When we briefly touched on "wrongful life" or "wrongful birth" causes of action in law school, the general trend seemed to be to not allow them, although I think there may have been one or two jurisdictions that did recognize them. A quick google search (it's late) didn't give me a definitive answer.
It usually comes up in one of three ways; a vasectomy that didn't take, a botched abortion, or a doctor's negligence in not diagnosing some kind of prenatal defect in the child in time for the pregnancy to be terminated. Hypothetically, in a jurisdiction where wrongful birth might be recognized, I can see a pharmacist's refusal to fill a doctor written prescription could be the kind of wrongful conduct that might give rise to liability.
