Sexual side-effects for men
It is natural for you to be concerned about your sex life. Some men with cancer feel that changes to their sex lives and their relationships are some of the biggest issues they face.
What are the possible sexual side-effects?
- Erectile dysfunction (ED). Finding it hard to get or keep an erection strong enough for sex. This can be caused by damage to nerves or blood vessels after surgery or radiotherapy. There are treatments to help with erectile dysfunction, so let your doctor know if it’s a problem for you.
- ‘Dry’ orgasm. After some treatments, like pelvic radiotherapy or prostate surgery, some men find that an orgasm has less semen than usual or they have a ‘dry’ orgasm, where no semen is ejaculated. Dry orgasm means you won’t be able to father a child, as there is no semen.
- Orgasm changes. Many men describe the sensation of orgasm as different to their orgasm before surgery. A few men describe it as lasting longer, others describe some pain after orgasm in the early days, or some simply describe it as different.
- Changes to your genitals. Up to a year after prostate surgery you may notice your penis has shortened. Hormone therapy may make your testicles smaller.
What can help?
Treatments that encourage blood flow into your penis, such as tablets or a vacuum pump, may help to prevent a shortened penis.
Loss of sex drive (libido)
Losing interest in sex can be caused by physical or emotional changes. For example, if your hormone levels are affected by treatment or you are very fatigued you may find you have less sex drive.
Emotions like anxiety, depression or sadness can make you less interested in sex too. You may also feel less confident about your physical appearance, if it has changed after treatment.
What can help?
If low libido is caused by low testosterone, your doctor may prescribe testosterone for you. Or you may be too sore to have sex after surgery.
Trying to find out the cause of fatigue and treating it can help. For example, you may need a blood transfusion if your fatigue is due to a low red blood cell count or dietary advice can help if you’re not eating well. Read more about fatigue and tips to help.
If you are struggling with difficult emotions, talking about your feelings to a partner, trusted friend or a professional may help. We have advice on talking to your partner and ways to get support on our page Sexual side-effects cancer treatment. Or get support or information on free counselling and other services to help you from one of our cancer nurses.
Pain and discomfort
It may be difficult to hold or hug your partner, especially if your wounds are still healing or if you have scarring after surgery. And areas treated with radiotherapy may be tender and painful to touch if it has been treated with radiotherapy.
What can help?
- Taking painkillers before sex
- Changing position during lovemaking so there is less direct pressure on the affected area.
If you have a stoma: Having a stoma can affect how you feel about your body. You may also be afraid that the bag will become dislodged or cause damage to the stoma. Empty the bag before sexual intimacy and roll it up or tape it down so it will not get in the way, if you wish. If you need more advice talk to your doctor, specialist nurse or stoma nurse, they are all experienced in dealing with these issues. Read more about stomas and sex.
Treatment for erectile dysfunction (ED)
Getting the best from treatment
Don’t expect too much the first few times you try a treatment. It can take time to get used to everything, so don’t put too much pressure on yourself. Don’t give up. You might need to try a few different things or use 2 treatments together to find what works for you. Go back to the doctor if you feel a treatment isn’t helping.
Getting early treatment for ED
Taking medication or using a vacuum pump for erectile dysfunction soon after prostate surgery can improve your chance of having erections again. Even if you’re not interested in sex, taking the tablets or using a vacuum pump at an early stage may improve your chances of having erections if you want to have sex again in the future. Do discuss this with your surgeon, nurse or your GP.
Treatments to help with erection problems (erectile dysfunction)
- Tablets. These help you to get an erection. They only work if you are interested in having sex and you need to get sexually aroused for them to work. It’s quite common for tablets not to work on their own. Many men have more success with another treatment or combination of treatments.
- Vacuum pump. A tube is placed over your penis and a pump creates a vacuum, which causes an erection. A rubber ring is placed at the base of your penis to keep it hard while you have sex. The tube is removed.
Some men prefer the pump because it avoids the use of drugs. Another advantage is that the cost of the pump is a once-off payment. It can take some practice to get the technique right. You can use the pump as often as you like.
It can also be used together with tablets or injections. You may be advised to use to pump to encourage blood flow to your penis after surgery or radiation treatments, even if you are not ready to have sex.
- Urethral pellets. These contain drugs to help you get an erection. They are put into the opening or ‘eye’ of your penis. Then the pellet is massaged into the penis to help it melt. Standing or walking around can help your erection develop better. You should get an erection in 5 to 15 minutes.
Some men get some pain, redness or a burning sensation in the penis or testicles after using the pellets.
- Penile injections. You inject a drug into the base of your penis. You should get an erection within about 15 minutes. The erection lasts from 30 minutes to 2 hours. The first dose is given by your doctor in the hospital so that they can see how well you respond and decide the best dose for you. Then you or your partner will be taught how to give the injection at home.
The injection does not hurt, as the needle is very fine. You should not inject more than 2 or 3 times a week.
- Penile implants (surgery). This is where tubes, a reservoir (container) and a pump are put inside your body during an operation. The implant means you can press on the pump to make your penis fill with fluid and get hard.
Most men and their partners are very satisfied with these devices. Possible side-effects include infection and pain.
