How safe is the current state of assisted reproductive technology?

Very safe: Art has been used in the United States since 1981 to help women become pregnant, most commonly through the transfer of fertilized human eggs into a woman’s uterus (in vitro fertilization). Although the use of art is still relatively rare as compared to the potential demand, its use has doubled over the past decade. Today, over 1% of all infants born in the United States every year are conceived us.
