Figure 6. The relationship between serum GDF-8 level and P4 level.

Figure 6

(A) GDF-8 level was negatively correlated with P4 level in serum on hCG day. (B) The decrease of GDF-8 level was accompanied by the increase of P4 level in serum at the time points as indicated. The results are expressed as the mean ± SEM. (C) From hCG day to OPU day, the decrease of GDF-8 was positively correlated with the increase of P4 level in serum.
