The great testicle hunt: Cryptorchidism in pet practice

December 22, 2007 / (6) comments


The definition of stress: over thirty minutes spent hunting down the exact location of a stray testicle in a dog’s abdomen. In the abdomen? Yep. Because it ain’t hanging between his legs like it should be. Instead, it’s stuck up in his insides making trouble for those of us on the outside who are simply trying to make sure it doesn’t turn into cancer or get all wrapped up in guts.

When testicles don’t descend into their proper place inside the scrotum, we call the condition cryptorchidism. It’s a reasonably benign problem most of the time. Problem is, a significant percentage of these dogs have issues with these bad boys when they stay inside their bellies.

As I alluded to earlier, cryptorchid testicles have a way of courting cancer in higher temperature environments (when they can’t hang out and be cool in their happy sack). Occasionally, they even getting twisted into the intestines or other abdominal structures (which can lead to gut or testicular necrosis and subsequent peritonitis).

Life sucks when testicles do strange things. That’s because it typically takes about five times as much work to neuter a dog with a “lost” testicle and sometimes as much as ten times the stress of a normal spay. And that can’t be good. After all some “routine” spays can seem anything but. (See my post on this.)

So you know, we always advocate neutering dogs with cryptorchidism. That’s because 1-the wayward testicle is a potential liability and 2-the problem is hereditary, meaning that if he’s allowed to breed he’s more likely to pass on this unwanted trait to his babies. And that can’t be good, either. I mean, who wants more lost, precancerous belly mines in the general population?

But it isn’t always as easy to do as you might think. Whenever a pet’s body gets up in arms and decides it wants to do funny things most other pet bodies don’t do, vets must suffer the consequences. To compensate for the pathology, we have to use our wits, our experience and our creativity to find these wily bits of body in their strange places.

True, it gets easier with more experience, but a testicle isn’t always an easy thing to find in an abdomen full of fat, blood, guts and similarly-hued sliminess. Where’s Waldo is an especially hard game to play when the testicle is shrunken to the miniscule proportions reflecting its uselessness. Following the path of teeny tubes attached to the testicle is often the only way to discover its hiding place—easier said than done.

Though nine out of ten times I’m rewarded with the satisfying sight of the testicle within a couple of minutes, the other ten percent leaves me scratching my head (figuratively, that is, gloved and gowned as I am) and regrouping for another back-aching look see (I have some upper back pain that gets the better of me when I’m both stressed and hunched over, simultaneously).

That’s why when I finally find the wicked thing I like to yell, “Eureka! I’ve found your testicle!,” which makes everyone laugh as I sew up the abdomen and turn up the volume on the Ride of the Valkyries playing in my head.

Just wanted to pass on my own, recent cryptorchid experience. A young, cross-eyed DSH named Ziggy presented for a neuter and I found him to be cryptorchid. When I opened his abdomen to go a-testicle-hunting his uterus popped up. That's right, his uterus. It was very easy to find his other testicle when it was an ovary attached to a pedicle just south of the kidney. The other horn descended through his inguinal ring and attached to his testicle. Weirdest neuter ever. Unfortunately the owners did not have funds available for pathology to determine if tissue was male or female. I will just have to save his uterus, ovary and testicle in a jar for posterity and good conversation.

DrSteggy: Yeah, I hate when that happens... Here's one from 2 weeks ago: My last blocked cat turned out to be a hermaphroditic one. He had no visible testicles and his owners just assumed he had been neutered early. Catheterizing an enlarged clitoris isn't exactly on anyone's menu--especially when there's no visible urethra anywhere near it. Turned out to be an emergency PU, of course. Sucks for him...or her...I'll know when I go looking for testicles next month. Not looking forward to it...

Resolving Cryptorchidism can be a stressful and back-breaking procedure. I've found it goes easier if you:

1. Do some gentle stretching before you begin,

2. Take a deep, cleansing breath, and

3. Keep your eye on the ball!

Ba dump de dump. Thank you folks, I'll be here all week. Please remember tip your servers and try the veal.

Merry Christmas - Larry

The 5.5 year old male doberman/black lab mix I recently acquired from a relative had never been neutered, and (go figure) had his L testicle retained in his abdomen. The poor doc I work for was up past his wrists for about an hour in my guy...I felt just a little guilty when I noticed how bad he was sweating (the doc, not my dog...I suppose it's not easy having the owner of a pet on your table be in the room w/you watching your every move like a hawk).

Oh man. Once upon a time we saw a dog who we THOUGHT was a bilateral cryptorchid. We started seeing the dog when he was 8 weeks old, and the owners got him from friends who accidentally bred a litter, so there was NO CHANCE this pup was neutered young.

Well, we went to neuter him after preparing the owners for MONTHS that this was going to be a project and lo and behold, after 45 minutes of searching, I called in help and after 3 of us looked, nothing, no testicles...we could find the testicular ARTERY and follow it into the inguinal canal, and my that sure looked like a cremaster going in the same direction, but there was nothing on the end!

We closed him up and drew blood for a testosterone level. And yeah, he had ZERO testosterone. Turns out we had the one dog in a bazillion with bilateral testicular agenesis.

Yeah, that was a hoot.

My Mom had a colt with cryptorchidism and imo castrating/recovery for horses is nasty business under the best of conditions. She was so thankful when it was over.

Keep up the good work and happy hunting! :)
