Estrogen related chemical leaching

No idea! Scary thought!

https://en.wikipedia.org/wiki/Xenoestrogen
Maybe some stuff there.

The problem I see with all these analysis is interpretation of the results. What time period was the plastic amerced in the liquid during the test? Did the Estrogen leach out more at the beginning of the period, at the mid point or at the end?

The longest I have ever worn my aneros for is 4 hours and I only have a maximum of 4 sessions per week.

I'd be more worried with the American's obsession with drinking bottled water. (our tap water is good, we only use bottled water during outages or when theres a health scare, which is rare)
In fact, some of the "trap guides" I've seen seem to advocate drinking lots of bottled water because of the Xenoestrogens.

With an Aneros BPA plastic device in your butt, presumably an oil based lube would help reduce any uptake of the xenoestrogens.
And one of the selling points of Bad Dragon dildos was that they dont have the same dangers as other dildos - they use medical grade platinum silicone.
So I guess that makes the Aneros Syn models more healthy?

So i have been reading supportive literature about BPA- free plastics that still have estrogen like chemicals leaching feom them when tested in solvents of saline and ethanol. This is disturbing because of the health related issues that it derives. I was hoping to see some assay data on the plastics used for Aneros. Being the leaching described has been linked to testicular and prostate cancer it highlights concern being these instruments are so close to both? There has been some leaching concern on medical grade tubing as well. Any help here?

My best suggestion is to not get paranoid over study results on topics you dont understand.

Theres absolutely no way to know how low or high quality the materials in this linked study are. Some may be contaminated, some may be unstable.
The question comes down to Aneros' quality control.
Considering the success of this brand hinges at least partly on the medical viability of their products, it may be reasonably safe to assume the product isnt leeching chems into your bowels.
You could always take your aneros to a lab and see if its leeching chems or you could worry about something more dangerous like high fructose corn syrup, heavy metals in your water, or the dirty air you breathe everyday.
