Overview of comparisons made in the experiments

Figure	Strain, Subjects	n	Analyses	Comparison	Statistical Test
2, 3	C57BL/6 wild-type mice, CONV-R	7	Androgens	Cecum and colon vs. small intestine	Wilcoxon pairwise signed rank
4	C57BL/6 wild-type mice, CONV-R	10	Androgens	Different tissues	No statistical test, descriptive
5, 6	C57BL/6 wild-type mice, GF and CONV-R	10	Androgens in intestinal contents	GF vs. CONV-R	Mann–Whitney U test
7D, 8, 9; Table 4	C57BL/6 wild-type mice, GF and CONV-R	8–10	Androgens, gonadotropins, tissue weights	GF vs, CONV-R	Student’s unpaired t test, 2 tailed
10	Young adult men	8	Androgens	Serum vs. feces	Student’s paired t test, 2 tailed

n = no. per group. CONV-R, conventionally raised; GF, germ free.
