Marital sexual dysfunction: ejaculation disturbances.

The three clinically encountered disturbances of the male orgasmic phase--that is, premature ejaculation, inability to ejaculate, and retrograde ejaculation--are discussed. The problem of defining premature ejaculation is explained and the possible pathogenic mechanisms of its origin are reviewed. The classic premature ejaculator is described. Also included are an elaboration of the newer therapeutic approaches to the problem and a suggested clinical protocol for screening patients. The other two, less common dysfunctions are briefly discussed.
