Sexing Male or female?

I never thought I'd need to post one of these threads because it seems pretty straightforward ;) I've sexed 7 females before and they were all easy to see. I've only ever seen one male and he was very obvious as well.
So when I found this lovely agounti at the shelter I thought she'd be easy to verify......
The shelter swears she's a female, I looked and thought-no, that's a male.
I did the push test-nothing. I did it again, nothing. The worker said she was sure it was a female. I wanted to believe her. The pig's teets are very long which I know is not a big deal since they both have teets.
I did the push test again. Nothing popped out and it wasn't the classic Y or "dotted Y"
I took "her" because I WANTED to believe she was a she LOL
But I know that was pretty dumb really.

So here you go:


It's more like a "fold of skin" vs a tube that is confusing me. And I've done the "push test" 3 or 4 x now!

So weigh in because I certainly can't put my girls together unless I'm 100% sure! (After the quarantine of course)

this is a 100% young male
 
so do u think it's a boy or a girl?
 
Have tried rubbing your finger across her body just above the genitalia to see if you can feel a ridge? That, and being able to extrude the penis, are pretty much the acid tests for determining males. But, there are guinea pigs with ambiguous genitalia, as well as hermaphrodites, just as there are humans.

How old is this pig? And do you see any indication of testicles? The hand blocks that area in the picture.
 
The pig is "supposed to be" 1 yr-that is what the shelter was told.
I did not see any testicles which is partly why I took her from the shelter.

hmmm-more rubbing I guess is needed LOL
 
If you don't see any testicles and you can't feel or extrude a penis, it's probably safe to say she's female.
 
I should say there are no "obvious" testicles. The only ones I've seen are obvious. Could it be that he/she is young enough that they would not be obvious?

I do think the age is close. She might be a little less than a year but not much. She is smaller than my girls were when I got them at 1.5yrs but not by a lot.
 
They should be very obvious at a year old. But sometimes they're small, but always sort of in a doughnut ring shape.
 
Sure looks like a boy to me
 
Sometimes it's really hard to tell. I have one that I really wasn't sure about. I finally asked my vet who said she was a female which is what I was told she was by the previous owner.
 
The "donut shape" around the genitals could be the testicles right? My females don't have this "donut" around their Y. You can see in the pic that it does have a donut type shape around the opening or at least a mound that comes out from the torso.

I've tried another couple times to get something to pop out by massaging and everything I've read but all I can do is get that " fold of skin" to pop out more. Which makes me think it must be a male and he's just not interested in sharing his business. ;)

Sigh....now to figure out what to do.
 
Can you post a picture of the donut shape?
 
It's in the picture above-in between my fingers. It's a "mound" that definitely sticks out from the torso. There is nothing beyond that under my fingers.
 
The testicles should look more like pictures #8 or #12 on the sexing page.
 
my guinea pigs bum looks like a mound, like she said

like ion the first picture on this thread
 
If that's as far as that nub comes out, I think it's a female. However, I would like to see more photos. One from behind, and one of the genitals without your fingers.
 
The little nub does come out further when things are pulled apart a little-I just can't get anything to pop out of the nub.
You can't see anything from the back-nothing is hanging down if that's what you mean.

I'll try to get another pic or 2.
 
Do you feel a ridge above it? Sometimes it takes you pressing just right to get it to pop out. But, I have three boys and they all look like that. I haven't even bothered to press on the newest one. I can tell and I can feel the ridge.
 
I really tried to feel for a "ridge" and don't feel anything like that. It's just a solid bump.
