Pergoveris FD and Liquid China BE Study

The main purpose of this study is to assess the bioequivalence (BE) of the fixed combination of follitropin alfa and lutropin alfa in Pergoveris freeze-dried (FD) (Test 1) or in Pergoveris Liquid (Test 2) versus the co-administration of Gonal-f and Luveris (Reference), administered subcutaneously (SC) in pituitary suppressed, healthy premenopausal Chinese female participants, at the doses of 900 international unit (IU) of follitropin alfa and 450 IU lutropin alfa.


Eligibility Criteria:
Inclusion Criteria:

* Participants who are overtly healthy as determined by medical evaluation, including medical history, physical examination, laboratory tests, and ECG, blood pressure (systolic and diastolic) and pulse rate
* Participants who have a negative serum pregnancy test before starting Marvelon and on the days before the Pergoveris or Gonal-f/Luveris dose
* Participants who are taking an oral contraceptive pill (OCP) for at least 1 month prior to Screening and are willing to take the combined oral contraceptive pill (COCP) during the study and to recommence taking their own OCP from Day 55 after the first Pergoveris or Gonal-f/Luveris dosing
