The doctors that cared for him at the hospital said it was clear from blood work that the testosterone was to blame. I’m not exactly sure what it showed and why they said that. It’s hard to remember a lot of it without the records in front of me. I was just under the impression that some men can’t take it because of having some of the more serious side effects and that the reason things got so bad was from the doctor being negligent. I know other men on it that have been fine. We’ve had lawyers contact us that are mass suing the companies that make it, but we’re not really interested in that. Seems like it helps a lot of people. Unfortunately, my husband is one of the lucky few to deal with the worst risks.
