Results After 3 months, E2/T had significantly reduced in Yi jin jing group (9.14±3.82) compared with control group (11.05±5.24)(P=0.04), and T level had significantly increased [(14.54±4.80) nmol/L, (13.74±3.80) nmol/L, P=0.02], FSH level had significantly increased [(11.67±6.21) IU/L, (9.58±5.05) IU/L, P=0.04] and LH had significantly increased [(7.96±6.58) IU/L, (5.00±1.68) IU/L, P=0.01].
