Previous studies indicated that progesterone can be withdrawn at the time of the first positive β-hCG test without compromising the clinical pregnancy outcome in normal ovarian responder. However, the effect of early stop of progesterone supplementation for patients with poor ovarian response (POR) has not been investigated. This study retrospectively collected data from patients with POR in 156 IVF/ICSI fresh embryo transfer (ET) cycles in single tertiary center from January 2010 to June 2016. All the patients met ESHRE consensus, the Bologna criteria, of POR and had hCG injection for luteal phase support (LPS) on day 2, 5 and 8 after ovum pick-up...

Our In-Vitro Fertilisation Centre is situated in a large developing country, Madagascar, with very bad roads and low income patients. Therefore we try to find ways to reduce as much as possible the number of attempts to obtain a pregnancy. Poor or no response to ovarian stimulation in In Vitro Fertilization (IVF) cycles is a great challenge. Here we describe a method whereby we shift from IVF to Oocyte Donation (OD) during the same cycle for patients whose ovaries do not respond properly to ovulation stimulation...

STUDY QUESTION: Is the length of the anogenital distance (AGD) a biomarker of ovarian reserve and response to controlled ovarian stimulation (COS)? SUMMARY ANSWER: Shorter AGD is associated with presence of poor ovarian response. WHAT IS KNOWN ALREADY: Organ development during prenatal life is influenced by the prevailing intrauterine environment, and it has been suggested that nutritional, environmental and toxic factors could affect ovarian reserve set prenatally...

STUDY QUESTION: Do infertile women aged <38 years with quantitative evidence of diminished ovarian reserve and/or poor response to stimulation also exhibit poor oocyte quality as measured by blastulation rates, aneuploidy rates, and live birth rates? SUMMARY ANSWER: Young women with evidence of accelerated follicular depletion, either by precycle ovarian reserve testing or postcycle evidence of low oocyte yield, exhibit equivalent blastulation rates, aneuploidy rates and live birth rates per euploid embryo transfer as age-matched controls with normal precycle and postcycle parameters...

BACKGROUND: Fragile-X-Mental-Retardation-1- (FMR1)-gene is supposed to be a key gene for ovarian reserve and folliculogenesis. It contains in its 5'-UTR a triplet-base-repeat (CGG), that varies between 26 and 34 in general population. CGG-repeat-lengths with 55-200 repeats (pre-mutation = PM) show instable heredity with a tendency to increase and are associated with premature-ovarian-insufficiency or failure (POI/POF) in about 20%. FMR1-mRNA-expression in leucocytes and granulosa cells (GCs) increases with CGG-repeat-length in PM-carriers, but variable FMR1-expression profiles were also described in women with POI without PM-FMR1 repeat-length...

Background Aurora kinase overexpression or amplifications are associated with high proliferation, poor prognosis, and therapeutic resistance in human tumors. AMG 900 is an investigational, oral, selective pan-Aurora kinase inhibitor. Methods This first-in-human trial included dose-escalation and dose-expansion phases ( ClinicalTrials.gov : NCT00858377). Dose escalation evaluated the safety, tolerability, and pharmacokinetics of AMG 900 in advanced solid tumors and determined the maximum tolerated dose (MTD) with/without granulocyte colony-stimulating factor (G-CSF) prophylaxis...

RATIONALE: Ovarian malignancy is associated with one of the highest rates of death among gynecological reproductive system malignancies. While progress has been made in surgical and postoperative adjuvant treatment approaches, the early atypical clinical manifestations, quick progression, and lack of the effective early screening means imply that the prognosis remains poor. Bilateral ovarian cancers are common, but different types of primary bilateral ovarian carcinomas are extremely rare...

BACKGROUND: Arylamine N-acetyltransferase 1 (NAT1) is a drug metabolizing enzyme that has been associated with cancer cell proliferation in vitro and with survival in vivo. NAT1 expression has been associated with the estrogen receptor and it has been proposed as a prognostic marker for estrogen receptor positive cancers. However, little is known about the distribution of NAT1 mRNA across an entire patient population or its effects on outcomes. To address this, gene expression data from breast cancer patient cohorts were investigated to identify sub-populations based on the level of NAT1 expression...

A panel of experts known as the POSEIDON group has recently redefined the spectrum of poor responder patients and introduced the concept of suboptimal response. Since an ideal management for these patients is still missing, they highlighted the importance of tailoring the ovarian stimulation based on the chance of each woman to obtain an euploid blastocyst. Interestingly, a novel pattern of follicle recruitment has been defined: multiple waves may arise during a single ovarian cycle. This evidence opened important clinical implications for the treatment of poor responders...

INTRODUCTION: Luteal phase ovarian stimulation (LPOS) has been proven a feasible protocol for infertile patients. High progesterone level in the luteal phase could physiologically inhibit premature luteinizing hormone surge, from which poor ovarian responders (PORs) could obtain benefits. Therefore, we aimed to compare clinical outcomes between LPOS and follicular phase ovarian stimulation (FPOS) protocol in PORs undergoing in vitro fertilization (IVF). METHODS: This prospective pilot study was performed at one tertiary center from January 2016 to October 2017...

BACKGROUND: Previous studies have shown that androgens, in addition to serving as precursors for ovarian estrogen synthesis, also have a fundamental role in primate ovarian follicular development by augmentation of FSH receptor expression on granulosa cells. Recent studies have shown that aromatase inhibitor, letrozole, improves ovarian response to FSH in normal and poor responder patients, possibly by increasing intraovarian androgen levels. Studies in mice also showed an effect of letrozole to increase pigment epithelium-derived factor (PEDF) and to lower vascular epithelial growth factor (VEGF), which might be expected to reduce the risk of ovarian hyperstimulation syndrome (OHSS) with stimulation...

RESEARCH QUESTION: A number of live-birth predictive models are available, and despite clinical interest these are rarely used owing to poor performance. In addition, no predictive models specifically for poor ovarian responders (POR) are available. The aim of the current project was to develop a clinically applicable tool for predicting live birth for PORs receiving recombinant human FSH [r-hFSH]. DESIGN: A model was developed to predict live birth in PORs receiving r-hFSH, using data from the ESPART trial...

BACKGROUND: The use of long protocol during controlled ovarian stimulation for assisted reproduction attracts high dosage of gonadotropins. High dose of gonadotropins can be detrimental to oocyte development, which affects its quality and compromises the treatment outcome. Mild stimulation protocols that attract low dose gonadotropins could be useful alternative regimen to address such problems. This study evaluated the efficacy of low dose clomiphene citrate based protocol plus low dose gonadotropins on predicted normal responder patients who had unsuspected poor in vitro fertilization (IVF) result, following an initial stimulation with long gonadotropin-releasing hormone (GnRH) agonist protocol...
