Religious adherents vary widely in their views on birth control (also known as contraception). This can be true even between different branches of one faith, as in the case of Judaism and Christianity. Some religious believers find that their own opinions of the use of birth control differ from the beliefs espoused by the leaders of their faith, and many grapple with the ethical dilemma of what is conceived as "correct action" according to their faith, versus personal circumstance, reason, and choice.
