Pelvic Floor Dysfunction and Vaginismus: What Is Happening — and How to Find Relief
Pelvic floor dysfunction affects at least one in three women. Vaginismus — involuntary tightening of the vaginal muscles — affects an estimated 5–17%, though the true figure is likely higher because many cases go unreported. These conditions significantly affect quality of life, relationships, and reproductive health — and they are consistently undertreated because they are consistently under-discussed.
This is a practical guide to what is happening, why, and what helps.
What the Pelvic Floor Is
The pelvic floor is a group of muscles, ligaments, and connective tissue forming a hammock-like structure at the base of the pelvis. It supports the bladder, uterus, and bowel — and plays a critical role in urination, bowel control, sexual function, menstrual health, and core stability.
Like any muscle group, the pelvic floor can be too tight (hypertonic), too weak (hypotonic), or uncoordinated — failing to contract and release appropriately. Problems arise from all three patterns.
Pelvic Floor Dysfunction: The Hypertonic Pattern
The most commonly missed pattern is an overactive pelvic floor — muscles that are chronically too tight. This is less intuitive than weakness but is extremely common, particularly in women who carry significant stress in the body, have experienced trauma, or have a history of painful periods.
Signs of hypertonic (too tight) pelvic floor:
- Pain during intercourse (dyspareunia)
- Difficulty with tampon insertion
- Constipation or difficulty with bowel movements
- Urinary urgency or incomplete emptying
- Lower back or hip pain
- Pelvic heaviness or pressure
- Pain that worsens with sitting
Doing Kegel exercises (strengthening) for a hypertonic pelvic floor worsens the problem. The solution is release — not contraction.
Pelvic Floor Dysfunction: The Hypotonic Pattern
A weak pelvic floor is the more familiar pattern — typically associated with childbirth, ageing, and oestrogen decline.
Signs of hypotonic (too weak) pelvic floor:
- Urinary leakage — with coughing, sneezing, jumping (stress incontinence)
- Urgency — difficulty holding urine
- Pelvic organ prolapse — a feeling of heaviness or bulging in the vagina
- Reduced sensation during sex
Vaginismus
Vaginismus is the involuntary contraction of the vaginal muscles that makes penetration — whether during sex, medical examination, or tampon insertion — painful, difficult, or impossible. It is not a conscious choice. It is the body's protective response — a learned pattern of muscle contraction that the nervous system has associated with anticipated pain, threat, or discomfort.
Vaginismus can be primary (present from the first attempt at penetration) or secondary (developing after a period of comfortable sex, often following trauma, painful gynaecological procedures, hormonal changes, or relationship breakdown).
It is not a sign that something is physically wrong with the vagina. It is a nervous system and muscle pattern — which means it responds to nervous system and muscle work.
The Hormonal and Nervous System Connection
The pelvic floor does not exist in isolation. It is directly connected to the nervous system — it tightens under sympathetic activation (stress, threat, anxiety) and releases under parasympathetic activation. Women with chronic stress, trauma histories, or anxiety consistently carry more tension in the pelvic floor.
Oestrogen also directly supports pelvic floor health — maintaining tissue elasticity, vaginal lubrication, and connective tissue integrity. As oestrogen declines in perimenopause, the pelvic floor becomes more vulnerable to both dysfunction and pain.
What Helps
Pelvic floor physiotherapy
This is the most important intervention for both hypertonic and hypotonic patterns — and for vaginismus. A specialist pelvic floor physiotherapist can assess which pattern is present (which is not always obvious) and provide targeted treatment. For hypertonic dysfunction and vaginismus, this typically involves internal manual therapy, relaxation exercises, and dilator therapy. For weakness, progressive strengthening work.
Nervous system work
For hypertonic patterns and vaginismus, nervous system regulation is as important as physical therapy. Breathwork, somatic therapy, EMDR for trauma-related vaginismus, and consistent parasympathetic practices all support the muscle release that physiotherapy is working toward.
Vaginal oestrogen in perimenopause
Local oestrogen (vaginal cream, pessary, or ring) directly supports tissue integrity and lubrication in the vagina and pelvic floor. It is absorbed locally with minimal systemic effect and can be used long-term. For women experiencing new pelvic pain, dyspareunia, or urinary symptoms in perimenopause, this is often the most direct intervention.
What not to do
Do not do Kegel exercises if you have a hypertonic pelvic floor or vaginismus — it worsens the problem. Seek assessment first.
Frequently Asked Questions
Is pelvic pain during sex normal?
No — pain during sex is not normal and should not be dismissed. It is common, but common is not the same as normal. Dyspareunia (pain during sex) has specific, treatable causes including hypertonic pelvic floor, vaginismus, endometriosis, vulvodynia, and oestrogen-related changes. Assessment by a pelvic floor physiotherapist or gynaecologist is the appropriate next step.
Can vaginismus be treated?
Yes — vaginismus responds well to treatment. Pelvic floor physiotherapy, graduated dilator therapy, and nervous system work have high success rates. The process takes time and requires consistent engagement, but the majority of women who receive appropriate treatment can achieve comfortable penetration.
Does the pelvic floor get weaker after menopause?
Oestrogen decline in perimenopause and menopause reduces tissue elasticity and connective tissue support in the pelvic floor. Pelvic organ prolapse and urinary incontinence become more common. Pelvic floor physiotherapy, local vaginal oestrogen, and progressive strength training (which supports the whole connective tissue system) all help maintain function.
