hi sir i feel your worry and i respect your feelings of that..but first you should be confirmed if have hiv or not thraugh pcr test ..if pcr test results less than 50 that means you are negative ..if results between 50 - 5000 you should repeat tests ..if results more than 5000 means you are positive..you should also begin antiviral therapy as soon as possible as if it taken early the results will be good about your querry of transmission sexual contact and expose to blood thraugh percutanous injury is the main method..you want to have child but you should avoid any unprotected sex with your wife to protect her the solution in your problem is thraugh in vitro fertilization (IVF) to avoid direct contact with your wife and avoid transmission of infection and that will help you alot you are great man wish you happy life
