Dynamic measurements of serum inhibin B and estradiol: apredictive evaluation of ovarian response to gonadotrophin stimulation in the early stage of IVF treatment

Objective We dynamically measured serum inhibin B and estradiol in the early stage of hormonal stimulation to predict the ovarian response in in vitro fertilization (IVF) treatment. Methods A total of 57 patients (35 years did not reach pregnancy. Conclusions (1) Serum inhibin B and estradiol concentrations obtained shortly after Gn therapy may offer an accurate and early prediction of ovarian response; (2) Low levels of serum inhibin B and estradiol obtained shortly after Gn stimulation indicate the need for a longer period of Gn treatment and a higher daily dosage; (3) No obvious pregnancy difference among patients of age 35 years.
