WASHINGTON (AP) — The roadside bomb that exploded outside Andrew Robinson’s Humvee in Iraq six years ago broke the Marine staff sergeant’s neck and left him without use of his legs. It also cast doubt on his ability to father a child, a gnawing emotional wound for a then-23-year-old who had planned to start a family with his wife of less than two years.

The catastrophic spinal cord injury meant the couple’s best hope for children was in vitro fertilization, an expensive and time-consuming medical procedure whose cost isn’t covered by the Department of Veterans Affairs. Robinson and his wife were forced to pay out of pocket, with help from a doctor’s discount and drugs donated by other patients.
