Title: Efficacy and Tolerability of Subcutaneous Progesterone (IBSA) Versus Vaginal Progesterone for Luteal Phase Support in Patients Undergoing In Vitro Fertilization (IVF)
Brief Summary: Prospective, open, randomized, parallel, multicenter, two-arm trial to evaluate the efficacy and tolerability of a new progesterone formulation to be used for luteal support in IVF (Progesterone-IBSA) administered subcutaneously at a daily dose of 25 mg versus Progesterone tablets administered intravaginally at 100 mg twice daily for a total dose of 200 mg.
