Likely standard issue shrinkage.
However...
Before I was on HRT I had occasional pain in the inguinal canals and my testicles. When I started HRT the pain got worse. Eventually the pain got so bad I has poping opiates like candy.
Eventually I was able to get some diagnostic tests done and after an ultrasound it was determined I had cysts and deformities of the testicles. My doctor agreed with me when I said I wanted them out, so he refered me to a surgeon to have them removed.
However....
The doctor he referd me to said in no uncertain terms and exactly "we do not serve transgender clients in this office." I didn't get that information until the day before my apointment.
It took a number of months to finaly find a Urologist who was willing to do the operation that was also familiar with how to properly do an orchidectomy for a trans woman.
The kick in the teeth above and beyond the pain I was forced to endure for many extra months was that my doctor had refered anouther patient who had the exact same issues as I did who got an orchi with in 2 weeks of his initial diagnosis. So if I was a normal "male" i would have gotten my surgery much sooner. I hate how we are discriminated against.
Anyways....
The reason I brought this up is that if they continue to be in constant unremiting pain that alone is proper medical reason for their removal. Might become a hassle finding a surgeon who will do the job and can do it without messing up a future srs.
(on an aside note, I have had Dr Nguyen in Lake Osswego look at the scar my orchi surgeon left behind and the doc N said that the scar was in a wierd place, and he had never seen such placement of an orchi scar but it would not be an impediment to my future srs and the scar placement was a very good idea. So making sure the surgeon who does any orchi for you knows how to properly place the incision is a good plan.)
