In a prospective randomized trial comparing efficacy of double over single intrauterine insemination (IUI), 160 couples with unexplained infertility underwent controlled ovarian hyperstimulation and IUI. The pregnancy rates were similar and statistically not different between groups, suggesting that double IUI added no advantage over single IUI.

This report describes two cases that developed moderate ovarian hyperstimulation syndrome (OHSS) without evidence of haemoconcentration. Both patients developed serious cerebrovascular thrombosis resulting in hemiparesis, and recovered after treatment with anticoagulants. This report emphasizes that other factors may contribute to vascular thrombosis, and illustrates that cerebrovascular accide...

Ovarian hyperstimulation syndrome (OHSS) is a serious and potentially life-threatening complication of controlled ovarian stimulation (COS). OHSS is an iatrogenic complication of ovulation induction, which may cause serious impact on patient’s health. OHSS is the most feared complication of IVF-related ovarian stimulation, which in its severe form leads to hospitalization and in the worst case ...

Abstract Background Polycystic ovarian syndrome (PCOS) cases undergoing in vitro fertilisation (IVF) are widely at risk of hyperstimulation; therefore, elective freezing all embryos to be transferred a later cycle is preferred. We aimed compare the pregnancy outcome between fresh and frozen embryo transfer (ET) PCOS IVF with antagonist induction using human chorionic gonadotropin (HCG) as trigg...

Ovarian hyperstimulation syndrome (OHSS) still remains a life-threatening complication of in vitro fertilization treatment (IVF), keeping patients and especially those, who previously experienced OHSS, from attempting infertility treatment and childbearing. The recent implementation of four new modalities: the GnRH antagonist protocol, GnRH agonist (GnRHa) triggering of ovulation, blastocyst tr...

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 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...
