Aside from actually implanting the thing in the first place - I wouldn't fancy injecting one of those into a guinea-pig (concious or under-GA) using the needle and applicator provided!

I always use a brief sevo GA as I figure that wouldn't like a needle equivalent sized to my finger being stuck into me so why would they? (And I really don't like the squeaking of an irate guinea pig, it's like nails down a blackboard to my ears)

[quote user="Jillian Hall"]On a largely unrelated subject, I've recently had to give Chorulon to a cryptorchid puppy (Against my advice, which was obviously just to castrate it- the owner has no intention of breeding him, just wants a dog with a perfect set of plums.). It used to have a licence for this purpose. It hasn't made the slightest bit of difference. Has anyone else used Chorulon for cryptorchids with any success?[/quote]

The data sheet still says "Chorulon has been used in cases of cryptorchidism in the dog prior to castration (100-500 iu i.m. twice weekly for up to 6 weeks)."

I too have tried it without success.

Martin - small non-functional ones are asymptomatic (up to 90% of GPs have cysts at p-m). Non-functional large ones appear as space-occupying lesions with a distended abdomen and vague signs of discomfort (lethargy, intestinal stasis, reduced appetite). Functional cysts tend to cause bilateral flank alopecia with occasional pruritus and breeding failure.

They are usually easily palpable but diagnosis can be confirmed ultrasonographically.

You could ultrasound guided drainage to relieve the pressure on other organs if cysts are large, followed by GnRH agonists - Suprelorin (deslorelin) implants are being suggested as a longer-acting option - to prevent/slow recurrence. The downside to this approach is that the GnRH agonists are believed to promote uterine leiomyoma formation so surgical correction remains the best treatment.

I have used Chorulon in a g pig belonging to one of my nurses. I cant remeber the exact protocol, whatever the standard was in the literature. The response wasn't great. I think it initially seemed to pick up but cant remeber for how long. Eventually we opted for spaying but it dies on recovery from GA. (It was a particularly ropey looking specimen to start with)

Two very large, palpable masses in dorsal abdomen. No imaging usually required, although xray will confirm. The ovaries do get really massive.

I have a client who rescues Guinea Pigs and has 3 which are showing the clinical signs of ovarian cysts. She is not keen to spey them and was enquiring re medical treatment. I have read a few reports on the internet involving Chorulon and was wondering if anyone has experience with this and what the success is and protocol for use? Also could you use Receptal - I havent read any data regarding its use in Guinea Pigs?

Any ideas would be appreciated!

Hmmm...so what are the clinical signs of ovarian cysts in Guinea Pigs? I'm not sure I'd be confident to diagnose them in a bitch without imaging.

Thanks, I have told her speying is the recommended treatment. I did also call Intervet but they didnt have much info on it hence my query on Vet Surgeon to get help from people who may have tried it before...

not usually cancerous.

Haven't tried medical treatment I'm afraid - I have found spaying very successful and not particularly challenging in most cases.

May I suggest ringing Intervet?

Don't we think these are often cancerous change?
