I try to answer the Questions but like i sad it’s not easy for me with my bad English:(
For all the tests that has been made in Muenster i don’t have to pay anything for it because it’s get paid by the health insurence wich everyone here in Germany has. They are tested for AR silencing with a sperm sample.
The result of the sizing of CAG triplet region of exon 1 of androgen receptor are that i have 25 tripple repeats wich means a partial androgen insensitivity. Prof.Zitzmann and the other Doctors in Muenster knows a lot of PFS and they treat 2-3 patients per month and i think that they have patients from all over Europe and specially the Prof.Zitzmann travels a lot to the USA and Italy to help by the research of PFS.
I also found something about Prof.Zitzmann here in the Forum.
