title: [Ovulation stimulation. FIVNAT].
abstract: In 1995, there was an increased use of GnRH analogs in IVF French programs, there was too an increase in the use of FSH (alone or combined with hMG). In general population, the best results are always obtained by the use of GnRH analogs in long protocols, pure FSH significantly increase the pregnancy rates. In a selectioned population (less than 35 years old, 1st IVF attempt and sperm and ovulation normal), pregnancy rate remains the best in long protocols, and pure FSH always improves the results (significantly in short protocols).
