Sex, Fertility and Relationships: The Subject Rehab Skips

Sex, fertility and relationships after spinal cord injury: the subject rehab skips

Rehabilitation after a spinal cord injury covers bladder, bowel, skin, transfers, wheelchair skills and equipment in detail, repeatedly, with written plans and competency sign-offs.

Sex gets a pamphlet.

When people with spinal cord injury are asked what matters to them, sexual function consistently ranks among the highest priorities — frequently above walking. When they are asked whether anybody addressed it properly, the answer is frequently no. The gap between those two things is one of the clearest failures in the field, and it is not because the information does not exist. It exists, it is reasonably good, and it does not get delivered.

Two facts that should be said at the top, because they are the ones most often not said and the ones that change people’s lives.

Queensland Health’s guidance on pregnancy after spinal cord injury states it plainly: “A spinal cord injury doesn’t alter the likelihood of becoming pregnant.” Women with spinal cord injury who do have fertility problems are treated the same way as anybody else, with similar success rates from fertility treatment.

Men with spinal cord injury can father children. Ejaculation is frequently affected and sperm quality is often impaired, but established pathways exist and they work.

A great many people spend years believing the opposite, because nobody told them otherwise.

This is written by a New South Wales provider that supports people with spinal cord injury. We are not a sexual health or obstetric service and nothing here is medical advice. This guide exists because the subject is systematically under-addressed, and because people are entitled to accurate information about their own bodies.

The physiology: two arousal pathways, and injuries affect them differently

Sexual arousal runs on two separate neural pathways, and understanding which one an injury affects explains most of what follows.

Reflexogenic arousal runs through the sacral reflex arc at S2 to S4. It is triggered by direct physical stimulation and does not require any input from the brain. An injury above the sacral segments leaves this reflex intact but disconnected from conscious control — so physical stimulation can produce an erection or lubrication, without any sense of arousal accompanying it, and without the person being able to initiate or sustain it by thought.

Psychogenic arousal runs through a sympathetic pathway from roughly T11 to L2. It is triggered centrally — by thought, by sight, by anticipation. An injury above that outflow blocks it. An injury below it may leave it intact.

The consequence is a neat inversion that catches people out:

So someone with a high cervical injury may have reliable reflex erections they cannot control or initiate mentally, while someone with a cauda equina injury may feel fully aroused with no physical response at all. These are opposite problems requiring opposite approaches, which is why generic advice fails.

Incomplete injuries, which are the majority in Australia, produce mixed and individual patterns. The only way to know is a proper assessment.

Sensation, pleasure and orgasm

The assumption that a spinal cord injury ends sexual pleasure is wrong, and the reasons are worth understanding.

Sensation reorganises. Many people report that areas at and above the injury level become more sensitive after injury — the neck, ears, lips, shoulders, chest, hands where function remains. This is not imagination or compensation in a pejorative sense; it reflects genuine changes in how the nervous system processes sensation when input from large parts of the body stops arriving.

Orgasm remains possible for a substantial proportion of people with spinal cord injury, including some with complete injuries. It is reported less frequently and often takes longer than before injury, and the experience is frequently described as different — more diffuse, less localised, sometimes felt throughout the body rather than in the genitals. Research in this area has established clearly that it happens, which is the important point, because people are commonly told or assume it cannot.

The vagus nerve does not pass through the spinal cord, which is one proposed route by which sensation from the cervix and pelvic organs may reach the brain in people with complete spinal cord injuries.

What follows practically is that exploration is worthwhile, that the map of what works is individual and has to be redrawn, and that this takes time and a willing partner or a willingness to work it out alone. It also means that a clinician who says “that’s not possible with your injury” is not giving reliable information.

Men: erectile function, ejaculation and fertility

Erections. Reflex erections are common in injuries above the sacral segments, though often not sustainable or not occurring when wanted.

The treatment options are well established and generally effective:

• PDE5 inhibitors — sildenafil, tadalafil and related medications — have a good evidence base specifically in spinal cord injury and are usually first-line. Note the important interaction flagged in autonomic dysreflexia guidance: if somebody has taken one of these within 24 hours, nitrates must be avoided in managing a dysreflexia episode. This is worth the person knowing and telling paramedics.
• Vacuum erection devices.
• Intracavernosal injection, which is highly effective where tablets are not.
• Intraurethral preparations.
• Penile implants, for selected cases.

Ejaculation is affected far more often than erection. Anejaculation — the inability to ejaculate — is common, particularly in higher injuries. Retrograde ejaculation into the bladder also occurs.

Where ejaculation is required for fertility, two established techniques exist:

• Penile vibratory stimulation, which uses a high-amplitude vibrator to trigger the ejaculatory reflex. It works in a substantial proportion of men with injuries above the relevant level and can often be done at home after training. It can trigger autonomic dysreflexia, which is why the first attempts are supervised and why blood pressure is monitored.
• Electroejaculation, performed in a clinical setting where vibratory stimulation does not work.

Fertility. Sperm numbers are often reasonably preserved after spinal cord injury, but motility and viability are commonly impaired. The suggested reasons include raised scrotal temperature from prolonged sitting, stasis from infrequent ejaculation, recurrent urinary tract infection, changes in seminal fluid composition, and antisperm antibodies.

What matters is that this is a solvable problem in most cases. Sperm retrieval combined with assisted reproduction — in particular intracytoplasmic sperm injection — achieves pregnancies routinely in this population. The pathway is: a referral to a fertility service with spinal cord injury experience, semen analysis, and a plan.

The practical advice that often gets missed: regular ejaculation appears to improve sperm quality by reducing stasis, so a man planning to father children may be advised to establish a regular pattern well before trying to conceive.

Women: fertility, contraception and pregnancy

Fertility is generally preserved, and this is the single most important message in this guide.

What happens after injury is that periods commonly stop temporarily. Queensland Health’s guidance reports amenorrhoea affecting around 85 per cent of women with cervical or high thoracic injuries and roughly 50 to 60 per cent overall, typically lasting six to twelve months. Periods return in 50 to 90 per cent of women, usually without lasting effects on fertility.

The practical implication is immediate and important: a woman whose periods have stopped after a spinal cord injury is not necessarily infertile, and contraception is still required if pregnancy is not wanted. People get caught by this.

Contraception needs a proper conversation, because the usual calculus changes. Combined hormonal contraception carries a thrombosis risk, and reduced mobility after spinal cord injury raises baseline thrombosis risk — so the balance of options may differ from what a woman would have been offered before injury. Barrier methods may be harder to manage with limited hand function. An intrauterine device may be a good option but insertion can trigger autonomic dysreflexia in injuries at or above T6 and should be planned accordingly. This is a discussion for a clinician who understands both contraception and spinal cord injury.

Cervical screening remains necessary and is frequently skipped because it is physically difficult. Self-collection is available under the National Cervical Screening Programme and removes the positioning and speculum barriers.

Pregnancy, labour and the thing that must not be missed

Pregnancy after spinal cord injury is achievable and commonly goes well. It is higher-risk, and the risks are specific and manageable with planning. Queensland Health’s guidance sets them out.

During pregnancy:

• Bladder. Reduced bladder capacity as the uterus grows, more frequent catheterisation needed, more bladder spasm. Two specific traps: urinary tract infection can trigger premature labour, and urinary leakage can be mistaken for the waters breaking — and vice versa.
• Bowel. Worsening constipation and impaction risk from uterine pressure on the colon and from hormonal change. The bowel programme will need adjusting.
• Respiratory. The growing uterus restricts lung expansion, increasing breathlessness and pneumonia risk, particularly in tetraplegia where reserve is already limited.
• Circulation. Increased deep vein thrombosis risk, swelling, and episodes of low blood pressure.
• Skin. Greater pressure injury risk from weight gain, changed weight distribution and reduced mobility. Cushion and seating review during pregnancy is sensible.
• Spasticity. May increase, and medication may need review — including on safety in pregnancy.
• Transfers and balance. A shifting centre of gravity makes transfers harder, and support needs commonly increase through the pregnancy. This is a reason to review an NDIS plan during pregnancy rather than after.
• Fatigue, particularly in the third trimester.
• Positioning. Lying flat on the back should be avoided later in pregnancy, because the enlarged uterus reduces venous return.
• Autonomic dysreflexia, a particular concern at T6 and above.

Labour — and this is the critical one. Spinal cord injury does not affect when labour starts, because uterine contractions are driven hormonally rather than neurologically.

What it affects is whether the woman knows.

Women with injuries above roughly T10 often feel contractions only as vague abdominal discomfort, or not at all. Which means labour can begin, and progress, unrecognised. The risk of an unattended delivery is real.

The signs that may substitute for feeling contractions, per the Queensland guidance: a mucous show, the waters breaking, backache, increased spasticity, bladder spasm, autonomic dysreflexia, pain felt above the injury level, and changes in breathing.

What should be in place: teaching the woman to palpate her own uterus for tone and contractions where she can; regular clinical checks of uterine tone, cervical dilation and effacement as term approaches; and consideration of foetal and contraction monitoring. Induction may be considered specifically to avoid unrecognised labour — though the guidance notes this is more complex at T6 and above because of dysreflexia risk.

Autonomic dysreflexia in labour. Contractions raise blood pressure, so dysreflexia frequently occurs during labour and delivery in women with injuries at or above T6. It can cause foetal distress. The guidance notes that where dysreflexia is not controlled, immediate delivery of the baby and placenta is considered essential.

Distinguishing dysreflexia from pre-eclampsia is critical and the guidance gives the key discriminator: in autonomic dysreflexia the heart rate may slow, whereas pre-eclampsia often produces a rapid heart rate. The management differs fundamentally — dysreflexia is managed to allow the pregnancy to continue, while pre-eclampsia may prompt early delivery because of risk to mother and baby. Getting this wrong in either direction has consequences.

Anaesthesia. The guidance is that every woman should discuss pain relief with an anaesthetist before labour, regardless of her level of sensation and regardless of planned mode of delivery — and that this matters especially at T6 and above. An epidural is the preferred option because it is more effective at controlling autonomic dysreflexia. Blood-pressure-lowering drugs can cause sudden hypotension that may reduce blood flow to the baby.

Mode of delivery is not determined by the injury. Some women deliver vaginally without difficulty; others need vacuum or forceps assistance because the muscles used for pushing may not function. Caesarean section is performed more often in women with spinal cord injury, frequently because of skeletal factors — spinal curvature, previous pelvic fracture, hip dislocation — that reduce abdominal space rather than because of the neurological injury itself.

The single most important thing: a woman with a spinal cord injury who is pregnant or planning pregnancy needs her obstetric team and her spinal service talking to each other, with a written plan, well before delivery. Not at 38 weeks. The plan should cover dysreflexia recognition and management, anaesthetic approach, labour detection, bladder and bowel management, and positioning. Many obstetric teams have never managed this, and the spinal service holds knowledge the obstetric team needs.

The practicalities nobody writes down

Bladder. Empty before sex. For an indwelling urethral catheter, options include taping it back along the shaft, or removing and replacing it — discuss with the treating service which is appropriate. A suprapubic catheter is substantially less intrusive sexually, which is one of its genuine advantages and a legitimate factor in choosing between methods.

Bowel. Completing the bowel programme beforehand reduces the risk of an accident, which is the thing people fear most. This is one of the reasons transanal irrigation and colostomy are valued by people who have them — more complete emptying means more confidence.

Autonomic dysreflexia. Intercourse and ejaculation are listed triggers in clinical guidance, as is penile vibratory stimulation. Anybody with an injury at or above T6 should know this, know the signs, and know the response — sit up, loosen clothing, stop the stimulus.

Skin. Friction and sustained pressure during sex can damage skin that cannot feel it. Check afterwards. Positioning and padding help.

Spasticity. Can be triggered by position and stimulation. Sometimes manageable with timing of medication, positioning or pre-activity stretching.

Positioning and equipment. Pillows, wedges, bed height, bed rails, a profiling bed. Entirely legitimate things to discuss with an occupational therapist, and the awkwardness of raising it is worth getting past.

Temperature. Thermoregulation is impaired after spinal cord injury. Room temperature matters more than it used to.

Planning versus spontaneity. This is the honest loss. Sex after spinal cord injury frequently requires preparation, and that is a real change that people grieve. What helps is reframing the preparation as part of it rather than an obstacle to it, and partners who treat it as ordinary.

Relationships, and the carer problem

The biggest relationship risk after spinal cord injury is not the sex. It is what happens when a partner becomes the primary carer.

When one person in a couple is doing their partner’s bowel programme, catheterisation, showering and transfers, the relationship structure changes whether anybody wants it to or not. The dynamic becomes clinical. The person being cared for loses equality in the relationship and often feels like a burden. The partner becomes exhausted and sometimes resentful, and then feels guilty for the resentment.

The AlphaBeta report prepared for SpinalCure Australia found that up to 70 per cent of people with spinal cord injury have an informal carer, with an informal care opportunity cost of $5.6 billion.

Which produces the most practical argument in this entire guide: adequate funded support protects relationships. A plan that funds paid workers for intimate care means the partner can be a partner. A plan that does not means the partner does it, and the relationship carries a load it was not built for.

If you are negotiating a plan and a partner is currently providing intimate personal care, say so explicitly and say what it is costing the relationship. It is a legitimate and relevant consideration, and it is rarely raised because people are embarrassed.

Other things worth naming:

New relationships after injury are entirely ordinary, and people worry disproportionately that they are not. Dating happens. Relationships form. The practical obstacles are mostly logistical — accessible venues, transport, somewhere to go — rather than about desirability.

Disclosure. When and how to tell a new partner about bladder and bowel management is a personal decision with no right answer. Most people find that earlier and more matter-of-fact works better than later and loaded.

Peer input is more useful here than professional input, consistently. Other people with spinal cord injury have solved these problems and will talk about them frankly in a way that a clinic appointment does not.

Consent and safety. People with disability experience sexual violence at substantially elevated rates, which was documented extensively by the Royal Commission into Violence, Abuse, Neglect and Exploitation of People with Disability. Somebody who depends on others for intimate physical care is in a position of particular vulnerability. Workers providing intimate care have clear professional boundaries and any breach of them is reportable. If something has happened, the NDIS Quality and Safeguards Commission is on 1800 035 544, and 1800RESPECT is on 1800 737 732.

Where to get proper help

• The spinal unit or spinal outreach service. Ask directly. Many have somebody with specific expertise, and the question will not surprise them.
• A sexual health physician or a rehabilitation physician with spinal cord injury experience.
• A fertility service, for men needing sperm retrieval or couples needing assisted reproduction. Ask whether they have experience with spinal cord injury.
• An obstetric service, early, for anyone pregnant or planning pregnancy, with explicit contact between them and the spinal service.
• A sexuality counsellor or psychosexual therapist, ideally one experienced in disability.
• Family Planning services in your state for contraception advice.
• Spinal Cord Injuries Australia for peer support, which for this subject is frequently the single most valuable resource available.
