Multiple Sclerosis

Multiple Sclerosis effects the central nervous system, which controls cognitive, motor and sensory functioning. It is highly linked to orgasmic disorders, as well as loss of muscle tone and fatigue which can make sexual intercourse difficult.


Parkinson’s Disease

There are a number of factors involved in impaired sexual function in Parkinson’s. These include decreased dopamine activity, decreased mobility and dysfunction of the autonomic nervous system (ANS). The ANS controls bodily functions that are not under conscious control. This can affect various stages of the sexual response cycle (i.e. arousal, lubrication, orgasm). Moreover patients suffering from an illness such as Parkinson’s may also suffer from depression and anxiety, which further impact sexual function adversely.

Couples where one partner has motor difficulties need not stop enjoying sex. Some couples find it difficult adjusting to the new roles they both have to undertake (“patient” and “carer”), yet with time and communication, people find that this can make them closer. It is important the couple still spend time together doing things they both enjoy. Affection and intimacy are the foundation for continuing to enjoy sex, although they may have to make some adjustments. For example, they may have to consider alternate sexual positions or activities, such as mutual masturbation or oral sex.
