed with coasting treatment strategy for OHSS prevention regarding the establishment of clinical pregnancy as an end...

BACKGROUND Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic and potentially life threatening condition resulting from excessive ovarian stimulation. Reported incidence varies from 1% to 10% of in vitro fertilization (IVF) cycles. The factors contributing to OHSS have not been completely explained. The release of vasoactive substances secreted by the ovaries under human chorionic gonado...

The ovarian hyperstimulation syndrome (OHSS) is a consequence of superovulation therapy for assisted conception procedures. This potentiallyfatal condition is avoidable by the judicious use of gonadotropins and carefulmonitoring of stimulation regimens. Women who are at particular risk ofdeveloping the syndrome include those who have polycystic ovaries and thosewho are young (under 30 years). W...

BACKGROUND Controlled ovarian hyperstimulation (COH) which combining GnRH antagonist co-treatment and GnRH agonist trigger with an additional 1500 IU hCG luteal rescue on day of oocytes retrieval, has become a common tool aiming to reduce severe ovarian hyperstimulation syndrome (OHSS). In the present, proof of concept study, we evaluate whether by deferring the hCG rescue bolus for 3 days, we ...

Controlled ovarian hyperstimulation with gonadotropins is followed by Ovarian Hyperstimulation Syndrome (OHSS) in some women. An unidentified capillary permeability factor from the ovary has been implicated, and vascular endothelial cell growth/permeability factor (VEGF) is a candidate protein. Follicular fluids (FF) from 80 women who received hormonal induction for infertility were studied. FF...

An ovarian hyperstimulation syndrome (OHSS) in spontaneous pregnancies is a very rare event. Hence, clinicians might make wrong decisions, such as laparotomy, because of suspicion of an ovarian carcinoma, or severe complications such as renal insufficiency may develop because the diagnosis and treatment of OHSS are delayed. Here we report a case of a woman in the 15th week of gestation, present...

Ovarian hyperstimulation syndrome (OHSS) is a potentially severe complication following ovarian stimulation. It has a clinical spectrum ranging from a mild form, which accounts for most cases, to moderate and severe forms that occur rarely but deserve special attention since they are life threatening [1]. Clinical manifestations of OHSS can be classified into (1) mild, with abdominal distension...

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...

BACKGROUND Intrauterine insemination (IUI) is a commonly used treatment in subfertile couples. We assessed patients' preferences for IUI relative to expectant management. METHODS Forty subfertile couples were offered scenarios in which the treatment-independent pregnancy chance was varied against a fixed pregnancy chance after IUI without or with controlled ovarian hyperstimulation (COH) of 8...

This case report describes the first attempt to treat imminent ovarian hyperstimulation syndrome (OHSS) by using a gonadotrophin-releasing hormone (GnRH) antagonist. A 33 year old, normo-ovulatory woman undergoing in-vitro fertilization received daily subcutaneous injections of 150 IU of recombinant follicle-stimulating hormone (recFSH) from cycle day 2, together with GnRH antagonist (ganirelix...
