I've been holding off on going on TRT for reasons, but one of them is the fear of testicular shrinkage. I already have small testes, in my opinion, and am concern of how much smaller they can get. What is the likelyhood of shrinkage and how much in percentage can I expect. I understand everything is diff for everyone, just trying to get an overall idea.

Last year my car started idling high and strangely the ac would not work. It blew air, but not cold. I mention the A/C because both always occur together. Took it to shop where they thought it was and egr issue, then they said IACV. I also noticed during the winter that it rarely occured, now with hotter days and summer coming up, it is happening again. Any ideas or suggestions?
