6. Menstrual cycle: history of a normal menstrual cycle before combined oral contraceptive pill use;
7. hCG: endogenous hCG levels <1.2 IU/L at screening and Day -1, Period 1;
8. Pituitary down-regulation: Luteinizing hormone (LH) <5 IU/L; Follicle stimulating hormone (FSH) <4 IU/L at Day -1, Period 1;
9. Papanicolaou smear (PAP) test: negative or not clinically significant PAP test results within 12 months before the screening visit or at screening;
10. Full comprehension: ability to comprehend the full nature and purpose of the study, including possible risks and side effects; ability to co-operate with the investigator and to comply with the requirements of the entire study;

11. Additional contraception: study participants with an active sexual life must be using one additional contraceptive method, as follows:

    1. A male sexual partner who agrees to use a male condom with spermicide
    2. A sterile sexual partner.

Exclusion Criteria:

1. Contraindications: any contraindications to combined oral contraceptive pill or gonadotropins;
2. Electrocardiogram 12-leads (supine position): clinically significant abnormalities;

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Rate of absorption (Cmax)	To assess the bioavailability of the test and reference products in terms of rate (baseline-corrected, dose-normalised Cmax) of hCG absorption after single s.c. injection to healthy female subjects.	192 hours post dose
Extent of absorption (AUC0-t), Area under the concentration-time curve	To assess the bioavailability of the test and reference products in terms of extent (baseline-corrected, dose-normalised AUC0-t) of hCG absorption after single s.c. injection to healthy female subjects.Area under the concentration-time curve from administration to the last observed concentration time t, calculated with the linear trapezoidal method.	192 hours post dose

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
t1/2: Half-life	To evaluate the baseline-corrected, dose-normalised (when applicable) t1/2 (Half-life) value after single dose administration of test and reference products;	192 hours post dose
Tmax: Time to achieve Cmax	To evaluate the baseline-corrected, dose-normalised (when applicable) Tmax value after single dose administration of test and reference products;	192 hours post dose
AUC0-∞: Area under the concentration-time curve extrapolated to infinity		192 hours post dose
Frel : Relative bioavailability	calculated as dose-normalised ratio AUC0-t (T)/dose(T) / AUC0-t (R)/dose(R)	192 hours post dose
Treatment emergent adverse events (TEAEs)	percentage of subjects with any TEAE	through study completion up to 46 days.
