Serum hormone profiles.

Hormone	LowP (11 data sets)	HighP (10 data sets)	Significance
Estradiol (pg/mL)	134 ± 22	103 ± 12	NS
Progesterone (ng/mL)	0.33 ± 0.09	8.74 ± 2.20	p = 0.001
Testosterone (pg/mL)	280 ± 27	230 ± 26	NS
Cortisol (mcg/dL)	9.2 ± 1.6	8.2 ± 1.1	NS

Only data-sets where estradiol levels were high (>51 pg/mL) were included, these were subdivided on the basis of progesterone levels into low (LowP; progesterone <1.0 ng/mL) and high (HighP; progesterone >1.0 ng/mL) groups. Data are presented as means ± SEM. Two-tailed linear mixed models were used to assess for an effect of group, taking into account repeated measures and the unbalanced size of the groups.
