Synergy ExplorersThis French book about marital continence, Art D’Aimer, triggered a tempest among French Catholics when it appeared in 1949. The Synergy-like practice was also known as the étreinte réservée (reserved embrace)

Paul Chanson proposed conjugal continence as a birth control solution for couples with legitimate reasons for limiting births. He also touted it as a way to promote sexual harmony between spouses. The Catholic Church soon caused the book to be removed from circulation and suppressed its publication and translation.
