Introduction. Sexual dysfunction in men, such as erectile dysfunction, hypogonadism, and premature ejaculation,
generates considerable attention. Its association with physical and psychological health is an issue which should be
addressed seriously.
Aim. A review of the literature pertaining to the correlation between sexual dysfunction and physical and psycho-
logical health.
Methods. PubMed search for relevant publications on the association between sexual dysfunction in men and
physical and psychological health.
Main Outcome Measure. Clinical and epidemiological evidence that demonstrates the association between sexual
dysfunction in men and physical and psychological health.
Results. Sexual dysfunction, i.e., erectile dysfunction, hypogonadism, and premature ejaculation, has been shown to
be associated with physical and psychological health. There is a strong correlation between sexual dysfunction and
cardiovascular disease, metabolic syndrome, quality of life, and depression.
Conclusion. The association between men’s sexual dysfunction and physical and psychological health is real and
proven. Therefore, it should not be taken lightly but instead treated as a life-threatening medical problem. Tan HM,
