    9 -20 days from initiation of ovarian stimulation

  • Total additional dose of rFSH (IU)

    9 -20 days from initiation of ovarian stimulation

  • Duration of ovarian stimulation

    9 -20 days from initiation of ovarian stimulation

  • Endocrine profile at specific intervals

    Stimulation day 1, day 6, day 8, and Day of final oocyte maturation (actual day may vary between 9-15)

  • +1 more secondary outcomes

Study Arms (2)

Early follicular phase protocol

ACTIVE COMPARATOR

On day 2 or 3 of the menstrual cycle, following baseline blood sampling, a single SC injection of 150 ìg corifollitropin alfa will be administered (Stimulation Day 1). Starting on Stimulation Day 6, the subject will receive a daily SC injection of 0.25 mg ganirelix up to and including the day of GnRH agonist triggering administration to prevent premature LH surges. From Stimulation Day 8 onwards treatment is continued with a daily SC dose of rFSH (200IU/day) up to the day of GnRHa administration.

Drug: Follicular phase corifollitropin alfa

Luteal phase protocol

EXPERIMENTAL

Following baseline blood sampling on cycle day 2 of 3 of the menstrual cycle, patients will be followed up with blood and ultrasound from cycle day 10 onwards till the detection of serum LH peak. LH peak will be defined as an increase in serum LH above 20IU/LH. Five (5) days after the LH peak a single SC injection of 150 ìg corifollitropin alfa will be administered (Stimulation Day 1). Starting on Stimulation Day 6, the subject will receive a daily SC injection of 0.25 mg ganirelix up to and including the day of GnRH agonist triggering administration to prevent premature LH surges. From Stimulation Day 8 onwards treatment is continued with a daily SC dose of rFSH (200IU/day) up to the day of GnRHa administration.

Drug: Luteal phase corifollitropin alfa

Interventions

GnRH antagonist protocol with corifollitropin alfa initiated in the follicular phase (day 2 or 3 of the menstrual cycle)

Early follicular phase protocol

GnRH antagonist protocol with corifollitropin alfa initiated in the luteal phase (5 days after an LH peak)

Luteal phase protocol
