Vaginal dryness and discomfort
Vaginal dryness, soreness and pain during sex are very common during and after chemotherapy, especially when periods stop or menopause arrives early. They are rarely mentioned by anyone, yet they are easy to help with lubricants, moisturisers and gentle approaches. If dryness continues after treatment, further options exist, and your team can advise safely.

The short answer
Why does chemotherapy cause vaginal dryness, and what helps?
Vaginal dryness is one of the most common effects of cancer treatment in women, and one of the least discussed. Chemotherapy can reduce the ovaries' production of oestrogen, and in many women periods become irregular or stop. Oestrogen keeps the lining of the vagina thick, moist and stretchy. When it falls, the lining becomes thinner and drier, which can cause itching, burning, soreness, light bleeding after sex, pain during intercourse and more frequent urine or vaginal infections. Hormone-blocking treatments for breast and some other cancers, surgery to remove the ovaries, and pelvic radiotherapy can make these changes stronger or longer lasting.
The good news is that dryness is usually easy to improve. Water-based or silicone-based lubricants make sex more comfortable. Vaginal moisturisers, used regularly and not just before sex, help the tissues hold moisture day to day. Gentle hygiene, avoiding perfumed products and taking sex slowly also help. For some women, a low-dose vaginal hormone treatment may be considered, but whether this is safe depends on the type of cancer, so it must be discussed with your oncologist. Dryness often improves if periods return after treatment; if menopause is permanent, ongoing care keeps symptoms under control.
It is not a sign of low desire
Dryness is a physical change in the tissues. Desire and arousal can be present even when the body does not produce enough moisture.
Infections can mimic dryness
Thrush and urine infections are more common during treatment and can cause similar itching and burning.
Pain should not be endured
Painful sex can make the body tense up, which worsens pain. Stop, and ask for help.
Tell your team or a gynaecologist about dryness, itching or pain. It is a recognised side effect and there are safe options.What helps
Options for easing dryness and discomfort
- Lubricants
- Used during sex to reduce friction and pain. Water-based lubricants are easy to wash off and safe with condoms; silicone-based ones last longer. Avoid oil-based products with condoms.
- Vaginal moisturisers
- Used regularly, often a few times a week, to help the vaginal lining hold moisture and feel more comfortable in daily life, not just during sex.
- Gentle hygiene
- Wash with plain water, avoid soaps, douches, perfumed washes and sprays, and wear loose cotton underwear.
- Vaginal hormone treatment
- Low-dose treatment applied inside the vagina can help some women, but it is not suitable for everyone, especially after hormone-sensitive cancers. Your oncologist must advise.
- Pelvic floor relaxation
- Learning to relax the pelvic floor muscles reduces pain. A women's health physiotherapist can help.
- Vaginal dilators
- After pelvic radiotherapy or surgery, dilators may be advised to keep the vagina supple. Your team will guide you.
Not sure whether this applies to you?
Ask an oncologistPractical
Making sex more comfortable
Small changes that often make a big difference.
Use plenty of lubricant
Apply generously to both partners, and reapply as needed. More is usually better than too little.
Choose products that are
- Free from perfume and colour
- Water or silicone based
Take more time
Longer foreplay increases natural arousal and moisture, and helps muscles relax.
Try positions that give you control
Positions where you control depth and pace can reduce pain and increase confidence.
Also helpful
- Pillows for support
- Stopping if anything hurts
Pass urine afterwards
Emptying the bladder after sex reduces urine infections, which are more common during treatment.
Closeness without penetration
On sore days, touch, massage and other intimacy can be just as meaningful.

Contact your team the same day for any of these
Vaginal bleeding that is heavy or does not stop, especially with low platelets · fever or shivering · a bad-smelling or unusual discharge · sores, blisters or ulcers in the genital area · severe pain or swelling · burning when passing urine with fever or back pain · bleeding after menopause that is new and unexplained. Call your chemotherapy helpline or go to the nearest emergency department for heavy bleeding, and say clearly that the person is on chemotherapy.
Being straight with you
What this page cannot tell you
It cannot tell you whether vaginal hormone treatment is safe for you. That depends on your cancer type, whether it is hormone-sensitive, and your other treatments. Only your oncologist, ideally with a gynaecologist, can advise.
It also cannot tell you whether your dryness will be permanent. That depends on your age, whether your periods return, and whether you continue hormone-blocking treatment.
Thrush during treatment
Antibiotics and steroids increase thrush risk. Itching with thick white discharge should be checked and treated.
Avoid home remedies inside the vagina
Coconut oil, ghee, curd or herbal preparations can irritate or introduce infection. Ask before using anything.
Dryness can affect daily comfort
Some women feel discomfort when sitting, walking or cycling, not only during sex. Regular moisturisers help.
Pelvic radiotherapy has extra effects
It can cause narrowing and scarring. Follow advice on dilators and gentle activity.
Single women are affected too
Dryness and discomfort can occur without sex and are equally worth treating.
Talking to your partner helps
Explaining that dryness is physical helps partners understand and adapt.
A women's health physiotherapist
They can help with pelvic floor tension and pain, which often develop after painful sex.
Ask for a female doctor if you prefer
It is reasonable to ask to discuss this with a female doctor or nurse.
Buying products discreetly
Lubricants and moisturisers are available from pharmacies and online. Ask your team which types to look for.
Moisturisers work best with regular use
Vaginal moisturisers are different from lubricants. They are designed to be used on a regular schedule, whether or not you are having sex, so the tissues stay more comfortable over time. It can take a few weeks of steady use to notice the full benefit, so give them time before deciding they do not help.
Urine symptoms can be linked
Lower oestrogen also affects the bladder opening, which can cause urgency, stinging and more frequent infections. Mention urine symptoms alongside dryness, as they may improve together.
Dryness and hormone-blocking tablets
Women taking hormone-blocking tablets after chemotherapy often notice dryness becoming more marked over time. This is expected and not a reason to stop the tablets. Tell your team, as there are ways to manage it that fit with your cancer treatment.
Regular gentle activity helps
Sexual activity or gentle use of dilators, when comfortable, can help the vaginal tissues stay more elastic. Go slowly and stop if there is pain.
What to do next
Use lubricants during sex and moisturisers regularly, keep hygiene gentle, take things slowly, avoid home remedies inside the vagina, report infections or bleeding, and ask your oncologist whether other treatments are safe for your type of cancer.

Commonly believed
Four beliefs about vaginal dryness
"Dryness means I do not want my partner."
It is a physical change from lower hormones, not a sign of lost affection or desire.
"I just have to put up with painful sex."
Lubricants, moisturisers and other options usually make sex comfortable again.
"Any oil will work as a lubricant."
Oils can damage condoms and cause irritation or infection. Use water or silicone-based products.
"Hormone creams are safe for everyone after cancer."
They are not suitable after some cancers. Always ask your oncologist first.
Questions we are asked
Common questions about vaginal dryness
Why does chemotherapy cause vaginal dryness?
It can lower oestrogen from the ovaries, making the vaginal lining thinner and drier. Hormone-blocking treatments and pelvic radiotherapy add to this.
What helps vaginal dryness?
Lubricants during sex, regular vaginal moisturisers, gentle hygiene, more time for arousal, and sometimes other treatments your oncologist approves.
Is vaginal dryness permanent?
It often improves if periods return. With permanent menopause or ongoing hormone treatment, it may continue but can be managed.
Which lubricant should I use?
Water-based or silicone-based, without perfume or colour. Avoid oils with condoms.
Can I use vaginal hormone cream?
Only if your oncologist agrees. It may not be suitable after hormone-sensitive cancers.
Why do I keep getting infections?
Thinner tissues, low counts, antibiotics and steroids increase infection risk. Report symptoms so they can be treated.
Is bleeding after sex normal?
Light spotting can happen with dryness, but heavy or persistent bleeding, especially with low platelets, needs prompt review.
Who can help?
Your oncologist, a gynaecologist, a women's health physiotherapist or a sexual health specialist.
