Primary Outcome Measures
NameTimeMethod
Percentage of Participants With an Ongoing Pregnancy (Cumulative Ongoing Pregnancy Rate)Up to 1 year after embryo transfer in base trial P05787 (NCT00696800), and FTET cycles in follow up trial

An ongoing pregnancy is the presence of at least one fetus with heart activity at least 10 weeks after embryo transfer or confirmed by live birth.The cumulative ongoing pregnancy rate is 100 times the number of participants with an ongoing pregnancy either immediately after embryo transfer in base Trial P05787 (NCT00696800), or after one or more FTET cycles in follow-up Trial P05716 following cryopreservation, divided by the total number of participants that started treatment in base Trial P05787 (NCT00696800). Participants who did not have cryopreserved embryos, or embryo transfers in the FTET cycle(s), were considered 'not pregnant'.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants in Follow up Trial With a Clinical PregnancyAfter one or more FTET cycles, assessed at least 10 weeks after embryo transfer (up to 1 year)

A clinical pregnancy is the presence of at least gestational sac or confirmed by live birth. Clinical pregnancies were calculated per attempt, meaning if any stage of in vitro fertilization (IVF) treatment was not achieved, zero values were imputed.

Percentage of Participants in Follow up Trial With a Miscarriage Per Vital PregnancyAfter one or more FTET cycles, up to day of miscarriage (up to 1 year)

Miscarriages were calculated per vital pregnancy, meaning the presence of at least one fetus with heart activity.

Percentage of Participants in Follow up Trial With an Ectopic PregnancyAfter one or more FTET cycles, assessed at least 10 weeks after embryo transfer (up to 1 year)

An ectopic pregnancy is where the embryo implants outside the uterus. Ectopic pregnancies were calculated per total number of participants started in FTET.

Percentage of Participants in Follow up Trial With an Ongoing PregnancyAfter one or more FTET, assessed at least 10 weeks after embryo transfer or at live birth (up to 1 year)

An ongoing pregnancy is the presence of at least one fetus with heart activity at least 10 weeks after embryo transfer or confirmed at live birth. Ongoing pregnancies were calculated per attempt, meaning if any stage of IVF treatment was not achieved, zero values were imputed.

Percentage of Participants in Follow up Trial With a Miscarriage Per Clinical PregnancyAfter one or more FTET cycles, up to day of miscarriage (up to 1 year)

Miscarriages were calculated per clinical pregnancy, meaning the presence of at least one gestational sac or confirmed by live birth.

Percentage of Participants in Follow up Trial With a Vital PregnancyAfter one or more FTET cycles, assessed at least 10 weeks after embryo transfer (up to 1 year)

A vital pregnancy is the presence of at least one fetus with heart activity. Vital pregnancies were calculated per attempt, meaning if any stage of IVF treatment was not achieved, zero values were imputed.
