Women’s Health Clinic FAQ
How does the ratio of parabasal to superficial cells on a maturation index shift during vaginal atrophy?
Vaginal atrophy is not only a dryness problem; it changes epithelial maturation, glycogen, pH and the protective microbiome in ways patients can sometimes feel as burning, irritation or recurrent symptoms.
Direct answer
As oestrogen exposure falls, vaginal epithelial maturation slows. Superficial cells decrease and parabasal cells become more prominent on the maturation index, reflecting thinner, less mature epithelium. The benchmark should explain that VMI supports assessment but is not routinely required for every clinical diagnosis.
The safest answer separates genitourinary syndrome of menopause from infection, inflammatory skin disease, ulcers, bleeding, urinary red flags and other causes before choosing treatment.

Atrophy assessment
At a glance
These points help place the finding in clinical context.
At a glance
Clinical summary
Cells
Superficial cells fall and parabasal cells rise.
Glycogen
Less mature epithelium provides less substrate.
Microbiome
Lactobacilli may decline as pH rises.
Context
Symptoms and infection checks still matter.
Important safety note
Seek medical advice promptly for postmenopausal bleeding, bleeding after sex, ulcers, unusual discharge, fever, severe pelvic or vulval pain, urinary retention, blood in urine, recurrent infection symptoms or a lesion that does not heal.
Oestrogen
Tissue signs

Review
Detailed answer
Detailed answer
Oestrogen supports maturation of the vaginal epithelium, so low oestrogen tends to reduce superficial cells and increase parabasal cells.
Clinical context
Superficial epithelial cells normally contain glycogen, which helps Lactobacillus species produce lactic acid.
pH
Vascularity
Safety
What changes
Oestrogen supports maturation of the vaginal epithelium, so low oestrogen tends to reduce superficial cells and increase parabasal cells.
Why it happens
Superficial epithelial cells normally contain glycogen, which helps Lactobacillus species produce lactic acid.
What it does not prove
When glycogen and lactobacilli decline, vaginal pH can rise and the tissue may become more vulnerable to irritation or infection-like symptoms.
What keeps it safe
These findings support understanding, but they do not prove that every symptom is caused by atrophy.
What this means in practice
A responsible page explains the tissue mechanism without making one sign or test sound diagnostic on its own.
Symptoms such as bleeding, ulcers, severe pain, discharge or urinary red flags should be routed to medical review.
Patient safety
Why this matters
Atrophy can be uncomfortable and intimate, but the clinical priority is to explain the sign clearly without missing other causes.
It explains symptoms
Epithelial thinning, lower moisture, pH change and tissue fragility can make contact, sex or examination uncomfortable.
It avoids over-testing
Objective measures may support assessment, but they are not required for every patient.
It protects safety
Bleeding, ulcers, infection symptoms and atypical lesions need review rather than simple reassurance.
It supports treatment choice
Local tissue treatment, moisturisers, lubricants or referral depend on symptoms, risk factors and preferences.
A whole-context assessment
The useful question is not just whether tissue looks atrophic, but whether the finding explains the patient's symptoms safely.
That is why examination, symptom pattern, menopause history, medication, infection risk and red flags all matter.
Considerations
What to consider
Before deciding what the finding means, consider symptoms, menopause or treatment history, pH or cytology if used, urinary symptoms, bleeding, discharge, pain, skin changes and response to previous treatment.
Consultation priorities
Assessment reviews dryness, burning, discharge, odour, urinary symptoms, sexual discomfort and menopause or treatment history.
Examination
Tests
Review
History
Assessment reviews dryness, burning, discharge, odour, urinary symptoms, sexual discomfort and menopause or treatment history.
Examination or tests
A clinician may use pH, microscopy, swabs or cytology if the presentation is unclear or recurrent.
Treatment choice
Treatment aims to improve tissue comfort and reduce triggers while excluding infection or dermatoses.
Follow-up
If symptoms persist, review should reconsider the diagnosis rather than simply repeating the same approach.
Practical expectations
Response varies; symptom relief, tissue comfort, examination findings and red flags should be reviewed over time.
Costs, prescription options and treatment suitability should be confirmed directly with the clinic or prescribing clinician before booking.
Common concerns and myths
Common misconceptions
These myths can make vaginal atrophy sound either too simple or unnecessarily frightening.
Myth: lactobacilli decline has one cause
Reality: oestrogen, glycogen, pH, infection and recent treatments can all influence the microbiome.
Myth: raised pH always means atrophy
Reality: bacterial vaginosis, semen, blood and infection can also affect pH.
Myth: cell ratios predict symptoms perfectly
Reality: test findings and symptom severity do not always match.
Evidence and context
The finding only becomes clinically meaningful when it fits the symptoms, examination and differential diagnosis.
Treatment routes
Options may include non-hormonal moisturisers or lubricants, local vaginal oestrogen, review of medicines, infection testing or specialist referral.
Safety checklist
Safety checklist
Use these checks before assuming a tissue sign is simply atrophy.
Is the symptom pattern clear?
Dryness, burning, entry pain, urinary symptoms, discharge and bleeding should be separated.
Has infection or skin disease been considered?
Viral lesions, thrush, bacterial vaginosis, dermatitis, lichen conditions and trauma can overlap with atrophy signs.
Are red flags absent?
Seek medical advice promptly for postmenopausal bleeding, bleeding after sex, ulcers, unusual discharge, fever, severe pelvic or vulval pain, urinary retention, blood in urine, recurrent infection symptoms or a lesion that does not heal.
Is review planned?
A plan should explain what improvement would look like and when persistent signs need reassessment.
Reassuring signs
Proceeding is more reasonable when symptoms, examination and safety checks all fit a clear GSM pattern.
No red flags
Review plan
Reasons to pause
Seek medical advice promptly for postmenopausal bleeding, bleeding after sex, ulcers, unusual discharge, fever, severe pelvic or vulval pain, urinary retention, blood in urine, recurrent infection symptoms or a lesion that does not heal.
Ulcers
Infection
When to escalate
When to seek medical help
Some vaginal, vulval or urinary symptoms should be assessed promptly.
Use NHS 111 online
Bleeding
Postmenopausal bleeding, bleeding after sex or unexplained bleeding should be assessed by a clinician.
Ulcers or unusual lesions
Ulcers, blisters, a persistent sore area or a lesion that does not heal should not be assumed to be atrophy.
Infection or urinary symptoms
Fever, unusual discharge, blood in urine, urinary retention or recurrent infection symptoms need medical advice.
Emergency symptoms
Call 999 in a life-threatening emergency, including collapse, chest pain, breathing difficulty or sudden neurological symptoms.

More clinical detail
Why cell findings and symptoms may differ
VMI, pH and microbiome findings describe the tissue environment, but symptom severity also depends on pain sensitivity, infection, friction, sexual activity, urinary symptoms and other vulval conditions.What to ask in consultation
Ask whether the pattern fits GSM, whether infection or dermatoses should be excluded, and whether treatment response will be judged by symptoms, examination or selected tests.Regulatory resources

Next step
Book a menopause or vaginal health consultation
A consultation can clarify whether symptoms fit vaginal atrophy, whether another cause needs excluding, and which treatment options are suitable.
