To evaluate the effects of withholding progesterone-induced endometrial withdrawal bleeding before ovulation induction on the time to pregnancy and the ongoing pregnancy rate.
In view of this lack of evidence and strong practice variation we propose a randomized clinical trial in overweight and obese subfertile women, in which we compare the costs and effects of a six months structured lifestyle program, aimed at weight…
Investigate whether the "Smarter Pregnant" intervention in comparison with four screenings with food- and lifestyle advising leads to an improvement in unhealthy food habits (vegetables, fruit, folic acid use) after 24 weeks intervention,…
In one third of subfertile couples male subfertility is diagnosed. Current treatments for male subfertility, IUI, IVF and ICSI, have,despite their widespread use, not been compared on their cost-effectiveness. The primary aim of this project is to…
Objectives: The purpose of this study is to assess the costs and effects of THL compared to HSG in a large randomized controlled trial.
The main objective of this open-label, randomized clinical trial is to asses whether patient-controlled analgesia with remifentanil is more efficious and equally safe as pethidine as analgesic strategy during ultrasound-guided transvaginal oocyte…
To determine wether a HyFoSy is a less painful procedure compared to a HSG examination for tubal patency testing
To compare live birth rates among patients receiving cryo thawed embryo transfer after endometrial preparation with estrogen/progesterone substitution and patients receiving cryo thawed embryo transfer in a natural cycle.
To evaluate the course of psychological emotions, from the active treatment period until the first pregnancy test result, in IVF patients participating in a randomized controlled trial comparing two different IVF treatments (ENDO-RECEPT).
To demonstrate whether an early fixed start antagonist protocol improves the live birth rate compared with a late fixed start antagonist protocol.
To compare the cumulative ongoing pregnancy rate after transfer of frozen/thawed embryos in a cycle without ovarian hyperstimulation with transfer of fresh embryos in a cycle with ovarian hyperstimulation.
To evaluate the effect of 15 minutes of immobilisation after IUI on the pregnancy rate
The effect of rLH for controlled ovarian hyperstimulation in order to achieve an increase of 10% in top quality embryos.
To determine whether flushing of the fallopian tubes is more effective with an oil based contrast medium or a water based contrast medium in terms of ongoing pregnancy.
The objective of this study is to evaluate a new and less invasive method of PGS. The new PGS technique will analyse a nucleus of a blastomere that was obtained by nuclear extraction rather than by biopsy of a whole blastomere.
1. To prevent multiple pregnancies and the concomittant neonatal mortality and morbidity while retaining acceptable delivery rates in couples with unexplained subfertility or mild male subfertility and poor fertility prospects. 2. To assess the…
The aim of the study is to determine whether cycle day (CD) 5 start of stimulation will lead to better quality of embryos, based on morphology, than CD 2 start, in IVF with GnRH antagonist co-treatment started on a fixed day.
The aim of the study is to show non-inferiority of a short, flare-up GnRH-agonist protocol to the GnRH-antagonist protocol, both with OC pill pre-treatment, in women undergoing in vitro fertilisation (IVF) or intracellular sperm injection (ICSI)…
Primary objective: To evaluate the cumulative live birth rate for two treatment strategies: 2 IVM/ICSI cycles versus 1 COH/IVF or COH/ICSI cycle.Secondary Objectives: To evaluate the health and development of IVM/ICSI children versus COH/IVF/ICSI…
The purpose of this study is to assess the effectiveness of extended treatment with CC compared to treatment with gonadotropins and/or the use of intra-uterine insemination, in patients who had six ovulatory cycles after CC, but did not conceive.
