Only the American version has been seen. Its history has been deduced from the notes to an entry in Le Dictionnaire for the gay film of 1977, Des jeunes gens pour messieurs, AMT Productions (Anne-Marie Tensi), directed by Olivier Marc (Anne-Marie Tensi). The note reads: "Le nom au scénario avait déjà été utilisé par AMT Productions pour la réalisation du porno italien présenté comme français, Check-up érotique." There is no entry for this hetero film in Le Dictionnaire. Nor is there in Luce Rossa or DizionHard. Its mixed parentage has evidently led to it falling through the cracks.
From the imdb entry for Check-up érotique, it seems that the French release used some obviously invented names and, from the version viewed it seems that the American version invented some slightly different ones.
The cast listed on imdb are: Léopold Beaudard, Marceline Ninfot, Willie Jacquette, Gertrude Cliteau. Ninfot, Cliteau?
The surname Cliteau is used again in the American credits, which are: "Starring Nina Cliteau, Marcie Mendome, Sophie Stiguer, Raoul Colombo, Lou Belford; with Gina Volare, Nancy Ames, Karen Nelson, Bobby Krivit, Sam Silver. Written, produced and directed by Antonio Fabrizana."
The film consists of a series of vignettes where women ring up the doctor who prescribes a visit from a well-endowed male who is the 'medicine'. This scenario matches the title Check-up érotique.
The website Sinerama suggests that Aldo Fabriziana is an alias of Renato Polselli.
