Its current definition, together with the most used diagnostic tools, does not include nonvaginal sexual intercourse such as anal sex, self\u2010masturbation and\/or partnered\u2010masturbation, and other forms of sexual stimulation. However, diagnostic psychometry currently available is exclusively evaluating PE in the vaginal coitus.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objectives<\/jats:title><jats:p>To validate a new tool, the masturbatory premature ejaculation diagnostic tool (MPEDT), by assessing the control over ejaculation and its psychological effects during self\u2010masturbation, rather than heterosexual vaginal intercourse.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and methods<\/jats:title><jats:p>We studied 135 male patients aging from 18 to 40 years seeking medical care for PE in the Infertility and Sexual Medicine Department from June to September 2020. All the participants were asked to fill the premature ejaculation diagnostic tool PEDT and MPEDT questionnaires to estimate the PE symptoms during, respectively, intercourse and self\u2010masturbation. The reliability\/validity, the factor analysis of the tool, and the diagnostic sensitivity\/specificity of MPEDT were calculated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The overall Cronbach alpha was 0.884. In our adjusted model, both root mean square error of approximation (RMSEA) and standardized root mean square residual (SRMR) were lower than 0.08, while goodness of fit index, adjusted goodness of fit index, non\u2010normed fit index (NNFI), and comparative fit index (CFI) were higher than 0.9. The area under the ROC curve (AUC) is 0.943 \u00b1 0.015. The results suggest MPEDT points being \u22645 as \u201cnormal,\u201d \u22657 as \u201cPE during self\u2010masturbation,\u201d and 6 as \u201csuspected PE,\u201d with the sensitivity of 91.9% and specificity of 88.1%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>An efficient diagnostic psychometric tool is needed for the individuals who, based on the impaired control over ejaculation during self\u2010masturbation, may also suffer from PE during partnered intercourse.
