The average distention of the symphysis during labor was mm for those without pelvic pain and mm for those with a history of pelvic pain during pregnancy (p = ). A modulator of arterial compliance and cardiac output during pregnancy, relaxin also serves to relax the pelvic ligaments and contribute to softening of the cartilage of the pubic symphysis for preparation of the birth canal for delivery. AAuthor: Aaron J. Seidman, Marco A. Siccardi. Marked separation of the pubic symphysis has been shown to occur in pregnant deermice (Peromyscus maniculatus bairdii and P. m. gracilis) and in immature deermice following treatment with relaxin.A pubic separation of approximately mm on the day of mating remained essentially unchanged for the first 10 days of gestation.

Review of the structure of the symphysis pubis, based on my extensive study of the pelvic joints ('31) shows changes from age, function, pregnancy hormones and stress of parturition. “The pubic symphysis pain is most likely caused by pelvic subluxation. The pelvis is a ring, so if one of the joints misaligns and is fixated, the others will undergo more and unusual stresses. The production of the hormone relaxin during pregnancy loosens the normally taught ligaments of the sacroiliac joints, allowing them to subluxate more. Relaxin promotes the relaxation, widening, and increased flexibility of the pelvic ligaments and pubic symphysis. What role does oxytocin play in promoting labor? Oxytocin stimulates the uterus to contract. During last few weeks of pregnancy. the fetus secretes cortisol.

During pregnancy, high progesterone and relaxin levels produce physiological ligament relaxation on the pelvis. Therefore, moderate pubic symphysis and sacroiliac joints relaxing provide birth. As early as Snelling 2 wrote that "relaxation of the pelvic articulations becomes apparent suddenly after parturition or gradually during pregnancy, permitting a degree of mobility which hinders locomotion and gives rise to the most alarming and distressing sensations."
