Changes in sexual functions are very common among women with advanced
multiple sclerosis but occur also in early and mild cases. Decreased s
exual desire as well as decreased or absent lubrication are almost as
common as diminished orgasmic capacity, changes in orgasmic quality or
anorgasmia. Changes in sexual functions correlate both to neurologica
l symptoms from the sacral segments, such as sensory dysfunction in th
e genital area or weakness of the pelvic muscles, and to bladder and b
owel dysfunction. However, disability in itself and a number of psycho
logical and social factors may explain the problems but also gives clu
es to the treatment.
