GONAL f® doses starting at minimum of 112.5 IU per day and a maximum of 450 IU per day for 1 cycle only
Other Names:
  • Follitropin alfa
  • Recombinant human follicle stimulating hormone (r-hFSH)
  • GONAL-f® Prefilled Pen
Active Comparator: Standard Dosing
GONAL-f® at a standard dose of 150 IU per day

GONAL f® standard treatment arm (150 IU of GONAL f® per day) up to Day 5 of stimulation after which the dose can be adjusted based upon the subject's ovarian response and according to the center's standard practice.
Other Names:
  • Follitropin alfa
  • r-hFSH
  • GONAL-f® Prefilled Pen

Primary Outcome Measures :
  1. Number of Oocytes Retrieved Per Participant [ Time Frame: 34-38 hours post-recombinant human choriogonadotropin (hCG) (OPU) ]
    Mean number of oocytes retrieved on the day of ovum pick up (OPU) was calculated. Oocyte retrieval is a technique used in in-vitro fertilization in order to remove oocytes from the ovary of the female, enabling fertilization outside the body.

Secondary Outcome Measures :
  1. Total GONAL-f® Dose [ Time Frame: Start of treatment until end of stimulation cycle (approximately 28 days) ]
  2. Mean GONAL-f® Daily Dose [ Time Frame: Start of treatment until end of stimulation cycle (approximately 28 days) ]
  3. Total Number of GONAL-f® Stimulation Treatment Days [ Time Frame: Start of treatment until end of stimulation cycle (approximately 28 days) ]
  4. Number of Participants With Cancelled Cycles Due to Excessive or Inadequate Response to Treatment [ Time Frame: Start of treatment until Day 15-20 post-hCG ]
    Number of participants with cancelled cycles due to excessive or inadequate response was evaluated. An excessive response: greater than or equal to 25 oocytes which could put the participant at risk of OHSS; An inadequate response: defined as 3 or less follicles of greater than or equal to 12 millimeter (mm) developing following at least 7 days of GONAL-f® treatment.

  5. Percentage of Participants With Biochemical Pregnancies [ Time Frame: Start of treatment until Day 15-20 Post-hCG ]
    Biochemical pregnancy was defined as a pregnancy diagnosed only by the detection of hCG in serum and that does not develop into a clinical pregnancy.

  6. Number of Participants With Fetal Sacs and Fetal Hearts [ Time Frame: Day 35-42 Post-hCG ]
    Number of participants with fetal sacs and fetal hearts (with activity) as seen on an ultrasound scan to confirm clinical pregnancy.

  7. Implantation Rate [ Time Frame: Day 35-42 Post-hCG ]
    Implantation rate was measured as the number of gestational sacs observed divided by the number of embryos transferred multiplied by 100.

  8. Number of Participants With Multiple Pregnancies [ Time Frame: Day 35-42 Post-hCG ]
    Multiple pregnancy was defined as 2 or more fetal hearts with activity.

  9. Serum Progesterone (P4) Levels [ Time Frame: End of stimulation cycle (approximately 28 days) ]
  10. Percentage of Participants With Clinical Pregnancy [ Time Frame: Day 35-42 Post-hCG ]
    Clinical pregnancy is defined by the number of sacs and hearts with activity per ultrasound scan performed on Day 35-42 post-hCG.

  11. Number of Participants With OHSS [ Time Frame: Start of treatment until Day 15-20 Post-hCG ]
    OHSS is a syndrome which can manifest with enlarged ovaries, advanced ascites with increased vascular permeability, pleural fluid accumulation, hemoconcentration, and increased blood clotting.

  12. Pregnancy Outcome - Number of Participants With Pregnancy and Their Outcome [ Time Frame: up to 9 month (following the end of treatment) ]
    Pregnancy outcomes are live outcome (live infant) and non-live outcome (non-live infant) or unknown outcome (subject lost to follow-up).
