Young males and females are not easily distinguished; females have a significantly smaller distance between their An*s and genital opening. When sexually mature, the most striking and obvious difference is the presence of testicles on the males. These are relatively large compared to the rest of the body, being approximately half the size of the mouse's skull and usually hairless. They can be retracted into the body. Females have 5 pairs of mammary glands and nipples; males have no nipples.What are the differences in mice genders?
