And 5th, I have no idea how long sperm remains viable in the prostate, but I imagine that you would have to ultrasound your balls regularly or end up with live swimmers in a very unpredictable way. I'd imagine you'd destroy them and maybe their precursors, then have protected sex for 2-3 times to get rid of the viable sperm and only after that end up with 1-2 weeks of infertility.

The links to data in other comments suggests a treatment would take about 2 weeks to become effective (rid the system of existing viable sperm), then last approximately 6 months. Although, if you look at the graphs/numbers it seems there still are a small number of motile sperm (looks to me like approximately 50% reduction in count with 20% motility). Seems like it doesn't completely eliminate the possibility of pregnancy.
