Disorders of ejaculation.

Following John Hunter's example set over 200 years ago, it is clear that there is much to study and understand in disorders of ejaculation. Congenital malformations and their relationship to genetic disorders are now more clearly understood: these are matters of the utmost importance in the present era of assisted reproduction, if perpetuation of serious anomalies, such as fibrocystic disease, is to be avoided. Surgically induced injuries that impact upon male reproductive function are now recognized and largely preventable by careful attention to preservation of normal structures during extirpative surgery. Much work remains to be done on functional disorders, especially on the side effects of drug therapy, where some insight may be gained into the function and disorders of the basal ganglia--the 'dark basements of the mind'.
