Mood changes and sex hormones

Read about how lower testosterone levels might cause mood changes - and tips to cope.

In men there is conflicting evidence about whether low testosterone levels have an impact on mood changes or not.

Some trials show that men having hormone treatment are more likely to feel sad or depressed, but other trials don’t.

Hormones and mood changes

Some cancer treatments lower the levels of sex hormones in the body. These include oestrogen and progesterone in women and testosterone in men. Low levels of sex hormones can sometimes cause mood changes.

The causes of mood changes can be difficult to assess because many factors affect mood, especially when you have cancer. Cancer can make you feel anxious, sad, stressed or irritable at times.

Hormone related mood changes can include:

  • feeling anxious, panicky and irritable
  • feeling very sad, which for some people can develop into depression
  • mood swings - one minute feeling fine and the next feeling low, panicky, and very irritable or tearful

Hormone replacement therapy (HRT)

You might be able to have hormone replacement therapy (HRT) to help control symptoms caused by low hormone levels.

But some treatments for breast or prostate cancer aim to stop the body producing sex hormones or to block the action of the hormones. If you are having that kind of treatment, unfortunately you can’t take HRT to help control your symptoms.

Coping with mood changes

Talk to your doctor or nurse if you feel sad or anxious and are finding it difficult to cope.

Sadness and depression can be treated in different ways, including counselling and anti depressants.

There are also ways you can help yourself, such as:

  • eat well
  • do relaxation or deep breathing exercises
  • take regular exercise that you enjoy, such as walking, swimming or yoga
  • avoid alcohol
  • get enough sleep – this can be difficult if you are feeling anxious or sad, but lack of sleep can make it harder to cope
  • get help to control other symptoms – if you don’t feel well it can make coping with mood changes more difficult
  • talk to other people about how you feel
