Odd urate or sperm plug?

[Kiki_Leaf]

I've had my current Irian-Jaya for a few years now, and took "her" in when the previous owner surrendered (they had her roughly 16yrs I've had her for 4 now) and normally Turipi (name) goes to the bathroom in one specific section of her enclosure (makes for wonderful and easy clean up) but this morning Turi went in the water dish and I noticed that along with the white pearl of regular urate, there was also a large collection of mucus looking waste alongside it.

It's quite a lot, and I'm wondering if this is sperm? I'm waiting on a call back from the vet since Turi is due for her yearly check up soon, so I figure I might as well check here to know if it's worth bringing it in for the vet or not.

I've never had a male skink before, so I'm not sure how much the volume of their plugs or ejaculate would be, as my other reptiles give off smaller amounts when the males push some out purely because they're smaller reptiles.

Photo attached. It has sat a couple minutes so it's not as clear as it was when it first came out.

Sperm plugs

That doesn't look like sperm plugs I have seen before but with the water spreading things out it's certainly possible. The vet should know for sure tho!
