Prospective, multicenter, randomized controlled trial towards identifying the optimal Cetrotide treatment protocol

To demonstrate whether an early fixed start antagonist protocol improves the live birth rate compared with a late fixed start antagonist protocol.

A phase II, multicentre, randomised, assessor blinded, active-comparator, parallel-group dose finding trial to evaluate AS900672-Enriched versus follitropin alfa (GONAL-f) in oligo-anovulatory infertile women undergoing ovulation induction (OI)

Primary objectiveThe primary objective of this trial is to identify the optimal effective dose of AS900672-Enriched to induce ovulation in oligo-anovulatory infertile women.Secondary objectives* To demonstrate that the clinical pregnancy rate of the…

In vitro maturation of human oocytes with subsequent IVF or ICSI . An observational study with follow up of the children.

The objective of this observational study is the safe introduction of clinical applied IVM in The Netherlands. During this study, the number and quality of the oocytes and embryos will be studied as well as pregnancy development. Emphasis will be on…

FSH receptor polymorphisms and treatment of poor responders

The hypothesis is that women who have the Ser680Ser (SS) variant of the FSH receptor genotype, in comparison with women with the Ser680Asn (NS) or Asn680Asn (NN) variant, are less sensitive to FSH and because of that need higher dosages of FSH when…

The effect on embryo-quality of rLH-addition to rFSH for controlled ovarian hyperstimulation in women with poor ovarian reserve

The effect of rLH for controlled ovarian hyperstimulation in order to achieve an increase of 10% in top quality embryos.

Among IVF patients undergoing fixed antagonist protocols with recombinant FSH, does administration of recombinant FSH from cycle day 5 onwards compared with cycle day 2 onwards, yield a higher number of good quality embryos?

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.

TREATMENT ALTERNATIVES FOR SUBFERTILE WOMEN WITH CLASS II ANOVULATION NOT CONCEIVING AFTER SIX OVULATORY CYCLES WITH CLOMIPHENE CITRATE

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.

A phase IV prospective, multicentre, randomized, open-label trial to assess the efficacy and safety of GONAL f® at a dose based on subject baseline characteristics determined according to the CONSORT calculator compared with a standard dose of GONAL f® 150 IU per day for ovarian stimulation in women undergoing assisted reproductive technology (ART)

The purpose of this trial is to compare the ovarian response in assisted reproductive technology (ART) subjects administered a GONAL-f® dose determined according to a calculator system versus a given standard GONAL-f® dose of 150 International Unit…
