¿Hay diferencias entre las gonadotropinas disponibles para la estimulación ovárica en técnicas de reproducción asistida?

The published results do not demonstrate that urinary-derived FSH or hMG, alone or when data are pooled, are more effective than recombinant FSH. In contrast, recombinant gonadotrophins have been shown to be more effective than urinaryderived gonadotrophins as a whole.
