HUMAN SEXUAL FUNCTION: NEW INTERPRETATIONS OF HELÍ ALZATE’S MODEL

Abstract

The sexual function model by Helí Alzate (1987) remains relevant due to its explanatory capacity regarding human sexuality and sexual dysfunctions. It proposes three planes: psychic, somatic, and behavioral (or external). Additionally, it describes five phases: appetitive (or desire), relational, stimulatory, excitatory, and orgasmic.
The appetitive phase is related to sexual desire and motivation. The relational phase involves interaction with others, with oneself, and the construction of a sexual bond. In the stimulatory phase, sensory and psychic stimuli are activated, enhancing arousal. The excitatory phase intensifies physiological and emotional responses, and the orgasmic phase culminates in orgasm and resolution.
The psychic plane is essential, as conscious sexual function cannot occur without its activation. The somatic plane includes physiological responses such as genital arousal, while the behavioral plane focuses on physical interaction with a partner or oneself.
This model helps differentiate real sexual dysfunctions from those that are not, facilitating diagnosis and treatment. Its review reaffirms its value in understanding sexuality and its applicability in clinical practice, contributing to improved sexual health care.
