Sex and fertility

Read about how non Hodgkin lymphoma and its treatment might affect your sex life and your ability to have children. 

How treatment can affect you

Non Hodgkin lymphoma and its treatment do not always affect your sex life. But you will probably go through times when you don't feel like sex because you are too tired or have side effects.

Precautions

You need to take precautions against pregnancy if you are having chemotherapy.

Men having chemotherapy always need to wear a condom during sex. Some women have said that when their partner was having chemotherapy the semen caused a stinging sensation in their vagina. This means some of the drug may be coming through. Doctors don't know enough about whether this could be harmful.

For women having chemotherapy, the drugs could damage the developing baby if you become pregnant. Even if your periods have stopped, it might be possible to get pregnant. So you should still take precautions.

Sexual intercourse might not be recommended if you have a very low platelet count, as there may be a risk of bleeding. Discuss this with your doctor or nurse if you are not sure.

Early menopause

Sometimes chemotherapy can give women an early menopause.  If your periods stop permanently after chemotherapy, you have had an early menopause. This can cause other symptoms apart from not having periods. You might have:

  • hot flushes and sweats
  • dryness of the vagina
  • less interest in sex
  • dry skin
  • loss of energy
  • mood swings, loss of concentration or just feeling low

Your doctor will probably offer you hormone replacement therapy (HRT) if you have an early menopause. HRT is treatment with the female sex hormones you would produce naturally if you had not had an early menopause. The hormones are called oestrogen and progesterone. 

HRT can stop all the symptoms of early menopause. It can also help to prevent long term problems like bone thinning (osteoporosis).

You can have HRT by taking tablets or by using skin patches that are like sticking plasters. The dose of hormones is lower than the dose you would normally produce if you had not had an early menopause. So you are very unlikely to have any side effects.

How chemotherapy can affect fertility

Some chemotherapy treatments for non Hodgkin lymphoma can cause infertility. But this does not happen with all chemotherapy treatment used for NHL. If they can, doctors will use drugs that don't cause infertility instead of those that do. But the first priority is treating your non Hodgkin lymphoma effectively.

If you become infertile you will not be able to have children after your treatment. Having a stem cell or bone marrow transplant will almost certainly mean you will be infertile.

With some chemotherapy treatment, it is not possible for your doctor to be certain whether you will be infertile or not. This will depend on

  • The drugs you are given
  • The total dose of each drug
  • Your age if you are a woman

Some drugs are likely to cause infertility but do not always do so. Some people may be made infertile at a lower dose of a particular drug than other people. Some drugs cause temporary infertility. So your fertility may come back from six months to a year after your treatment has finished.

Your doctor or specialist nurse will tell you whether your chemotherapy is likely to make you infertile and can answer your questions before you start your treatment. If you have a partner, you may want to see the doctor together. You can then both ask questions and discuss any fears or worries.

Infertility in men

Even if your treatment will stop you producing sperm, it may be possible for you to have sperm frozen and stored before you start your treatment. This is called sperm banking. Sperm banking means you will be able to have children in the future because the frozen sperm can be used to make your partner pregnant.

Teenage boys can also have sperm frozen. Their sperm can be stored for use in later years.

Sometimes men who have lymphoma have fewer sperm in their semen. It is not then possible to store the sperm. But there are newer techniques to help men with low sperm counts.  It is important that you discuss sperm banking with your doctor before your treatment starts.

Infertility in women

The closer you are to having your menopause, the more likely it is that chemotherapy will make you infertile. But if your periods do stop or become irregular during your chemotherapy, this does not necessarily mean you will be infertile. Your periods might go back to normal six months to a year after treatment has finished.

The only ways for women to preserve fertility are to have embryos or eggs frozen. This is more complicated than sperm banking is for men. You have to take hormones to stimulate your ovaries to make many more eggs than usual. This takes a couple of weeks at least, depending on where you are in your menstrual cycle.

You can have the eggs fertilised and stored as embryos if you have a partner. But it is now also possible to have just your eggs frozen.

Talk to your lymphoma specialist as early as possible if you think you would like to do this. You have to do it before you start this treatment. It takes a few weeks, so it could delay your chemotherapy.

With some types of faster growing lymphoma, this might not be possible. Your doctor might feel you need to start treatment straight away.

Coping

It can be extremely upsetting to find out that your cancer treatment means you will not be able to have children. It can seem very unfair to have to cope with this as well as your cancer. Even if you haven't really thought about having children before, losing your fertility can be very difficult to come to terms with. It can affect the way you feel about yourself.

It takes time to come to terms with this. Give yourself time to adjust and feel sad. Talking to someone close will almost certainly help. But you might not be able to do this for a while.

You may want to talk to someone other than your partner, family or friends. Some people find it helpful to talk to a therapist or counsellor. Ask your doctor or nurse if you can be put in touch with some professional help if you think it would be helpful for you.

For information, you can call the Cancer Research UK nurses free on 0808 800 4040, from 9am to 5pm, Monday to Friday. They are happy to help. They can give advice about who can help you and what kind of support is available.
