Filter by:Background: The number of multiple pregnancies is considered to be the most important adverse effect of in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI). IVF or ICSI with transferring only one embryo, elective single embryo transfer (eSET), will reduce this incidence remarkably. Unfortunately, former research has documented that cycles with SET maintain lower pregnancy rates compared to double embryo transfer (DET). Implementation of eSET will require a carefully chosen and thoroughly defined implementation strategy focussed on the couple undergoing the subfertility treatment. This trial will investigate the (cost)effectiveness of a combined patient centred implementation strategy. Objective: The main aim is to compare the effectiveness and costs of implementation of elective single embryo transfer (eSET) in in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI), between usual care and a combined patient-centred strategy. Study design: A randomised controlled trial Study population: Couples with a female age less than 40 years ongoing an IVF/ICSI treatment in 2 of the 13 Dutch IVF centres and their 4 satellite/transport centres. Intervention A combined patient centred implementation strategy for eSET in IVF/ICSI. The strategy consists of counselling through an evidence based decision aid and reimbursement of a 4th cycle if couples have chosen for eSET in the first 2 cycles. Primary study parameters/outcome of the study: the eSET occurrence rate, pregnancy outcomes and cost-effectiveness of the combined strategy. Secondary study parameters/outcome of the study: - patient knowledge - patient decisional conflict - patient satisfaction - IVF/ICSI treatment outcome.
The overall hypothesis to be tested is: women with the molecular phenotype of highly skewed X chromosome inactivation are at increased risk of spontaneous abortion.
This study will be performed in approximately 132 women with anovulatory/oligoovulatory infertility.
We want to investigate if early follicular phase downregulation and androgen priming, by use of GnRH antagonist, aromatase inhibitor and hCG before COH in a short protocol, shows signs of improvement compared to standard short antagonist protocol
Implantation failure of the embryo might be the result from the environment in the uterus. Proteins (cytokines) are screted by the endometrium which can result in a pro or anti inflammatory environment. The aim of this study is to identify pre-implantation endometrial and embryo cytokine expression profiles associated with successful and unsuccessful embryo implantation in assisted reproduction cycles.
The purpose of this experiment is to investigate whether the dependence of luteinizing hormone pulsatility on energy availability declines during adolescence.
The purpose of this randomized prospective clinical trial is to determine whether an infertility treatment that moves quickly to In Vitro Fertilization (IVF) is more cost effective than the usual treatment strategy which includes various combinations of infertility drugs and intrauterine insemination (IUI) prior to utilizing In Vitro Fertilization.
Prospective open label, randomised, parallel group, comparative pilot.
Clinical validation of the assisted reproductive technology (ART) treatment guidelines, which determine the optimal dose of recombinant human follicle stimulating hormone (r-hFSH) based on subject baseline characteristics/predictors of ovarian response.
The purpose of this study is to evaluate the effectiveness of the OV-Watch to predict ovulation while women are taking clomiphene citrate.
