- Proportion (Percentage) of Subjects With Treatment-induced Anti-Follicle-Stimulating Hormone (FSH) Antibodies After up to Two Repeated Controlled Ovarian Stimulation Cycles [ Time Frame: Stimulation day 1, 7-10 days after last FE 999049 or GONAL-F dose and 21-28 days after last FE 999049 or GONAL-F dose ]The proportion (percentage) of subjects with at least one treatment-induced anti-FSH antibody response at any time point is presented. The cumulative incidences in COS cycle 2 and COS cycle 3 divided by subjects in COS cycle 2 are presented. Subjects with observations in both cycles are only counted once.
- Proportion (Percentage) of Subjects With Treatment-induced Anti-FSH Antibodies With Neutralising Capacity After up to Two Repeated Controlled Ovarian Stimulation Cycles [ Time Frame: Stimulation day 1, 7-10 days after last FE 999049 or GONAL-F dose and 21-28 days after last FE 999049 or GONAL-F dose ]The proportion (percentage) of subjects with treatment-induced anti-FSH antibodies with neutralising capacity at any time point is presented. The cumulative incidences in COS cycle 2 and COS cycle 3 divided by subjects in COS cycle 2 are presented. Subjects with observations in both cycles are only counted once.
- Proportion (Percentage) of Subjects With Treatment-induced Anti-FSH Antibodies, Overall as Well as With Neutralising Capacity, After One and After Two Repeated Controlled Ovarian Stimulation Cycles [ Time Frame: Stimulation day 1, 7-10 days after last FE 999049 or GONAL-F dose and 21-28 days after last FE 999049 or GONAL-F dose ]The proportion (percentage) of subjects with treatment-induced anti-FSH antibodies, overall as well as with neutralising capacity, after one and after two repeated COS cycles is presented.
- Proportion (Percentage) of Subjects With Early Ovarian Hyperstimulation Syndrome (OHSS) (Including OHSS of Moderate/Severe Grade) and/or Preventive Interventions for Early OHSS for Each Controlled Ovarian Stimulation Cycle [ Time Frame: ≤9 days after triggering of final follicular maturation. ]The proportion (percentage) of subjects with early OHSS, early OHSS of moderate or severe grade, preventive interventions for early OHSS, early OHSS and/or preventive interventions for early OHSS, and early OHSS of moderate or severe grade and/or preventive interventions for early OHSS are presented.
- Proportion (Percentage) of Subject With Cycle Cancellation Due to Poor Ovarian Response or Excessive Ovarian Response for Each Controlled Ovarian Stimulation Cycle [ Time Frame: End-of-stimulation (up to 20 stimulation days) ]Proportion (percentage) of subjects with cycle cancellation due to poor ovarian response, excessive ovarian response, and triggering with gonadotropin-releasing hormone (GnRH) agonist are presented.
- Vital Pregnancy Rate for Each Controlled Ovarian Stimulation Cycle [ Time Frame: 5-6 weeks after blastocyst transfer ]Vital pregnancy was defined as at least one intrauterine gestational sac with fetal heart beat 5-6 weeks after blastocyst transfer.
- Implantation Rate for Each Controlled Ovarian Stimulation Cycle [ Time Frame: 5-6 weeks after blastocyst transfer ]Implantation rate was defined as the number of gestational sacs 5-6 weeks after transfer divided by number of blastocysts transferred.
- Ongoing Pregnancy Rate for Each Controlled Ovarian Stimulation Cycle [ Time Frame: 10-11 weeks after blastocyst transfer ]Ongoing pregnancy rate was defined as at least one intrauterine viable fetus 10-11 weeks after blastocyst transfer.
- Ongoing Implantation Rate for Each Controlled Ovarian Stimulation Cycle [ Time Frame: 10-11 weeks after blastocyst transfer ]Ongoing implantation rate was defined as the number of intrauterine viable fetuses 10-11 weeks after transfer divided by number of blastocysts transferred.
- Frequency of Injection Site Reactions (Redness, Pain, Itching, Swelling and Bruising) Assessed by the Subject During the Stimulation Period for Each Controlled Ovarian Stimulation Cycle [ Time Frame: End-of-stimulation (up to 20 stimulation days) ]Subjects self-assessed injection site reactions (redness, itching, pain, swelling and bruising) immediately, 30 minutes and 24 hours after each injection. The injection site reactions were assessed as none, mild, moderate and severe. The frequency of injection site reactions (mild, moderate or severe) based on all assessment performed is presented.
- Proportion (Percentage) of Subjects With Late OHSS (Including OHSS of Moderate/Severe Grade) for Each Controlled Ovarian Stimulation Cycle [ Time Frame: >9 days after triggering of final follicular maturation ]Late OHSS was defined as OHSS with onset >9 days after triggering of final follicular maturation.
- Technical Malfunctions of the Administration Pen for Each Controlled Ovarian Stimulation Cycle [ Time Frame: End-of-stimulation (up to 20 stimulation days) ]Incidences of confirmed technical malfunction of administration pen are presented.
