The primary endpoint was the proportion of patients who achieved monofollicular or bifollicular development (defined as one or two follicles 15 mm). Secondary endpoints included characteristics of ovulation stimulation treatment, such as mean total and mean daily r-hFSH doses. Data were analyzed for 3,193 patients from 30 German fertility centers. The proportion of patients with monofollicular or bifollicular development was 71.1% (n=2,270 of a total of 3,193 patients; intent-to-treat population). The mean±standard deviation total and daily doses of r-hFSH were 696.9±542.5 IU and 61.7±29.4 IU, respectively. The three doses prescribed most frequently were: 37.5 IU (n=703 from N=3,189; 22.0%), 50.0 IU (n=1,056 from N=3,189; 33.1%), and 75.0 IU (n=738 from N=3,189; 23.1%) on the first day of stimulation; and 37.5 IU (n=465 from N=3,189; 14.6%), 50.0 IU (n=922 from N=3,189; 28.9%), and 75.0 IU (n=895 from N=3,189; 28.1%) on the last day of stimulation. This noninterventional, post-marketing surveillance study found that monofollicular or bifollicular development was achieved in 71% of patients studied and the small dose increment (12.5 IU) of the redesigned follitropin alfa pen allowed individualized treatment of women undergoing OI.
