If you don't know already your mouse is probably female, large testicles and male-like behavior are another hint. The testicles are pretty obvious in mice and rats. A male mouse's penis would be more where our belly buttons are. Also, in adult mice, testicles are usually easily visible.
Cryptorchidism is a medical condition wherein the testicles are undescended. Undescended testicles are testicles that don't move lower into the scrotum.
The location of the testicles is under the penis, in the scrotum.
Yes. Your testicles are inside the scrotum.
Urologists treat testicles.
No. Without testicles, there is nothing to create them.
