This is a prospective, observational and multicentric study to compare the Gonal-f FbM (filled by mass) dose prescribed by the doctor with the Gonal-f FbM dose determined by the CONSORT (Consistency in r-FSH Starting doses for individualized treatment) calculator.
A Prospective, Observational and Multicentric Study to Compare the Dose of GONAL-fTM FbM Prescribed by the Doctor With the Recommendation of the Dose Calculator Consort and to Evaluate the Ease of Use of Pre-filled Pen of GONAL-fTM FbM Pen
The dosage and administration of r-FSH will be in accordance with the PFS and current clinical practice in the centers (300 IU/0.5 ml [22 micrograms/0.5 ml]; 450 IU/0.75 ml [33 micrograms/0.75 ml]; or 900 IU/1.5 ml [66 micrograms/1.5 ml].
The dosage and administration of recombinant-hCG (r-hCG; 250 micrograms/0.5 ml), injectable solution in a pre-filled syringe will also be in accordance with the PFS and current clinical practice in the centers (only if the doctor decides to start treatment with r-hCG).
Comparison between the initial Gonal-f FbM dose prescribed by the doctor and the initial Gonal-f FbM dose recommended by the CONSORT calculator [ Time Frame: Before and after the treatement for 1 cycle over a period of 6 months ]
Secondary Outcome Measures
Secondary variables [ Time Frame: Before and after the treatement for 1 cycle over a period of 6 months ]
Total Gonal-f dose used; subject satisfaction; duration of the treatment; Gonal-f dose used on the last day of stimulation; total dose of gonadotropins used; number of cases of ovarian hyper-stimulation syndrome (OHSS); number of cancelled cycles; number of clinical pregnancies; incidence and seriousness of OHSS
