ABSTRACT

Background: With the use of new protocols Controlled ovarian hyperstimulation (COH) with lower doses of gonadotropins to the classics protocols and current trend of fewer embryos transferred, there is no agreement until today on the optimal dose start of a COH protocol.
Objective: Compare the results of two flexible protocols of HOC with different starting doses (150 vs 225 IU rFSH / hMG) plus a GnRH antagonist in cycles of IVF / ICSI.
Methods: Retrospective, descriptive study, we analyzed 231 cycles of IVF / ICSI being the primary variables: total FSH dose, dose increase, retrieved oocytes, embryos available for transfer and for cryopreservation.
Results: The total dose of FSH in group II was significantly higher versus group I (2096.0 vs 1447.9). The percentage of patients in whom the dose increased was higher in Group I vs Group II (26.4% vs 9.1%, p = 0.001). The number of retrieved oocytes was similar between the groups (10.5 vs 10.2, p = 0.76) as well as the number of embryos available the day of the transfer and the number of embryos that were vitrified 6.73 vs 6.08 (p = 0.97) and 1.5 and 1.3 (p=0.820) for Group I and II respectively. The clinical pregnancy rate was 39.3% (n = 91), and for groups I and II were 41.6 and 37.7% respectively.
Conclusions: No significant differences between two loading dose was found (150 vs ≥ 225) in most of the primary endpoint.
