Outcome Measures

Primary Outcomes (1)

  • Cumulative Ongoing pregnancy rate

    calculated by the number of ongoing pregnancy patients divided by the total number of patients in appropriate group

    week 11 - 14 of pregnancy

Secondary Outcomes (6)

  • Pregnancy rate

    2 weeks after embryo transfer

  • Ongoing pregnancy rate

    week 11 - 14 of pregnancy

  • Number of oocytes retrieved

    4 hours after occyte pick-up

  • Number of mature oocytes

    4 hours after oocyte pick-up

  • Number of competent embryos

    3 days to 5 days after oocyte pick-up

  • +1 more secondary outcomes

Study Arms (2)

Study

EXPERIMENTAL
