Brief Summary:
In this study of endometriosis patients we compare a common treatment of surgical therapy and medical treatment for 3 months (Zoladex) with patients receiving only surgical therapy. In both cases they immediately start In Vitro Fertilization (IVF) treatment.

Condition or disease Intervention/treatment Phase
Infertility Endometriosis Drug: Zoladex Phase 4

Arm Intervention/treatment
Active Comparator: Zoladex
After surgical vaporization of endometriosis patients are treated with Zoladex for 3 months.
Drug: Zoladex
after surgical vaporization patients are treated with Zoladex for 3 months before starting IVF treatment

No Intervention: vaporization only
Surgical vaporization of the endometriosis is done and patients start IVF without additional treatment.

Primary Outcome Measures :
  1. Number of Metaphase II Cells (MII) [ Time Frame: 3 weeks ]
    number of MII cells retrieved

Secondary Outcome Measures :
  1. Pregnancy Rate [ Time Frame: 12 weeks ]
    The number of ongoing pregnancies obtained which still is the most important issue for the patients.

  2. Good Embryo Quality [ Time Frame: 3 days after oocyte retrieval ]
    The development of the embryo at the time of transfer on day 3. Good quality is defined by more than 7 cells and less then 20% fragmentation on day 3.

  3. Number of Pro Nuclear Cell (2PN) [ Time Frame: 1 day after oocyte retrieval ]
    number of 2PN

  4. Number of Cryopreserved Embryos [ Time Frame: 1 week after oocyte retrieval ]
    number of blastocytes that can be cryopreserved

  5. Total Follicle Stimulating Hormone (FSH) Dose [ Time Frame: 3 weeks ]
    total dose of FSH needed at the end of stimulation

Other Outcome Measures:
  1. Number of Days of Stimulation [ Time Frame: 3 weeks ]
    number of days needed before follicles in the ovary are mature for oocyte retrieval
