Outcome Measures
Primary Outcomes (2)
Ongoing Pregnancy Rate
Ongoing pregnancy was defined as at least one intrauterine viable fetus 10-11 weeks after blastocyst transfer.
10-11 weeks after blastocyst transfer
Ongoing Implantation Rate
Ongoing implantation rate was defined as the number of intrauterine viable fetuses 10-11 weeks after transfer divided by number of blastocysts transferred.
10-11 weeks after blastocyst transfer
Secondary Outcomes (21)
Vital Pregnancy Rate
5-6 weeks after blastocyst transfer

Day of oocyte retrieval
Proportion of Subjects With Early OHSS (Ovarian Hyperstimulation Syndrome) and/or Preventive Interventions for Early OHSS
≤9 days after triggering of final follicular maturation
Proportion of Subjects With Cycle Cancellation Due to Poor Ovarian Response or Excessive Ovarian Response

Eligibility Criteria
You may qualify if:
- Informed Consent Documents signed prior to screening evaluations
- In good physical and mental health
- Pre-menopausal females between the ages of 18 and 40 years
- Infertile women diagnosed with tubal infertility, unexplained infertility, endometriosis stage I/II or with partners diagnosed with male factor infertility, eligible for in vitro fertilisation (IVF) and/or intracytoplasmic sperm injection (ICSI) using fresh or frozen ejaculated sperm from male partner or sperm donor
- Infertility for at least one year before randomisation for subjects ≤37 years or for at least 6 months for subjects ≥38 years (not applicable in case of tubal or severe male factor infertility)
- The trial cycle will be the subject's first controlled ovarian stimulation cycle for IVF/ICSI
- Hysterosalpingography, hysteroscopy, saline infusion sonography, or transvaginal ultrasound documenting a uterus consistent with expected normal function (e.g. no evidence of clinically interfering uterine fibroids defined as submucous or intramural fibroids larger than 3 cm in diameter, no polyps and no congenital structural abnormalities which are associated with a reduced chance of pregnancy) within 1 year prior to randomisation
- Transvaginal ultrasound documenting presence and adequate visualisation of both ovaries, without evidence of significant abnormality (e.g. no endometrioma greater than 3 cm or enlarged ovaries which would contraindicate the use of gonadotropins) and normal adnexa (e.g. no hydrosalpinx) within 1 year prior to randomisation. Both ovaries must be accessible for oocyte retrieval.
- Early follicular phase (cycle day 2-4) serum levels of FSH between 1 and 15 IU/L (results obtained within 3 months prior to randomisation)
- Body mass index (BMI) between 17.5 and 32.0 kg/m2 (both inclusive) at screening
You may not qualify if:
- Known endometriosis stage III-IV
- One or more follicles ≥10 mm observed on the transvaginal ultrasound prior to randomisation on stimulation day 1
- Known history of recurrent miscarriage (defined as three consecutive losses after ultrasound confirmation of pregnancy (excl. ectopic pregnancy) and before week 24 of pregnancy)
- Known abnormal karyotype of subject or of her partner/sperm donor, as applicable, depending on source of sperm used for insemination in this trial.
- Any known clinically significant systemic disease (e.g. insulin-dependent diabetes)
- Any known endocrine or metabolic abnormalities (pituitary, adrenal, pancreas, liver or kidney) which can compromise participation in the trial with the exception of controlled thyroid function disease
- Known tumours of the ovary, breast, uterus, adrenal gland, pituitary or hypothalamus which would contraindicate the use of gonadotropins.
