# Sexuality and Reproductive Health After Disability

## Introduction

Sexuality is a fundamental aspect of human identity and well-being that persists after the onset of disability. Despite its importance, sexual health remains one of the most under-addressed topics in rehabilitation medicine. Physiatrists are uniquely positioned to initiate conversations, provide education, and coordinate care related to sexual function, fertility, and intimacy for persons with disabilities. A proactive, patient-centered approach is essential.

## Barriers to Addressing Sexuality in Rehabilitation

**Clinician discomfort**: lack of training, embarrassment, and uncertainty about how to initiate the conversation. **Patient reluctance**: fear of judgment, cultural taboos, and assumption that clinicians will raise the topic. **Systemic barriers**: time constraints, lack of privacy in rehabilitation settings, and absence of standardized protocols. **Societal attitudes**: pervasive myths that persons with disabilities are asexual, childlike, or incapable of fulfilling sexual relationships.

The **PLISSIT model** provides a structured framework: Permission, Limited Information, Specific Suggestions, Intensive Therapy.

## Neurophysiology of Sexual Function

**Sexual arousal** involves coordinated interplay of central (cortical, limbic) and peripheral (autonomic, somatic) pathways. **Psychogenic arousal**: mediated via thoracolumbar sympathetic outflow (T11-L2); triggered by cognitive and sensory stimuli above the injury level. **Reflexogenic arousal**: mediated via sacral parasympathetic pathways (S2-S4); triggered by direct genital stimulation. **Ejaculation in males**: emission phase (T11-L2 sympathetic) and expulsion phase (S2-S4 somatic via pudendal nerve).

**Orgasm**: complex central phenomenon; may be preserved, altered, or experienced differently after neurological injury.

| Pathway | Spinal Level | Function | Preserved In |
|---------|-------------|----------|-------------|
| Psychogenic arousal | T11-L2 (sympathetic) | Arousal from cognitive/sensory stimuli | Incomplete LMN injuries |
| Reflexogenic arousal | S2-S4 (parasympathetic) | Arousal from direct genital stimulation | UMN injuries (above conus) |
| Emission | T11-L2 (sympathetic) | Seminal emission in males | Incomplete injuries |
| Ejaculation (expulsion) | S2-S4 (somatic/pudendal) | Forceful expulsion | Intact sacral arc |

## Sexual Dysfunction After Spinal Cord Injury

### Males

**Erectile dysfunction**: reflexogenic erections preserved in UMN injuries (above conus); psychogenic erections may be preserved in incomplete LMN injuries. **Ejaculatory dysfunction**: affects 90-95% of men with SCI; anejaculation is the most common problem. Fertility is significantly impaired due to ejaculatory failure, poor semen quality (impaired motility, abnormal morphology), and elevated scrotal temperature. **Retrograde ejaculation** may occur in incomplete injuries.

### Females

Lubrication parallels erection physiology: reflexogenic (S2-S4) and psychogenic (T11-L2) components. **Menstruation** typically resumes within 6 months after SCI following initial amenorrhea. Fertility is generally preserved; pregnancy is achievable and safe with appropriate medical management. Orgasm reported in 50% of women with SCI; may involve non-genital erogenous zones above the injury level.

## Sexual Dysfunction in Other Rehabilitation Populations

### Traumatic Brain Injury

Changes in libido (increased or decreased), disinhibition, inappropriate sexual behavior. Executive dysfunction affecting relationship skills, communication, and judgment. Hormonal disruption: **post-traumatic hypopituitarism** causing hypogonadism in up to 25% of moderate-severe TBI.

### Stroke

Sexual dysfunction reported in 50-75% of stroke survivors. Contributing factors include hemiparesis, sensory loss, spasticity, fatigue, depression, and medication side effects. Fear of recurrent stroke during sexual activity is common but generally unfounded.

### Multiple Sclerosis

Primary dysfunction: neurogenic impairment of arousal, sensation, and orgasm. Secondary dysfunction: spasticity, fatigue, bladder and bowel concerns, pain. Tertiary dysfunction: psychosocial factors including altered self-image and relationship changes.

## Assessment

**Routine screening**: integrate sexual health questions into the rehabilitation intake and follow-up assessments. Use validated tools: **Sexual Interest and Satisfaction Scale (SIS)**, **Female Sexual Function Index (FSFI)**, **International Index of Erectile Function (IIEF)**. Assess contributing factors: medications (antidepressants, antihypertensives, antispasmodics), comorbid conditions, psychological status, and relationship dynamics. Evaluate for autonomic dysreflexia risk during sexual activity in patients with SCI at T6 and above. Consider endocrine evaluation: testosterone, prolactin, thyroid function when indicated.

## Management Strategies

### Pharmacological

**Phosphodiesterase-5 inhibitors** (sildenafil, tadalafil): first-line for erectile dysfunction; effective in SCI and stroke. **Intracavernosal injections** (alprostadil, papaverine): second-line for erectile dysfunction. **Vacuum erection devices**: non-pharmacological option with constriction ring. **Topical estrogen or lubricants**: for vaginal dryness and discomfort. Medication review: consider switching antidepressants (e.g., from SSRIs to bupropion) to reduce sexual side effects.

### Fertility Interventions for Males with SCI

**Penile vibratory stimulation (PVS)**: first-line for ejaculation in UMN injuries; success rate 60-80%. **Electroejaculation (EEJ)**: second-line; performed under anesthesia or sedation; autonomic dysreflexia prophylaxis required. **Surgical sperm retrieval**: testicular sperm extraction (TESE) or microsurgical epididymal sperm aspiration (MESA) when PVS and EEJ fail. **Assisted reproductive technologies**: intrauterine insemination (IUI) or in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI). ![Stepwise fertility management algorithm for males with spinal cord injury](male-fertility-sci-algorithm.png)

### Pregnancy and Delivery Considerations

Women with SCI can safely carry pregnancies with appropriate multidisciplinary monitoring. **Autonomic dysreflexia** during labor is the most dangerous complication in women with injuries at T6 and above; epidural anesthesia is recommended. Higher risk of urinary tract infections, pressure injuries, DVT, and preterm labor. Labor may be painless below the injury level; patients must be educated on recognizing signs of labor (uterine palpation, timing contractions). Breastfeeding is possible but may require support for positioning and latch.

## Psychosocial Considerations

Address **body image** changes, grief related to altered sexual function, and impact on partner relationships. Normalize the process of sexual rediscovery and adaptation after disability. Encourage exploration of non-genital erogenous zones and alternative expressions of intimacy. Referral to sex therapy or couples counseling when indicated. Peer support and peer mentoring from individuals with lived experience.

## Key Clinical Pearls

Use the PLISSIT model to structure conversations: begin by giving Permission to discuss sexuality, provide Limited Information, offer Specific Suggestions, and refer for Intensive Therapy as needed. Physiatrists should proactively raise the topic of sexuality; patients consistently report they want this information but wait for clinicians to initiate. Autonomic dysreflexia is a critical safety consideration during sexual activity and labor for patients with SCI at T6 and above. Female fertility is generally preserved after SCI; male fertility is significantly impaired but addressable with assisted reproductive techniques. Medication side effects are a common and modifiable cause of sexual dysfunction across all rehabilitation populations.
