Airway exposure to multi-walled carbon nanotubes disrupts the female reproductive cycle without affecting pregnancy outcomes in mice

Table 1 Regularity of the post-exposure cycle relative to estrous stage at exposure

		Post-exposure cycle Number of animals with
Estrous stage at exposure^a		Regular	Irregular
Diestrous	Control	3	1
Diestrous	Exposed	1	1
Proestrous	Control	2	0
Proestrous	Exposed	1	0
Estrous*	Control	5	0
Estrous*	Exposed	2	5
Metestrous	Control	4	2
Metestrous	Exposed	6	3

^aIncluding only regularly cycling animals during the pre-exposure cycles
*p = 0.027, Fisher's exact test (p = 0.026 when proestreous and estrous were pooled)
