The developmental and implantation potential of aneuploid and mosaic human embryos, as assessed in an in vitro model

To increase our understanding of the developmental significance of chromosomal mosaicism in preimplantation embryos by investigating their implantation potential and the fate of abnormal cells after an in vitro implantation procedure.

A study of the effects of a novel ovarian stimulation regimen on embryo aneuploidy rates in IVF, and the impact of aneuploidy on implantation, as assessed in an in vitro model.

In this study we aim to compare the effect of two different ovarian stimulation protocols on embryo quality in a group of women of 39 years or younger, in a prospectively randomized controlled trial. PGS will be performed to assess chromosomal…

symptoms and/or erectile dysfunction who show up at the OPD urology of the VU medical center with a lack of
physical activity.

1. determine how many male patients visiting the OPD urology for LUTS and/ or ED lack a certain amount of physical activity2. measure the willingness of those patients to follow a program for increasing their physical activity3. discover factors…

SIMULTANEOUS MEASUREMENT OF PELVIC FLOOR ACTIVITY, VAGINAL PLETHYSMOGRAPHY AND VAGINAL INNERVATION IN WOMEN WITH AND WITHOUT HYPERACTIVE PELVIC FLOOR SYNDROME.

The purpose of this study is to investigate whether the hyperactive pelvic floor syndrome can be assessed by objective measurement. This will be done by means of a newly developed instrument, the so-called VPA/EMG/sensibility-combiprobe, that…

Towards a new technique for pre-implantation genetic embryo screening in IVF, pilot phase

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.

Prevention of multiple pregnancies in couples with unexplained or mild male subfertility.

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…

Pilot study: A comparison of the gold standard for measuring genital blood flow in humans with infrared thermal imaging as sex-neutral measurement

To compare the present gold standard for measuring genital blood flow in humans (for men: a mechanical penile strain gauge (Barlow-gauge) , for women: vaginal photoplethysmography) with infrared technology.

DOse volume effects and Fibrosis in the corpora cavernosa After Radiotherapy for prostate cancer
A pilot study

The first objective of this study is to test the hypothesis that a higher dose to the IPAs and corpora cavernosa is correlated to ED after EBRT. The second objective is to test the hypothesis that RIF in the IPAs and corpora cavernosa is correlated…

Predictors of psychological distress in couples undergoing infertility treatment.

It is important that we get insight into which of the above mentioned factors are related to psychological problems. It could give us some important starting points for designing psychological intervention programs. Such an intervention could not…
