In this study the investigators compare the traditional way of triggering with a new way in patients with Poly Cystic Ovary Syndrome (PCOS). This to reduce the risque of Ovary Hyper Stimulation Syndrome (OHSS) in In Vitro Fertilization/ IntraCytoplastic Sperm Injection (IVF/ ICSI) treatment. The investigators also compare the number of mature oocytes, embryo's and pregnancy rate.

Condition Intervention Phase
Infertility PCOS Drug: GnRh agonist +1500E hCG Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: No masking
Primary Purpose: Treatment
Official Title: Prospective Randomized Trial on GnRH Agonist Triggering Versus hCG Triggering in IVF Stimulation in PCOS Patients

Further study details as provided by Dr. Decleer Wim, AZ Jan Palfijn Gent:

Primary Outcome Measures:
  • MII oocytes [ Time Frame: patients will be followed during the stimulation with an average of 10 days ]
    The number of mature oocytes retrieved after stimulation without creating OHSS

  • 2 Pro Nuclei (2PN) fertilization [ Time Frame: 24h after ICSI ]
    laboratory follow up of the fertilized egg during the first 24h

Secondary Outcome Measures:
  • implantation rate [ Time Frame: 12 weeks ]
    The number of pregnancies obtained wich still is the most important issue for the patients

  • OHSS [ Time Frame: one month with oocyte retrieval in the middle ]
    patient follow up according to subjective complaints and objective measures

Estimated Enrollment: 120
