A retrospective observational anonymized cohort study of follitropin alpha biosimilar (Primapur®) as a pre-filled pen injector with a dose adjustment of 5 IU, aimed to investigate its efficacy and safety in a nonselected population with indications to assisted reproductive technologies (ART) was carried out. The ovarian stimulation (OS) protocols included:~monotherapy protocols with using only Primapur®; mixed protocols (recombinant and urinary-derived gonadotropins); short protocols with using antagonists of gonadotropin-releasing hormone (GnRH) and long protocols with GnRH agonists. The stimulation protocols were analyzed with Primapur® application for at least 5 days.
