Brief Summary: The purpose of the current phase I study was to establish bioequivalence, safety, and tolerance of single 300 IU subcutaneous dose of follitropin alfa biosimilar (Primapur) in comparison to that of reference follitropin alfa preparation (Gonal-F) in healthy young female volunteers.

Detailed Description: A Phase I, prospective, randomized, open-label, crossover, 2-period, two treatment, clinical study in healthy female volunteers.

Objectives of the study:

1. To evaluate the frequency and severity of adverse events (AE) following a single 300 IU subcutaneous injection of Primapur (IVFarma, LLC, Russia) and Gonal-F (Merck Serono S.p.A., Italy) to healthy volunteers.

2. To determine the AUC0-t value of Primapur following a single 300 IU subcutaneous injection to healthy volunteers.

3. To determine the T½ value of Primapur following a single 300 IU subcutaneous injection to healthy volunteers.

4. To determine the Сmax value of Primapur following a single 300 IU subcutaneous injection to healthy volunteers.

5. To determine the Tmax value of Primapur following a single 300 IU subcutaneous injection to healthy volunteers.

6. To compare the obtained pharmacokinetic characteristics of Primapur and Gonal-F.
