Abstract:
Objective To investigate the relationship between the zinc and copper concentration and the clinical outcomes of in vitro fertilization and embryo transfer(ivf-et).Methods The clinical data and zinc and copper concentration of serum on the days with human Chorionic gonadotropin(hCG) injection as well as that in the follicular fluid on the the day of oocyte retrieval were retrospectively analyzed in 43 cases with IVF-ET cycles.Results Application of pearson correlation analysis showed that copper concentration in follicular fluid of the 43 cases was positively correlated with the numbers of retrieved oocytes,fertilized oocytes and cleaved embryos( r were 0.392,0.327 and 0.321,respectively,P were 0.0094,0.0325 and 0.0361 respectively ) Between the pregnant group and non-pregnant group,the zinc and copper concentration in follicular fluid was not significantly different ( P ＞ 0.05 ) ; the serum estradiol ( E2 ) on the day of hCG administration was of significantly different(t =2.177,P =0.0353 );the serum zinc concentration on the day of hCG administration was of significantly different ( t =2.153,P =0.0372).Conclusion Trace elements zinc and copper might play an important role in the process of IVF-ET.
