Highly effective methods include: * Oral Contraceptive, either combined or progestogen alone * Injectable progestogen * Implants of levonorgestrel * Estrogenic vaginal ring * Percutaneous contraceptive patches * Intrauterine device or intrauterine system with a failure rate of less than 1% per year * Male partner sterilisation (vasectomy with documentation of azoospermia) prior to the female subject's entry into the study, and this male is the sole partner for that subject. For this definition, "documented" refers to the outcome of the investigator's/designee's medical examination of the subject or review of the subject's medical history for study eligibility, as obtained via a verbal interview with the subject or from the subject's medical records * Double barrier method: condom and an occlusive cap(diaphragm or cervical/vault caps) with a vaginal spermicidal agent (foam/gel/film/cream/suppository), including nonoxynol-9
