I had a male boa that I had purchased as a female. I had this animal for a few months and had not paid a lot of attention to his/her plumbing up until this point....just assuming that it was a female. It was a two year old. One day, I was rearranging enclosures and put this animal in with a female in her huge vision enclosure. At that time she was on Aspen. Nothing eventful happened and the next day I noticed some unusual activity that looked like courting - surprise, surprise!!! Upon closer inspection, I saw an exposed hemipene. I took “him” immediately and put him in some water to soak because the Aspen was stuck to it. Later I put him in the sink with some tweezers and cleaned it the best I could. Then I put him on very sloppy wet paper for the night and made a vet appointment first thing the next morning. At the vet’s we sedated him and cleaned and flushed him over and over. The vet pushed it back in very carefully and put in a couple of sutures on the side to hold it. When I went back to have the stitches removed, the hemipene came back out. So, we sedated him and did the same thing over again, but this time he pulled it all the way out and sure enough there were little bits of Aspen still way down in there. This time when he put the hemipene back in, it stayed after the stitches were removed. That boa went on to father a litter of babies. The vet told me that keeping the tissue clean and moist was the key to it working. If it had started dying, he would have had to amputate it. Now I use newspaper substrate.
I forgot about the honey thing, but that is great advise. We have used honey on horse wounds for years and it works wonders for healing without scarring.
