Nick,
Some things that may help your doctor make the choices you want, instead of the things he wants:
request sperm testing, and tell him that you are trying to get your girlfriend/wife/mother pregnant.
also stating that you are afraid of the exposure of the patches to said breeder.
You can simply state: I don't have the financial ability to use the patch, because...
If things get kind of nasty, and as a last resort you can bring up the question about his insistence of using the patch, and does this have anything to do with a pharmacutical sales rep buying him off to sell these overpriced patches. sometimes when you question a person's ethics, they will back off from their opinion... sometimes they may just kick you out of their office too.
Standing up for yourself is the theme of this, because the doctor doesn't have to live with a limp dick and night sweats.
