Protocol with antagonist and hCG to trigger oocyte maturation
Protocol with antagonist and 0,2 mg triptorelin to trigger oocyte maturation
Long Protocol and hCG to trigger oocyte maturation
Material and Methods Between June and December of 2008 we evaluated 90 egg donors. They underwent COH with 150 IU rFSH as starting dose, we separated them in 3 groups (n:30 each): Groups 1 and 2 received a 0.25mg daily dose of GnRH antagonist when a follicle 14mm in diameter was observed. hCG 250g was given to group 1 while group 2 received triptorelin 0.2mg when leading two follicles were 17mm. Group 3 was stimulated with standard long protocol, hCG was given following similar criteria.
Blood was collected the day of hCG/aGnRH administration as well as the day of egg retrieval, and follicular fluid from the first two mature follicles was also frozen. We collected granulosa cells (GC) of 10 patients of each group as well Levels of VEGF, sVE-Cadherin an Angiopietin 2 were determined by ELISA in serum and in follicular fluid.
Results were analyzed via ANOVA.Data are expressed as mean± SEM. A significant difference was defined as p< 0.05.
