Abstract
Contraceptive use is wide-spread in the world with 62% of reproductive-aged women currently using a contraceptive method (1). Many preference-sensitive healthcare decisions, contraceptive methods have both desirable and undesirable attributes which require the patient to make trade-offs between potential benefits and disadvantages of options. However, many women lack knowledge or support for contraceptive decision-making or have unrealistic expectations, unclear values, or social pressures that can complicate decisions (1, 2). Many women remain uninformed about highly effective contraceptive methods such as intrauterine devices (IUDs) and implants and use remains low compared to oral contraceptive pills and condoms; methods that have lower rates of effectiveness (3, 4). Effective contraceptive counseling should assist women in identifying important method attributes. This, in turn, can help women choose the contraceptive method most consistent with her preferences which may lead to improved continuation and satisfaction (5, 6). Hormonal contraception is not only used as contraception but also as a symptomatic treatment of various endocrine disorders such as polycystic ovarian syndrome and endometriosis. Among infertile patients, pretreatment with oral contraceptives is often used for programming the cycle in anovulatory women prior to ovulation induction and prior to ovarian stimulation for IVF .
