Huston's work with the International Planned Parenthood Federation led to her research for, and publication of, a third book, Motherhood By Choice: Pioneers in Women's Health (The Feminist Press of the City University of New York, 1992).  The book recounts the experiences of early family planners in twelve countries: the Dominican Republic, Norway/Sweden, Sri Lanka, Singapore, Egypt, Thailand, Tunisia, Bangladesh, New Zealand, Ghana, Japan and Mali.

The text was also published in London under the title The Right to Choose: Pioneers in Women's Health & Planning (Earthscan Publications, in association with International Planned Parenthood Federation, 1992).
