Relationship between expression of follicle-stimulating hormone receptor in granulose cells and ovarian response in in vitro fertilization cycles / 上海第二医科大学学报

ABSTRACT

Objective To investigate relationship between levels of follicle-sitimulating horomone receptor(FSHR) and ovarian response induced by gonadotropin hormone,and whether the FSHR expression is correlated with in vitro fertilization(IVF) outcome.Methods Granulose cells were collected from 43 women receiving IVF-embryo transplantation(IVF-ET).According to the number of oocyte,the women were divided into three groups: low response(15).The expression intensity of FSHR was measured by immunohistochemistry technique.The expression intensity of FSHR on the granular cell,the embryological and clinical outcomes were compared and analyzed. Results The expression of FSHR was significantly different in three groups with the highest in high response group(P0.05).The FSHR level was positively correlated either with the number of oocyte (r=0.719) or with the serum E2 levels(r=0.516,P0.05). Conclusion Ovarian response to gonadotropin hormone stimulation is correlated with the level of FSHR in the granulose cells.The development of follicles may be influenced by it.
