Criteria
Inclusion Criteria:

- Informed Consent Documents signed prior to any trial-related procedure.

- In good physical and mental health in the judgement of the investigator.

- Pre-menopausal women between the ages of 35 and 42 years. The subjects must be at
least 35 years (including the 35th birthday) when they sign the informed consent and
no more than 42 years (up to the day before the 43rd birthday) at the time of
randomization.

- Body mass index (BMI) between 17.5 and 38.0 kg/m^2 (both inclusive) at screening.

- Infertile women diagnosed with tubal infertility, unexplained infertility,
endometriosis stage I/II or with partners diagnosed with male factor infertility,
eligible for in vitro fertilization (IVF) and/or intracytoplasmic sperm injection
(ICSI) using fresh or frozen ejaculated sperm from male partner or sperm donor.

- Documented history of infertility for at least 6 months before randomization (not
applicable in case of tubal or severe male factor infertility, or when the use of
donor sperm is indicated).

- Regular menstrual cycles of 24-35 days (both inclusive).

- Hysterosalpingography, hysteroscopy or saline infusion sonography, documenting a
uterus consistent with expected normal function (e.g. no evidence of clinically
interfering uterine fibroids defined as submucous fibroids of any size 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) at screening or
within 1 year prior to screening.

- Transvaginal ultrasound documenting presence and adequate visualization of both
ovaries, without evidence of significant abnormality (e.g. enlarged ovaries which
would contraindicate the use of gonadotropins) and normal adnexa (e.g. no
hydrosalpinx) at screening. 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 randomization).

- Negative serum Hepatitis B Surface Antigen (HBsAg), Hepatitis C Virus (HCV) and Human
Immunodeficiency Virus (HIV) antibody tests at screening or within 6 months prior to
screening.

- Willing to accept the blastocyst transfer policy for the fresh cycle and the
cryopreserved cycles initiated within 12 months from the start of controlled ovarian
stimulation using blastocysts obtained in this trial, i.e. transfer of one blastocyst
(if a good-quality blastocyst is available) or transfer of one or two blastocysts (if
no good-quality blastocyst is available).

Exclusion Criteria:

- More than one previous controlled ovarian stimulation cycle for IVF/ICSI.

- Known endometriosis stage III-IV (defined by the revised ASRM classification, 2012).

- Known history of anovulation.

- One or more follicles greater than or equal to 10 mm (including cysts) observed on the
transvaginal ultrasound prior to randomization on stimulation day 1.

- Known history of recurrent miscarriage (defined as three consecutive losses after
ultrasound confirmation of pregnancy [excluding 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. In case partner
sperm will be used and the sperm production is severely impaired (concentration less
than 1 million/mL), normal karyotype, including no Y-chromosome microdeletion, must be
documented.

- Any known clinically significant systemic disease (e.g. insulin-dependent diabetes).

- Known inherited or acquired thrombophilia.

- Active arterial or venous thromboembolism or severe thrombophlebitis, or a history of
these events.

- Any known endocrine or metabolic abnormalities (pituitary, adrenal, pancreas, liver or
kidney) with the exception of pharmacologically controlled sub-clinical
hypothyroidism.

- Known tumors of the ovary, breast, uterus, adrenal gland, pituitary or hypothalamus
which would contraindicate the use of gonadotropins.

- Known moderate or severe impairment of renal or hepatic function.

- Any abnormal finding of clinical chemistry, hematology, thyroid-stimulating hormone
(TSH) or prolactin, or vital signs at screening, which is judged clinically
significant by the investigator.

- Known abnormal cervical cytology of clinical significance observed within three years
prior to randomization (unless the clinical significance has been resolved).

- Findings at the gynecological examination at screening which preclude gonadotropin
stimulation or are associated with a reduced chance of pregnancy, e.g. congenital
uterine abnormalities or retained intrauterine device.

- Pregnancy (negative urinary pregnancy tests must be documented at screening and prior
to randomization) or contraindication to pregnancy.

- Known current active pelvic inflammatory disease.

- Use of fertility modifiers during the last menstrual cycle before randomization,
including dehydroepiandrosterone (DHEA), metformin or cycle programming with oral
contraceptives, progestogen or estrogen preparations.
