David Mrazek said that Sandfort's study presented in The Sexual Aspects of Paedophile Relations suffered from sample bias. He stated that, although Sandfort stated that the findings were not generalizable, he still sought to generalize the results.

Male Intergenerational Intimacy Male Intergenerational Intimacy: Historical, Sociopsychological and Legal Perspectives (1991) is a book by Sandfort that compiles 16 research articles and three commentaries on homosexual intergenerational relationships.

Reception Researcher Gary Klein said that the title of Male Intergenerational Intimacy was confounding, since the book did not examine relationships between adult men of different generations. He criticized the book's lack of an index and said that the book lived up to its subtitle, as, he stated, it did provide a multifaceted analysis of pedophilia. Klein stated that, for all but one article, "each contributor provided a comprehensive set of research notes which would be of immense help to anyone doing extensive research on pedophilia".
