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...

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...

Ovarian Hyperstimulation Syndrome (OHSS) is a rare complication of super ovulation and in vitro fertilization (IVF). Although our understanding of its pathophysiology is incomplete, induction of development of multiple follicles, perturbation of the renin angiotensin system and exposure to luteinizing hormone (LH) or human chorionic gonadotropin (hCG) are essential contributing factors to its d...

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...

BACKGROUND Many theories regarding the pathophysiology leading to ovarian hyperstimulation syndrome (OHSS) have been proposed and tested. Increased erythrocyte aggregation is associated with capillary slow flow and tissue hypoxaemia. We performed this study in order to assess the degree of erythrocyte aggregation in the peripheral blood of individuals with OHSS and undergoing controlled ovarian...

This study was conducted to investigate the possible role of angiogenin in the pathogenesis of ovarian hyperstimulation syndrome (OHSS). The study group consisted of 10 healthy women who developed severe OHSS (group A) following ovarian stimulation by a long protocol of gonadotrophin-releasing hormone analogues/human menopausal gonadotrophin for in-vitro fertilization. A control group B (n = 10...

Background: This study intends to present the role of rescue in vitro maturation (IVM) in polycystic ovarian syndrome(PCOS) patients undergoing in vitro fertilization (IVF) treatment who have inappropriate responses to ovarianstimulation.Materials and Methods: This was a retrospective case series study of five PCOS patients undergoing IVF treatmentconsidered for cycle ca...

BACKGROUND Spontaneous ovarian hyperstimulation syndrome (sOHSS) can occur following hypothyroidism. Ultrasonography facilitates diagnosis and monitoring of this syndrome. We describe ovarian sonographic changes in a hypothyroid patient with sOHSS after treatment with levothyroxine (l-T4). CASE PRESENTATION A 15-year-old girl presented with abdominal pain and distension for a few months. On e...

AIM We intended to establish the threshold of Anti-Mullerian Hormone (AMH) for detection of Ovarian Hyper-Stimulation Syndrome (OHSS) and poor response to treatment in Iranian infertile women. METHODS Pre-stimulation menstrual cycle day-3 hormonal indices including basal AMH values were measured in 105 infertile women aged 32.5 ± 4.3 years. Patients underwent long GnRH agonist Controlled Ovar...
