The most effective form of reversible birth control after abstinence is an intra-uterine device (IUD), closely followed by hormonal contraception, which can come in the form of a pill, patch, implant, or insertable ring. IUDs have a failure rate of less than one percent in most controlled studies.
Natural methods of birth control are always preferable to chemically based agents such as spermicides, contraceptive patches and IUDs which emit synthetic hormones, or the contraceptive pill which decimates the balance of gut flora and can lead to autoimmune disease in the mother and any children born later.
