Study questionAre previously proposed vaginal microbial community state types (CSTs) valid predictors of IVF success, or do alternative microbial signatures provide stronger associations?Summary answerPreviously proposed CSTs as predictors …

Study questionHow should recurrent implantation failure (RIF) in patients undergoing ART be defined and managed?Summary answerThis is the first ESHRE good practice recommendations paper providing a definition for RIF together with recommend…

Study questionIs it possible to define a set of performance indicators (PIs) for clinical work in ART, which can create competency profiles for clinicians and for specific clinical process steps?Summary answerThe current paper recommends si…

Study questionCan consensus definitions for the core outcome set for infertility be identified in order to recommend a standardized approach to reporting?Summary answerConsensus definitions for individual core outcomes, contextual statement…

Study questionWhat is the independent contribution of endometrial thickness (EMT) on day of embryo transfer to achieving an ongoing pregnancy and live birth after IVF treatment?Summary answerEMT is a poor predictor of IVF success and has on…

Tubal factor infertility (TFI) accounts for more than 30% of the cases of female infertility and mostly resides from an inflammatory process triggered by an infection. Clinical appearances largely differ, and very often infections are not r…

Introduction: Does the endometrial thickness (EMT) at the time of follicle aspiration correlate with the pregnancy rate in unstimulated menstrual cycles? Materials and Methods: This is a retrospective, observational single center study.105 …

ObjectiveTo summarize efficacy and safety data on a new progesterone compound which is available for subcutaneous administration as compared to vaginally administered progesterone for luteal phase support in patients undergoing IVF treatmen…

BackgroundHuman chorionic gonadotropin (HCG) is routinely used for final oocyte maturation triggering in in vitro fertilisation (IVF)/intracytoplasmic sperm injection (ICSI) cycles, but the use of HCG for this purpose may have drawbacks. Go…

PURPOSE: In the GnRH-antagonist protocol, ovarian stimulation with gonadotropins typically commences on cycle day 2 or 3. Initiation of ovarian stimulation with a spontaneously occurring menstruation, however, poses significant organization…

BACKGROUND: Although transvaginal ultrasound-guided oocyte retrievals (OR) are performed routinely worldwide, there is very little systematic data about its complications. METHODS: We performed a prospective cohort study following the perio…

Ovarian hyperstimulation syndrome (OHSS) is a severe complication of ovarian stimulation. No reliable test exists to predict the syndrome. The objective of the present prospective observational study was to examine vascular endothelial grow…

Suppression of sex steroid production based on desensitisation and down-regulation of pituitary gonadotropin-releasing hormone (GnRH)-receptors by agonistic GnRH-analogues resulting in the blockage of gonadotropin release from the anterior …

Gonadotropin-releasing hormone (GnRH) stimulates the pituitary secretion of both luteinising hormone (LH) and follicle-stimulating hormone (FSH), and thus controls the hormonal and reproductive functions of the gonads. The blockade of the e…
