In this study the investigators compare the traditional way of triggering with a new way in PCOS patients. This to reduce the risque of OHSS in IVF/ ICSI treatment. The investigators also compare the number of oocytes, embryo's and pregnancy rate.

Primary Outcome Measures:
  • M2 oocytes [ Time Frame: patients will be followed during the stimulation with an average of 10 days ] [ Designated as safety issue: No ]
    The number of mature oocytes retrieved after stimulation without creating OHSS

  • 2PN fertilization [ Time Frame: 24h after ICSI ] [ Designated as safety issue: No ]
    laboratory follow up of the fertilized egg during the first 24h

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

Secondary Outcome Measures:
  • implantation rate [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    The number of pregnancies obtained wich still is the most important issue for the patients

Estimated Enrollment: 120
