To assess the evolution of sexual dysfunctions among young males after an average of 15 months follow-up to determine the predictive factors for this evolution and the characteristics differentiating young males who continue reporting a sexual dysfunction from those who do not.


We conducted a prospective cohort study in two Swiss military recruitment centers mandatory for all Swiss national males aged 18-25 years. A total of 3,700 sexually active young males filled out a questionnaire at baseline (T0) and follow-up (T1: 15.5 months later). Main outcome measures were self-reported premature ejaculation (PE) and erectile dysfunction (ED).


Overall, 43.9% of young males who reported (PE) and 51% of those reporting (ED) at T0 still reported it at T1. Moreover, 9.7% developed a PE problem and 14.4% developed an ED problem between T0 and T1. Poor mental health, depression, and consumption of medication without prescription were predictive factors for PE and ED. Poor physical health, alcohol consumption, and less sexual experience were predictive factors for PE. ED persistence was associated with having multiple sexual partners.


This is the first longitudinal study to examine sexual dysfunctions among young males. Our results show high prevalence rates among young males for maintaining or developing a sexual dysfunction over time. Consequently, when consulting with young males, health professionals should inquire about sexual dysfunctions as part of their routine psychosocial assessment and leave the subject open for discussion. Future research should examine in more detail the relationship between sexual dysfunctions and poor mental health.
