Dr. Leo J. Latz was one of the pioneers of the "rhythm" method of birth control, now often called natural family planning. The Rhythm method asserts that women are only fertile for five or six days of their menstrual cycle, and so it is unlikely for a woman to get pregnant outside of those days, even without material methods of birth control. His book went through twenty-six editions.
The Rhythm Method is the only method of birth control which received the official approval of the Catholic Church, having been approved by Pope Pius XII in 1951. In 1955, a survey of Catholic women found that over 65% of the women surveyed said they used the Rhythm method.
In 1934, Latz, a devout Catholic, was fired from his position at Loyola University, most likely over his involvment with the cause of Rhythm.
