Histomorphometric changes in the epididymis of antibiotic-treated and saline control male mice.

Group	# of males having cribriform changes in the epididymal epithelium	# of males with mature cribriform cysts in the epididymal epithelium	# of males with mitotic figures in the epididymal epithelium
Antibiotic treated	7/10*	5/10**	3/10***
Control	3/10	1/10	0/10

^*P value comparison of antibiotic-treated to control males = 0.01;

^**P value comparison of antibiotic-treated to control males = 0.02;

^***P value comparison of antibiotic-treated to control males = 0.03.
