Effect of perineal body tone on sexual dysfunctions in young nulliparous women ; Efeito do tônus do corpo perineal nas disfunções sexuais em mulheres jovens nulíparas

Objective: to evaluate the tone of the perineal body in young nulliparous women and correlate it with sexual functions and the presence of sexual dysfunction. Method: a descriptive, observational, cross-sectional study was carried out using a convenience sample including nulliparous young adult women. The evaluation of the participants consisted of the application of the socio-clinical questionnaires, Pelvic Organ Prolaps / Urinary Incontinence Sexual Questionnaire (PISQ-12), Female Sexual Function Index (FSFI) and physical examination of the tone of the perineal body. The data were analyzed using the Statistical Package for the Social Sciences (SPSS®), version 23, adopting a significance level of 5%. Results: 77 young nulliparous women (21.68 ± 2.94 years) participated, of which 77, 92% had an active sexual life and 66.03% had normal tone of the perineal body. Among the tonic changes, increased tone predominated (33.76%). There was a high prevalence of sexual dysfunction (87.01%) according to the FSFI (23.38 ± 7.21) with greater complaints of dyspareunia. Women with increased tone had greater sexual dysfunction in relation to desire and subjective stimulation (p=0.04), excitement (p=0.01), satisfaction (p=0.04) and pain or discomfort (p=0.03). There was an inverse correlation between the presence of increased tone and the FSFI domains desire and subjective stimulus (R= - 0.56) and excitement (R= - 0.34) and a direct correlation for pain or discomfort (R= 0.30). Conclusion: increased perineal body tone worsens sexual function in young nulliparous women. ; Objetivo: avaliar o tônus do corpo perineal em mulheres jovens nulíparas e correlacionar com as funções sexuais e a presença de disfunção sexual.
