I was diagnosed with ADHD in 2003, so I've lived with and known about it for a long time, and something I've noticed since I stopped taking my cyproterone to get some usable sperm going is the stark difference in my ADHD symptoms. Everyone in my family has been diagnosed, and my sister has always said it presented differently for her because girl than it did for my brother and I, and I didn't notice a difference when I started on hormones, but now that I'm not taking androgen blockers, so boy juice is back in my system, the difference should have been obvious.
The big one is that I can't sit down and read anymore. My wife got me a kobo for christmas and it got me so much back into reading like I hadn't been since puberty. I'm currently at 47 books read this year, but the amount of time I spend reading in a day has plummeted in the last month once the testosterone effects really kicked back in. I've been going with 70+ pages a day (318 page record whoop) 3-5 days a week all year and now it's been 2 weeks since I started my last book and I'm only 72 pages into it.
I'm not doing as well at work either. I have 5 tasks to do A B and C can all be done, but they need to be in sequence, so I'll start A, spot a tool or bit of material I need for D, and start carrying it around until I spot something for E and put down what I'm carrying and pick that up, then realize I was starting on A and I've been wandering around with materials for other tasks for 15 minutes.
The lack of ability to focus on one thing is suddenly going strong again, and I doubt this is unique to me, but I figured I'd share my experience with ADHD symptoms being effected by HRT, but bodies are wild. I never would have thought about it as something that could be affected until my sister asked about it.
