In the years since, Harrison has become more outspoken.
He calls himself an "abortionist" and says, "I am destroying life."
But he also feels he's giving life: He calls his patients "born again."
"When you end what the woman considers a disastrous pregnancy, she has literally been given her life back," he says.
Before giving up obstetrics in 1991, Harrison delivered 6,000 babies. Childbirth, he says, should be joyous; a woman should never consider it a punishment or an obligation.
"We try to make sure she doesn't ever feel guilty," he says, "for what she feels she has to do."
