Introduction.Endocrine disorders of sex steroid hormones may adversely affect men’s sexual
function.
Aim.T o provide expert opinions/recommendations concerning state-of-the-art knowledge for the
pathophysiology, diagnosis and treatment of endocrinologic sexual medicine disorders.
Methods.An International Consultation in collaboration with the major urology and sexual med-
icine associations assembled over 200 multidisciplinary experts from 60 countries into 17 commit-
tees. Committee members established specific objectives and scopes for various male and female
sexual medicine topics. The recommendations concerning state-of-the-art knowledge in the respec-
tive sexual medicine topic represent the opinion of experts from five continents developed in a sci-
entific and debate process. Concerning the Endocrine committee, there were eight experts from
seven countries.
Main Outcome Measure.Expert opinions/recommendations are based on grading of evidence-
based medical literature, extensive internal committee discussion over 2 years, public presentation
and deliberation.
Results.Hypogonadism is a clinical and biochemical syndrome characterized by a deficiency in
serum androgen levels which may decrease sexual interest, quality of erections and quality of life.
Biochemical investigations include testosterone and either bioavailable or calculated free testos-
terone; prolactin should be considered when hypogonadism has been documented. If clinically indi-
cated, androgen therapy should maintain testosterone within the physiological range avoiding
supraphysiologic values. Digital rectal examination and determination of serum prostate specific
antigen values are mandatory prior to therapy and regularly thereafter. Androgen therapy is usually
long-term requiring regular follow-up, frequent monitoring of blood levels and beneficial and
adverse therapeutic responses.
Conclusions.Safe and effective treatments for endocrinologic sexual medicine disorders examined
by prospective, placebo-controlled, multi-institutional clinical trials are needed.
