When anesthesia was developed, it was for many decades routinely withheld from women giving birth, since women were "supposed" to suffer. One of the few societies to take a contrary view was the Huichol tribe in Mexico. The Huichol believed that the pain of childbirth should be shared, so the mother would hold on to a string tied to her husband's testicles. With each painful contraction, she would give the string a yank so that the man could share the burden. Surely if such a mechanism were more widespread, injuries in childbirth would garner more attention.
