I agree with the previous posts... you need to discuss this all with your doctor.
But as long as you are using an egg and sperm from a non-infected HIV donor... the risk would be zero.
But definitely discuss all your options with your doctor. There are many modern day drugs that can reduce the risk of transmission of HIV to your baby to less that 2%... and that is with YOU getting pregnant on your own with artificial insemination from a partner that is HIV negative and planning ahead.
Here is a site you can read about that...
HIV, pregnancy, mothers and babies
Best of luck! :)
