“…In the 1990s and early 2000s, the U.S. saw a dramatic increase in the number of available HCs, from the initial approvals of implantable and injectable contraceptives (referred to as long-acting reversible contraceptives, or LARC) to the introduction of the patch and the ring [3,5]. In this new context, contraceptive selection is related to convenience, cost, side effects, peer utilization, and awareness of method [6,7], and many women try more than one HC route in their lifetime [3]. Yet, studies of reasons for HC use are relatively limited, and mainly concern reasons for choosing one HC type over another in the context of family planning [6,7], as opposed to clinical indication(s) for use, and most focus on oral contraceptive use.…”
