Can PLS affect sexual function?

The short answer appears to be “yes”, although it is important to remember that sexual desire and/or function can be affected by many other factors such as older age, stress, depression, fatigue, medical disorders or medications.

Some people report that stiffness, spasms and cramps that are part of PLS may either inhibit (or intensify) orgasm, or that orgasm may bring on leg stiffness, spasms or clonus. Stiffness of the legs or arms may cause difficulty using certain positions for intercourse.
