If u were treated for chlamydia than used a toy for pleasure not positive if it was cleaned or not could you be reinfected? what are the chances?

Interesting question: There are several variables when you look at an object as a germ carrier.Some relate to the object like design and surface variations and some vary with the hardiness of germs when left to dry out. A good practice would be to always consider it possible, and regularly sanatize the toy.Soap and water and or the steam wands can help.

Possible: It is possible. Depends on the timeline. It also depends on if treatment was still ongoing. See this study for some info. http://www.ncbi.nlm.nih.gov/m/pubmed/8536467/. I would strongly consider retesting, especially if symptoms recur.
