vs. number of follicles ≧12 mm on hCG day	-0.38 (30)	<0.05	-0.24 (29)	0.20
vs. number of oocytes retrieved	-0.46 (30)	<0.05	-0.22 (29)	0.26
vs. number of oocytes fertilized	-0.47 (30)	<0.01	-0.16 (29)	0.42
vs. number of day-2 embryos	-0.41 (30)	<0.05	-0.01 (29)	0.95
% increase of serum MG-H1 from pre-trial value
vs. % day-2 embryos per retrieved oocyte	-0.45 (29)	<0.05	-0.21 (30)	0.26
Pre-trial serum MG-H1 concentration …
vs. % superior day-2 embryos per day-2 embryo	0.37 (30)	<0.05	-0.01 (30)	0.97
vs. endometrial thickness	0.11 (29)	0.56	-0.51 (30)	<0.01

^a Correlations between % increase of serum MG-H1 and % day-2 embryos per retrieved oocyte, and between pre-trial serum MG-H1 and endometrial thickness in the Hishi group, were analyzed by the Pearson test; all other correlations were analyzed by the Spearman test
