  1. 01LabEx vivo tissueActivity measurement

    In lab tests, cells from ganirelix-treated patients showed no significant effect of prior treatment on spontaneous steroidogenesis.

    In plain wordsIn lab tests, ovarian cells from ganirelix-treated patients had similar spontaneous steroid production to cells from patients receiving no GnRH analogue.

    Summary
    Such in vivo treatment did not result in significant effects of triptorelin or the two GnRH antagonists on spontaneous or human chorionic gonadotropin (hCG)-stimulated steroidogenesis.

    Summary · context
    Cells were obtained from patients treated with different protocols of COH. In addition to gonadotropins they received triptorelin, cetrorelix, ganirelix or no GnRH analogue.
    Summary · context
    Since there is some controversy about the action of GnRH agonists in the human ovary we also tested the effect of triptorelin on steroid production in cultured human granulosa lutein cells.
