• Each subject must be able to adhere to dose and visit schedules and willing to disclose any medical events to the investigator.

Exclusion Criteria:

• The subject has a recent (ie, within 3 years) history of/ or any current endocrine abnormality (irrespective whether the patient is stabilized on treatment).
• The subject has a history of ovarian hyper-response (ie, previous IVF cycle with more than 30 follicles ≥11 mm on ultrasound) or ovarian hyperstimulation syndrome (OHSS).
• The subject has a history of/or current polycystic ovary syndrome (PCOS)
• The subject has more 20 basal antral follicles <11 mm (both ovaries combined) as measured on ultrasound in the early follicle phase (menstrual cycle day 2-5).
• The subject has less than 2 ovaries in any other ovarian abnormality (including endometrioma > 10 mm; visible on ultrasound).
• The subject has unilateral or bilateral hydrosalpinx (visible on ultrasound, less clipped).
• The subject has any intra-uterine fibroids >5 cm or any clinically relevant pathology, which could impair embryo implantation or pregnancy continuation.
• The subject has more than three unsuccessful treatment cycles for IVF/ICSI.
