Quizplus · Accepted Answer

Relaxin is the hormone that causes pelvic ligaments and the pubic symphysis to relax, widen, and become more flexible during pregnancy. Estrogen and progesterone also play important roles in pregnancy, but they do not specifically cause relaxation of the pelvic ligaments and pubic symphysis. LH is responsible for ovulation, not pregnancy-related changes in the pelvic region.
