Relaxin, a heterodimer protein with a molecular weight of 6000, is secreted by the corpus luteum and placenta during pregnancy (1–2). It is structurally related to insulin and insulin-like growth factor I, and its principal physiologic role seems to be fostering the growth and remodeling of the uterus. Relaxin also loosens the pelvic ligaments and ripens the uterine cervix in preparation for parturition (3).
