Figure 5. The relationship of serum GDF-8 with P4 level changes and pregnancy results from hCG day to OPU day.

Figure 5

(A) Patients were divided into two groups according to the cut-off level for GDF-8 decrease in serum from hCG day to OPU day (GDF-8 decrease <1.3 ng/ml vs GDF-8 decrease ≥1.3 ng/ml). Serum P4 level was measured by ECLIA in the two groups. B, Patients were divided into two groups according to the cut-off levels for GDF-8 decrease in serum from hCG day to OPU day (GDF-8 decrease <1.3 ng/ml vs GDF-8 decrease ≥1.3 ng/ml). The pregnancy rate was calculated and compared between the two groups. The results are expressed as the mean ± SEM or number.
