I do not know the answer to this for sure, however, I recently took our 7 week old male pot belly pig to be neutered, and the vet cut where the testicles should be...and found none. She then cut higher and again found none what-so-ever. She stated that he was either born without both testicles (rare - less than 1% born without both testicles), or that they are in his abdomen. She then advised to keep an eye on him for another month and see if any testicles descend or if he becomes aggressive and gets that musky male odor that intact boars get. If so, we are to take him back and if no testicles have descended, then she will have to open his abdomen and look around in there to see if that is where they are. If she does not find the testicles there, then it will mean that he was born without both testicles. I would love to have a clear answer from someone "in the know" on this however. Thanks
They do have testicles but are much smaller than a full grown guinea pigs.
A human male without testicles.
About 3-4% of full-term male infants are born with undescended testicles.
Only a doctor can determine that, a hermaphrodite has both sex organs of both male and female.
Male hamsters have very prominent testicles between its back legs on its belly side. If it does not have these, it is a female.
Yes. That determines it to be male, along with another male organ called a penis. Sometimes the testicles do not descend down from the abdomen and are retained. You must have your Veterinarian do surgery to get them out as they can turn cancerous if left in. Male dogs are born with testicles, but they are generally inside the abdomen. The testicles usually "drop" by coming through the inguinal canal any time after 4 weeks of age.
A male horse with its testicles in tact is called a stallion, a male horse without them is called a gelding.
Only if they're Male to Female transexuals (MTF)
If it is a male it will have no testicles. If it is a female, she will not go into heat. You can sometimes see a small scar from the surgery on a female down low on the belly.
You cannot "grow" testicles. But if you are male you should have testicles and they will develop as you grow.
No male mammal is born without a penis - male cats included.
If you look at a ferret's belly, there will be what some people call "the belly button". This is the male genitalia, which is luckily quite easy to spot without having to look too closely.
The average young male donkey will drop his testicles shortly after birth. The testicles will drop down with them 24 hours of birth.
