037 Semen Quality Impairment is Associated with Sexual Dysfunction According to its Severity

Abstract

STUDY QUESTION: Is sexual dysfunction associated with severity of semen quality impairment in men with couple infertility?SUMMARY ANSWER: In males of infertile couples the prevalence of erectile dysfunction (ED) increases as a function of semen quality impairment severity.WHAT IS KNOWN ALREADY: Infertile men are at a higher risk for sexual dysfunction, psychopathological and general health disorders. However, it has never been systematically investigated if these problems are associated with severity of semen quality impairment.STUDY DESIGN, SIZE, DURATION: Cross-sectional analysis of a first-time evaluation of 448 males of infertile couples attending an outpatient clinic from September 2010 to November 2015. In addition, 74 age-matched healthy, fertile men from an ultrasound study on male fertility were studied for comparison.PARTICIPANTS/MATERIALS, SETTING, METHODS: All subjects underwent a complete physical, biochemical, scrotal and flaccid penile colour-Doppler ultrasound evaluation and semen analysis. Patients had already undergone at least one semen analysis; therefore, the majority were aware of their sperm quality before taking part in the study. Validated tools, such as the International Index of Sexual Function-15 (IIEF-15), Premature Ejaculation Diagnostic Tool (PEDT), Middlesex Hospital Questionnaire (MHQ), National Institutes of HealthChronic Prostatitis Symptom Index (NIH-CPSI), International Prostate Symptom Score and Chronic Disease Score (CDS), were used to evaluate, respectively, sexual dysfunction, premature ejaculation (PE), psychopathological traits, prostatitis-like symptoms, lower urinary tract symptoms and general health status. MAIN RESULTS AND THE ROLE OF CHANCE:Among men with couple infertility, 96 showed azoospermia (Group #1), 245 at least one sperm abnormality (Group #2) and 107 normozoospermia (Group #3). Fertile men were considered as a control group (Group #4). After adjusting for age, we observed a higher prevalence of ED (IIEF-15-erectile function domain score <26) (18.3% versus 0%; P = 0.006) and PE (PEDT score >8) (12.9% versus 4.1%; P = 0.036) in males of infertile couples compared with fertile men. The ED prevalence increases as a function of semen quality impairment severity (P < 0.0001), even after adjusting for confounders (age, CDS, MHQ and NIH-CPSI total score), despite similar hormonal, glyco-metabolic and penile vascular status. Compared to fertile men, all three groups of males with couple infertility showed a poorer erectile function, associated with an overall psychopathological burden (MHQ total score), particularly with somatized anxiety (MHQ-S). Azoospermic men showed the worst erectile function and general health: in this group, erectile function was negatively associated not only with psychopathological disturbances (MHQ total and MHQ-S scores; P < 0.0001) but also with a less healthy phenotype (higher CDS; P = 0.015). In addition, azoospermic men reported higher PE prevalence and lower sexual desire and orgasmic function when compared to fertile men (all P <...
