Check out a guy named Ryan Ballow (I'm pretty sure) on Youtube. He has a channel named Cortex Labs and does a lot of content on TRT and specifically sexual function optimization/recovery for guys who suffered from PFS or PFS-like symptoms.
I think a lot of his ideas around that are good, specifically using DHT to recover from PFS. I would add neurosteroids, especially Pregnenolone since 5-alpha reductase, the enzyme blocked by Finasteride and other such meds, is responsible not only for the conversion of Testosterone into DHT but also of Progesterone into Allopregnanolone among others, making it one of the most crucial enzymes in male physiology. To be clear, Progesterone is converted directly from Pregnenolone, which is why I mention the latter.
I'm pretty sure he does personal consulting; it's probably not cheap but if you can afford it, I would say there's a good chance it'll be worth it.
If you can't, I'd say get your hands on some DHT gel, Pregnenolone/DHEA (pharma compounded if you can, if not I would use the brand Nootropics Depot. They have third party testing COAs I'm pretty sure and in my opinion are one of the very, very few trustworthy supplement companies in the US), and make sure you have a Testosterone base because DHT will shut you down.
Then just experiment with combinations of those. I think the most promising path for PFS symptoms is almost certainly hormone supplementation/optimization.
