There is one clinical trial.
The study evaluates the influence of corifollitropin alfa (Elonva) on embryo morphokinetics and fertility treatment outcome in comparison to a control group stimulated with Follitropin beta (Puregon).
Follicular fluid (FF) were examined for oocytes under constant conditions of 37 °C in an IVF workstation L24E with heating stage (K-SYSTEMS Kivex Biotec A/S). --- L24E ---

Measure: Morula stage Time: 92 hours after fertilizationDescription: The influence of ELONVA versus PUREGON on the number of oocytes retrieved will be assessed.
Measure: Number of oocytes retrieved Time: Number of oocytes retrieved will be evaluated after one treatment cycle (each cycle is between 28 and 35 days)Description: The influence of ELONVA versus PUREGON on the maturity stage of oocytes (germinal vesicle, metaphase I (MI) or MII phase) retrieved will be assessed.
Measure: Stage of oocyte development Time: Stage of oocytes retrieved will be evaluated after one treatment cycle (each cycle is between 28 and 35 days)Description: The influence of ELONVA versus PUREGON on the number of fertilized oocytes will be assessed.
