Sex and MS: relationship with depression, fatigue and disability


1 September 2017

The study in brief

People with MS from across the UK taking part in the TONiC study completed a pack of questionnaires on sexual functioning, fatigue, anxiety and depression and day-to-day life. 431 people answered questions on sexual functioning.

Of those who were sexually active, only 12.5% reported no impact on any aspect of sexual function.

These results show that the effect of MS on sexual functioning is significant. The psychological aspects of MS affecting sexuality - such as feeling less attractive or concerns about sexually satisfying a partner - were found to have a considerable impact, contributing significantly to the other areas of sexual problems. Depression, rather than affecting sexual functioning, was found to be affected by the psychological aspects, with worries about sexual functioning increasing depressive symptoms.

The psychological aspect of sexual problems, an area which is frequently neglected during discussions with health professionals, is clearly important to take into account. The researchers highlight the need to address people's worries about sexuality, offering the potential to reduce depression.

The study in more detail

Background

Sexual activity is an important part of life for many people and contributes to their quality of life, the quality of their relationships and to self-esteem and self-image. Sexual problems in both men and women are common in MS but is not clear how these affect, or are affected by, other symptoms of MS, such as depression, fatigue and level of disability. This research investigated the connections between these different aspects of MS and how they are influenced by age, gender and type of MS.

How this study was carried out

People with MS from across the UK taking part in the TONiC study completed a pack of questionnaires on sexual functioning, fatigue, anxiety and depression and day-to-day life. At the time of the analysis, a total of 722 participants had returned questionnaires. Of these, 538 were sexually active and 431 (80%) answered questions on sexual functioning.

What was found

Of those who were sexually active, only 12.5% reported no impact on any aspect of sexual function.

Sexual problems were classified into three categories:

  • Primary - MS directly affects sexual response, such as problems with orgasm, numbness in genital area, erections or vaginal lubrication
  • Secondary - MS symptoms indirectly affect the sexual response, such as bladder or bowel, pain or spasticity problems which make sexual activity more difficult
  • Tertiary - psychological and social aspects of MS that affect sexuality, such as being afraid of being rejected because of MS, feeling less attractive or concerns about sexually satisfying a partner. These aspects were grouped together as "worries" by the researchers.

Only 16.5% reported no primary aspects, meaning the great majority (83.5%) experience some MS-related symptoms that directly affect their sexual functioning. In addition, only 22.5% reported no secondary aspects and another 22.5% reported no tertiary aspects. Almost two-thirds (63.8%) indicated that they were affected by all three areas.

Unsurprisingly, there was a strong connection between level of disability and all three categories of sexual problems. There were some differences in the sexual problems experienced by people with different types of MS; people with secondary progressive MS had more primary sexual problems, those with relapsing remitting MS had least problems across all three categories. Men had significantly more "worries" than women, although the type of worries varied by gender with women being more likely to worry about feeling less attractive due to their MS and men being more likely to worry about sexually satisfying their partner.

Depression, rather than directly affecting sexual functioning, was found to be affected by the tertiary aspects, with worries about sexual functioning increasing depressive symptoms.

What does it mean?

These results show that the effect of MS on sexual functioning is significant. The tertiary aspects (“worries”) were found to have a considerable impact, largely contributing to the other areas of sexual problems.

The psychological aspect of sexual problems, an area which is frequently neglected during discussions with health professionals, is clearly important to take into account. The researchers highlight the need to address people's worries about sexuality, offering the potential to reduce depression.

Abstract

More about MS and sex

Both men and women with MS may have sexual issues but many people are reluctant to discuss them due to embarrassment and shyness.

Sometimes problems are minor and can be managed easily with general advice, at other times they can be more significant and require specialist input.

Sexual difficulties can be experienced at any time during the course of MS. They may be the result of other MS symptoms including bladder symptoms, pain, fatigue or spasticity. They can also be a side effect of medication so it can be worth having this reviewed.

Living with MS can have a significant effect on someone's self-esteem and self-image and this can affect their sexuality.

However, not every sexual problem is due to MS and many of the difficulties described by people with MS also occur in the general population, for example, anxiety or other medical conditions.

The MS Trust has two resources for people with MS and their partners. They can be read online, downloaded or ordered free of charge.

Sexuality and MS: a guide for women explains how MS can impact on both sexuality and intimacy and offers positive and practical solutions. It is illustrated with comments, opinions, experiences and tips from women with MS.

Sex and MS: a guide for men looks at how MS can affect the sex lives of men and how these issues can be managed.

More about TONiC

The Trajectories of Outcome in Neurological Conditions (TONiC) study is one of the largest ever quality of life studies for people with neurological conditions in the UK. It will identify factors that affect quality of life in MS and investigate how these factors interact. The results from TONiC will be used to tailor services, to focus therapies and to identify aspects of MS that are important to people, but might be underestimated by current service provision.

TONiC is still recruiting new participants. Anyone with MS, regardless of type or stage of MS, is welcome to take part in the study. You will be asked to complete a set of questionnaires initially and then repeat this again later to give an idea of how things have changed for you. You can find out more by contacting one of the recruiting centres or by contacting the TONiC team directly.
