Ferrari's disappointment at having to leave the hospital was offset in 1939, when she was finally made a full professor, receiving the title "Profesor Extraordinario" of the Obstetrics Faculty.[25] Throughout the 1940s she continued her education, traveling to Cuba, New York, Pennsylvania, Peru, and Puerto Rico, publishing her research in a variety of journals.[26] In 1946 she resigned as president of the Argentina Federation of University Women,[20] but continued to represent the organization at conferences, like the Primer Congreso Interamericano de Mujeres, which she attended in Guatemala City in 1947.[27]
