Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
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 participants 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 participants in COS cycle 2 are presented.
Participants with observations in both cycles are only counted once.
