[A scale for the quantitative evaluation of male copulative function (the MCF scale)].

A scale of total quantitation of male copulative function (MCF) is offered to facilitate the diagnosis and monitoring of MCF abnormalities, control of MCF correction. The scale is based on normal values provided by statistical data on sexual activity of males and its age-related changes. The patient is asked to answer 13 questions of the questionnaire listed under the numbers I-XIII. Each question has 6 variants of answer having the score 0 to 5. The patient is to choose one variant and write down his choice. Such MCF scale is able to identify both sexual disorder and defects in components of the copulative cycle. The scale was applied 89 times to study sexual function of 68 males aged 24-77 years. The scale findings and those of a comprehensive clinical examination coincided. The scale was found useful in evaluation of male copulative function as a whole and by components, for analysis of the detected disorders, differentiation between psychogenic factor and primarily organic one, for ascertaining attitude of the patient to his sexual dysfunction.
