Outcome Measures

Primary Outcomes (1)

  • number of oocytes (COCs)

    obtained during oocyte pick-up (OPU)

    2-4 weeks after after assignment (at oocyte recovery day)

Secondary Outcomes (8)

  • Number of low prognostic patients

    up to 1 week after assignment

  • Duration of stimulation

    2-4 weeks after assignment

  • Number/rate of participants with poor or suboptimal response to COS

    2-4 weeks after after assignment (at oocyte recovery day)

  • Number / rate of mature (MII) oocytes

    2-4 weeks after after assignment (at oocyte recovery day)

  • Fertilization rate

    at day 1 after oocyte recovery

  • +3 more secondary outcomes

Other Outcomes (4)

  • Live birth rate

    up to 3 years after assignment

  • Cumulative live birth rate

    up to 3 years after assignment

  • Cost-effectiveness of COS

    up to 3 years after assignment

  • +1 more other outcomes

Study Arms (2)

antibody positive (CAT+)

OTHER

patients found positive for one of the assayed antichlamydial antibodies

Diagnostic Test: antichlamydial antibody testDrug: treatment of infertility with ART

antibody negative (CAT-)

OTHER

women with negative antichlamydia antibody test

Diagnostic Test: antichlamydial antibody testDrug: treatment of infertility with ART

Interventions

At the first day of stimulation blood analyses for IgG, IgA and IgM (ELISA) to major chlamydial antigens (anti-C.trachomatis), major outer membrane protein (MOMP) and plasmid-encoded protein (pgp3) will be performed for patients found eligible for the study.

antibody negative (CAT-)antibody positive (CAT+)

COS in gonadotropin-releasing hormone (GnRH) antagonist protocol with IVF/ICSI, fresh ET and, if no pregnancy occurred, frozen/thawed ET (for all embryos resulting from this COS) will be performed.

Also known as: Procedure
antibody negative (CAT-)antibody positive (CAT+)
