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,…
The overall objective of this study is to examine specific cardio-metabolic and cardiovascular parameters in women of subfertile couples. This study protocol is divided in 3 studies to evaluate several cardio-metabolic/cardiovascular parameters in…
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.
To test The Selection Failure hypothesis by assessing A) the degree of embryo invasiveness and decidual acceptance (the quality of decidualization, endometrium-embryo communication and endometrial stromal cell (ESC) migration) and B) the angiogeneic…
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
The present study is designed to validate the Dutch IIEF. The psychometric properties of the Dutch version of the IIEF will be investigated.
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 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.

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)…
