In the 1940s, Spock initially favored circumcision of males performed within a few days of birth. However, in 1989, in an article for Redbook magazine, he stated that "circumcision of males is traumatic, painful, and of questionable value."[11] He received the first Human Rights Award from the International Symposium on Circumcision (ISC) in 1991 and was quoted saying "My own preference, if I had the good fortune to have another son, would be to leave his little penis alone".[12]
