What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cumulative pregnancy rate

    Measured: at 12 months of fresh embryo transfer (time considered enough in order to do a minimum of one frozen-thawed cycle if pregnancy is not achieved with the fresh cycle

Secondary outcomes (3)
  1. Cumulative live birth rate

  2. Multiple pregnancy rate

  3. Time needed to achieve the pregnancy

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted26 Oct 2010 (estimated)
  2. Study startOct 2010
  3. Primary completionDec 2012
  4. Study completionDec 2012

Why it stopped: Due to the high number of multiples pregnancies in the double embryo transfer group, we have decided to stop the enrollment of patients at 07/31/2012
