The film was released in Italian cinemas by Florida Cinematografica on 10 March 1971.
Piero Virgintino on La Gazzetta del Mezzogiorno wrote: "glossily decked out, as much as visually sterile, the film is a sexy fotoromanzo [...] with a few hints of crude humor". Stampa Seras critic Achille Valdata complained about the film's use of the Don Juan character, noting "it's disappointing [...] that such a lively and compelling figure [...] has to be reduced to such a kind of soulless puppet, of little prestige and nobility, possessing an amatory vocation that does not transcend the limits of the ordinary."
