Analysis

The IIEF is a tool designed to assess erectile function and sexual satisfaction in men. It includes questions covering various aspects of erectile function, such as the ability to achieve and maintain an erection, sexual desire, pleasure during sexual activity, and overall satisfaction with sexual life.

Aim

The main aim of the IIEF is to:
Assess erectile function: Measure men’s ability to achieve and maintain an erection sufficient for satisfactory sexual activity.
Evaluate sexual desire and satisfaction: Examine sexual desire, pleasure, and overall satisfaction with sexual life.
Support diagnosis and monitoring: Provide data that assist in diagnosing erectile dysfunction and in monitoring the effectiveness of therapeutic interventions.
Assist in the development of treatment strategies: Contribute to the development of strategies and therapies aimed at improving erectile function and sexual satisfaction.

Calibration

The calibration of the IIEF includes:
Categorization of Responses: Participants answer questions covering aspects of erectile function, sexual desire, pleasure, and satisfaction, using response scales such as often, rarely, never, etc.
Total Score: A total score is calculated for each domain of erectile function (e.g., erection, desire, pleasure) as well as an overall score reflecting total erectile and sexual functioning.
Analysis of Results: The relationship is examined between levels of erectile function and other parameters, such as physiological and psychological conditions, as well as the impact of therapeutic interventions.
