Eleven young adult male subjects were each recorded for three sessions of masturbation to orgasm. Electrical signals from an anal pressure probe were automatically digitized by computer.

Orgasmic contractions were easily distinguished from voluntary contractions by the steadily increasing intervals and complete muscle relaxation between orgasmic contractions.

At orgasm each subject produced a characteristic series of contractions starting abruptly at an intercontraction interval of about 0.

Pressure amplitude, representing the force of contractions, increased from the beginning of the regular series to a maximum at the seventh or eighth contraction.

Area under the pressure curve, reflecting muscular exertion during contraction, generally increased throughout the regular series. Each man's pattern of contractions was very similar from one session to the next and distinguished his records from others'.
