Does 70% alcohol kill sperm?

Please clarify. I do not understand the question. Are you asking if using alcohol post coitus will kill sperm and prevent pregnancy? If you are asking this the answer is not very effectively. Alcohol would not reach the internal cervix or uterus to kill any sperm swimming there. Topical alcohol is not a form of birth control.
