Barrier methods of contraception are generally more accessible than many other forms of contraception, as they do not require a prescription. Barrier methods have high failure rates with typical use, so are not recommended as the sole method of contraception if either partner is highly fertile, or if unintended pregnancy would pose medical or psychological harm.
