Når disse doser anvendes i et klinisk studie, hvor man sammenligner GONAL- f og urinderiveret FSH, er GONAL- f mere effektivt end u- FSH hvilket ses ved en lavere total dosis og en kortere behandlingsperiode, for at opnå præ- ovulatoriske forhold.
However, when these doses were used in a clinical study comparing GONAL-f and urinary FSH, GONAL-f was more effective than urinary FSH in terms of a lower total dose and a shorter treatment period needed to achieve pre-ovulatory conditions.
