PURPOSE: Anti-Mullerian hormone (AMH) is commonly known as the most potent marker for ovarian reserve due to its decline as female age increases. While serum AMH (sAMH) levels have been intensively investigated, there is less data regarding AMH concentrations in follicular fluid (FF), since FF has usually been designated as waste product during oocyte collection in assisted reproductive technologies. This pilot study investigated follicle AMH concentrations (fAMH) of several follicles per ovary, individually collected with the Steiner-Tan needle, and compared them to sAMH concentrations in women undergoing IVF treatment...

BACKGROUND AND OBJECTIVE: Luteal phase physiology is distorted by in vitro fertilization (IVF) cycles using gonadotropin-releasing hormone (GnRH) agonists and antagonists, Controlled ovarian hyperstimulation leads to luteal phase defect and for this reason, luteal phase support is now an integral part of IVF/ICSI-ET programs. The support is provided by hCG, progesterone or GnRH-a. This study compared the efficiency, safety and tolerance of two vaginal micronized progesterones, Utrogestan and Crinone 8%...

Ovarian hyperstimulation syndrome (OHSS) is one of the most frequent, serious and potentially lethal iatrogenic complications of controlled ovarian stimulation. Despite extensive research, the exact pathogenesis of this syndrome remains less clear, but there appears to be a relationship of increased vascular permeability mediated by HCG and other downstream mediators. Adequate experience with ovulation induction therapy and identifying patients with known risk factors are essential in preventing OHSS. As this is a completely iatrogenic disease numerous strategies have been investigated to help decrease the risk of OHSS and their effects on pregnancy and live birth rate...

The past four decades have delivered many advancements to improve in vitro fertilization (IVF) outcomes. These include a delicate balance of controlled ovarian hyperstimulation (COH) without causing ovarian hyperstimulation syndrome (OHSS), a safe oocyte retrieval, fertilization and embryo culture, endometrial growth and receptivity to promote implantation, and luteal support to maintain the pregnancy. Contemporary IVF practice includes both the classic COH protocols as well as protocols for poor responders and those for specific patient populations...

OBJECTIVE: Controlled ovarian hyperstimulation (COH) promotes multifollicular growth, increasing the chance of obtaining euploid embryos that will successfully implant. Whether aneuploidy is increased from COH with exogenous gonadotropins interfering with natural selection of dominant follicles is a concern. This study evaluates the association between gonadotropin exposure and aneuploidy. METHODS: This is a retrospective cohort study of 828 patients that underwent 1122 IVF cycles involving controlled ovarian stimulation and trophectoderm biopsy for preimplantation genetic screening (PGS), from 2010 to 2015...

Intrahepatic cholestasis of pregnancy (ICP) is an uncommon disorder, which generally occurs in the second and third trimester of pregnancy with symptoms of pruritus. The cause of ICP is unknown but genetic, hormonal and environmental factors contribute to its pathogenesis. The aetiology of ICP is unclear but elevation in oestrogen levels thought to cause ICP is typically seen in the third trimester of pregnancy, and for this reason it is not usually considered in the differential diagnosis of pruritus and liver function disorders in the first trimester of the pregnancy...

In various human diseases, an increase in capillary permeability to proteins leads to the loss of protein-rich fluid from the intravascular to the interstitial space. Although sepsis is the disease most commonly associated with this phenomenon, many other diseases can lead to a "sepsis-like" syndrome with manifestations of diffuse pitting edema, exudative serous cavity effusions, noncardiogenic pulmonary edema, hypotension, and, in some cases, hypovolemic shock with multiple-organ failure. The term capillary leak syndrome has been used to describe this constellation of disease manifestations associated with an increased capillary permeability to proteins...

Thromboelastography (TEG) provides real-time assessment of hemostasis by measuring the viscoelastic properties, coagulation factor, and platelet activity in whole blood samples. In this prospective case-control study, we wanted to investigate whether blood clot formation assessment, using TEG, can identify a hypercoagulable state in women with severe ovarian hyperstimulation syndrome (OHSS). Thirty-six women who were hospitalized with severe OHSS were allocated to the OHSS group and 32 women undergoing controlled ovarian hyperstimulation but who did not develop OHSS were allocated to the control group...

PURPOSE: Ovarian torsion is a surgical emergency that can be clinically challenging to diagnose. Patients who have received assisted reproductive technologies (ART) are a subset of women with an increased risk for torsion. As the ART population continues to increase, there is a need to delineate risk factors for the development of ovarian torsion in this unique population. A pilot study was performed to determine the proportion of patients with suspected ovarian torsion who have received ART and to identify possible diagnostic biomarkers for ovarian torsion among these patients...

Ovarian hyperstimulation syndrome (OHSS) is a serious iatrogenic complication of ovarian stimulation. It is feasible to identify patients at risk, modify stimulation strategies to ameliorate risk, and initiate out-patient treatments that alter disease pathophysiology to reduce disease severity. Mitigation of OHSS risk and severity, through innovative approaches prior to treatment, during treatment and after treatment should now be standard care. This review summarizes recent developments and provides recommendations on the prevention and treatment of OHSS...

BACKGROUND AND PURPOSE: Ovarian hyperstimulation syndrome (OHSS) is a serious complication that occurs after the ovarian-induction treatment. Acute cerebrovascular accident is one of the most dangerous manifestations of the syndrome. However, the characteristics of stroke resulting from OHSS have so far not been well summarised in any study. METHODS: We reported 2 cases of acute cerebrovascular accidents secondary to OHSS. And then we performed a literature search for reports on this type of stroke, and summarised their characteristics...

Previous studies showed that the protein kinase B (Akt)-mammalian target of rapamycin (mTOR) and Hippo signaling-Yes associated protein (YAP) pathways play important roles in promoting follicle growth. Additionally, other studies demonstrated that 5' adenosine monophosphate-activated protein kinase (AMPK) is an upstream regulatory element of mTOR and YAP. Here, we used AMPK inhibitor (Compound C) to in vitro culture ovaries from 10-day-old mice followed by in vivo grafting into adult hosts, or to in situ treat ovaries of 3-week-old mice by intrabursal injection followed by gonadotropin stimulation...

Purpose. To improve success of in vitro fertilization (IVF), assisted reproductive technology (ART) experts addressed four questions. What is optimum oocytes number leading to highest live birth rate (LBR)? Are cohort size and embryo quality correlated? Does gonadotropin type affect oocyte yield? Should "freeze-all" policy be adopted in cycles with progesterone >1.5 ng/mL on day of human chorionic gonadotropin (hCG) administration? Methods. Electronic database search included ten studies on which panel gave opinions for improving current practice in controlled ovarian stimulation for ART...
