Freeze-all Policy in Poor Responders

Study Description
Brief Summary:
To compare the effects of fresh embryo transfers (ET) and elective frozen-thawed embryo transfer cycles in poor ovarian responders.

Condition or disease Intervention/treatment Phase
Infertility, Female Other: Freeze-all policy Not Applicable

Study Design
Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 178 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Masking Description: Blinding of the allocated intervention is not possible.
Primary Purpose: Other
Official Title: Fresh Versus Frozen Embryos for Infertility in the Poor Responders as Defined by the Bologna Criteria
Actual Study Start Date : July 30, 2019
Estimated Primary Completion Date : March 1, 2020
Estimated Study Completion Date : December 30, 2020
Arms and Interventions
Arm Intervention/treatment
Experimental: Freeze-all
Good quality embryos (either day 3 or 5) will be frozen and subsequent frozen embryo transfer will be arranged within three months of the egg retrival.
 Other: Freeze-all policy
A policy of freezing all the embryos followed by subsequent thawed frozen embryo transfer
No Intervention: Fresh embryo transfer
Women will undergo fresh embryo transfer at the cleavage (day 3) or blastocyst stage (day 5).
Outcome Measures
Primary Outcome Measures :
  1. Livebirth rate [ Time Frame: 32 weeks ]
    The proportion of women in the population who had at least one live baby.


Secondary Outcome Measures :
  1. Pregnancy rate [ Time Frame: 2 weeks ]
    Positive pregnancy test at two weeks +/- three days after embryo transfer

  2. Clinical pregnancy rate [ Time Frame: 6-8 weeks ]
    The presence of at least one fetal heartbeat at ultrasound between six and eight weeks of gestation
