Thanks for your query.
I read your query and I understand your concerns.
High FSH and low testesterone means you have primary testicular failure. I dont see great chances of conception. Any way undergo needle biopsy
to confirm presence of sperms.
If no sperms are found I am afraid you have to go for donor semen treatment for your wife.
I hope I answered your query. I will be available for any followup queries you have.
