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.

Condition Intervention
Multifollicular Stimulation
Drug: Recombinant-follicle stimulating hormone (r-FSH)

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: 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

Further study details as provided by Merck KGaA:

Primary Outcome Measures:
  • 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

Enrollment: 25
Study Start Date: February 2009
Study Completion Date: February 2010
Primary Completion Date: February 2010 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Recombinant-follicle stimulating hormone (r-FSH)

    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).

Study Population
Female subjects, who are being considered for an IVF/ICSI treatment and a Gonal-f treatment based on the PFS and inclusion and exclusion criteria will be eligible for the study.

Inclusion Criteria:

  • Female subjects who started treatment with Gonal-f on the basis of the decision of the investigator and indications and recommendations of the PFS
  • Subjects who were at least 35 years old when the Gonal-f dose was administered (i.e. at the time of introducing individual variables of the subject in the CONSORT calculator for determining the dose)
  • Subjects with BMI < 30 kg/m2
  • Subjects who were in premature follicle phase (day 2-4), basal FSH ≤12 IU/l (measured in the center's laboratory)
  • Subjects who were taking a gonadotropin-releasing hormone (GnRH) protocol agonist
  • Subjects who consented to participate in the study and inform the investigator about their medical history
  • Subjects who signed the written consent form, which stipulated that the subject could dropout of the study at any time without any negative consequences on future medical treatments

Exclusion Criteria:

  • Subjects simultaneously participating in an interventional study
  • Subjects following concomitant treatment with clomifene citrate
  • Subjects presenting one of the contraindications described in the SPC
