I know sperm banks offer washed sperm. Sometimes that is the hardest part of getting pregnant. Your next step is to figure out what approach you want to take. At the risk of saying things that are obvious, you should make sure your donor has been tested for HIV and hepatitis and that he carries no obvious genetic traits that might put your child in danger. Your next decision is whether you want to try to inseminate using fresh or frozen sperm.
Fresh sperm is always best.
The sperm counts are highest and the little guys seem to travel inside you more easily when they have not been frozen. If you have this option, you should track your ovulation cycle for a couple of months to know fairly accurately when you are going to ovulate. Then you either get your donor to Orlando or get yourself to Pittsburgh. The ovulation kits sold in pharmacies are pretty reliable. A smaller syringe might afford a little more control.
