Anogenital distance is used to determine sex in which animals?

Explanation:
Anogenital distance is a sexually dimorphic measure that reflects prenatal androgen exposure. In mice and rats, the distance from the anus to the genital opening is consistently longer in males than in females, making it a straightforward, noninvasive way to determine sex in newborns and young animals. This clear difference is well established and standardized in these species, so AGD is routinely used in lab protocols for sexing and for studies of endocrine disruption. In hamsters, the sex difference in AGD is not as robust or consistently used, so mice and rats remain the best-supported pair for employing AGD to determine sex.
