Male Sexual Formula Test

In about two minutes, the Male Sexual Formula Test asks 10 questions about desire, arousal, intercourse, ejaculation, emotional experience, and the timing of sexual difficulties. Your result provides a structured profile of sexual functioning, supporting personal reflection and helping you identify experiences or areas you may want to understand more closely.

How the Scales are Structured

Duration of DysfunctionDoD

Measures how long ago sexual-sphere difficulties first appeared to capture the time course of the concern.

example score2/4

2/4Recent onsetexample score

0 – 2Recent onset

3 – 4Long-standing

A score of 2 falls in the Recent onset range, suggesting the difficulties began relatively recently rather than being long-standing.

Third TriadTT

Assesses how a man subjectively evaluates and reflects on his past sexual activity and experience.

example score5/12

5/12Lowexample score

0 – 8Low

9 – 11Elevated

12High

A score of 5 falls in the Low range, suggesting relatively limited or less pronounced subjective emphasis on evaluating past sexual experiences.

Second TriadST

Measures objective parameters of sexual act execution, reflecting the quality and characteristics of the sexual encounter.

example score10/12

10/12Higher objective executionexample score

0 – 8Lower objective execution

9 – 12Higher objective execution

A score of 10 falls in the higher objective execution range, suggesting generally strong objective characteristics of the sexual encounter on this scale.

First TriadFT

Measures arousal and preparatory readiness in the early stages of the copulatory cycle before intercourse.

example score3/12

3/12Lowexample score

0 – 8Low

9 – 11Typical

12High

A score of 3 falls in the Low range, suggesting relatively reduced arousal and preparatory readiness in the pre-intercourse phase compared with higher scores on this scale.

Overall (Prognostic) IndexOI

This scale summarizes overall sexual functioning across all MSF triads as a single prognostic index.

example score12/40

12/40Lower overall functioningexample score

0 – 29Lower overall functioning

30 – 40Higher overall functioning

A score of 12 falls in the lower overall functioning range, suggesting reduced cumulative sexual functioning across the assessed domains compared with higher scores.

WHAT THE TEST MEASURES

Male Sexual Formula Test - Description and methodology of the test

sexology

For a man trying to make sense of sexual concerns, this Male Sexual Formula Test offers an organized way to see which experiences fit together rather than reducing them to a single yes-or-no judgment. This male sexual functioning test examines how the questionnaire's answers relate within the result, helping organize concerns into a pattern. It can support personal reflection, pattern recognition, and decisions about which experiences deserve closer attention.

What This Assessment Explores

The questionnaire follows experience from anticipation to outcome. It examines desire, initiative, confidence before intercourse, erection, penetration, ejaculation, mood afterward, satisfaction, and whether difficulties are current or longstanding. This questionnaire is a male sexual formula questionnaire in which subjective experience is interpreted alongside functional responses; the result is therefore read as a pattern rather than an isolated symptom.

The displayed dimensions are interpreted as follows:

Duration of Dysfunction (0-4) shows when problems began: Recent onset 0-2; Long-standing 3-4.
First Triad (0-12) covers arousal and preparation: Low 0-8; Typical 9-11; High 12-12.
Second Triad (0-12) covers objective sexual-contact characteristics: Lower objective execution 0-8; Higher objective execution 9-12.
Third Triad (0-12) covers subjective appraisal: Low 0-8; Elevated 9-11; High 12-12.
Overall (Prognostic) Index (0-40) reflects total functioning across the triads: Lower overall functioning 0-29; Higher overall functioning 30-40.

Methodology and Scientific Basis

Self-report is the method: each item describes a situation or function and offers ordered choices about frequency, ability, timing, emotion, or perceived success. The options are item-specific rather than a universal rating scale, and the answer pattern produces the displayed profile.

The questionnaire is conceptually consistent with Male Sexual Formula (Vasilchenko, 1977), a published model with a comparable triad organization. This online version has no documented version-specific validation.

The result displays separate scores for the timing measure, the three triads, and the overall index; points per answer should not be inferred because the item-level conversion is not documented. Comparing the triads with the overall index can show whether the displayed pattern is concentrated in one stage or distributed across several, while the timing measure adds context about onset.

The result bands are descriptive, not population norms or clinical thresholds. A male sexual health assessment should be read alongside symptoms, physical health, relationships, and personal goals; memory, candour, self-awareness, current health, and relationship circumstances can affect responses.
