Aim:
To investigate follicular fluid IGF 1, IGFBP 3 and their effects on IVF outcome in patients using different gonadotropins.
Materials And Methods:
This prospective study was performed among 92 IVF patients who were categorized according to IVF pregnancy outcome. Two groups were formed as Group 1 : pregnant, Group 2: non pregnant.
Results:
Follicular IGF 1 and IGFBP 3 levels were not different between the two groups. There were negative correlations between follicular IGF 1 and age, gonadotropin dose, embryo numbers in all patients and group 2, but there were no correlations between IGF1 and these parameters in group 1. Although IGFBP 3 levels were not different in patients using rec FSH or HMG, IGF 1 were higher in patients treated by rec FSH compared to patient using HMG. When the groups using rec FSH or HMG were analyzed according to pregnancy rate, there were no differences in IGF 1 levels.
Conclusion:
Follicular IGF 1, IGFBP 3 do not predict clinical IVF outcome regardless of the different gonadotropin preparations.
