Sexual dysfunction is a recognised concern after rectal cancer surgery, affecting many patients to varying degrees. Understanding the causes, expected changes, and available treatment options can help you manage this aspect of recovery and improve quality of life.
Causes of Sexual Dysfunction After Rectal Cancer Surgery
Rectal cancer surgery can affect sexual function through a combination of physical and emotional factors. The pelvic region contains delicate nerve pathways responsible for sexual response and arousal. During surgery, these nerves may be affected, especially when removing tumours near the lower rectum.
Key contributors include:
Nerve damage: The autonomic nerves controlling sexual function lie close to the rectum and may be affected during cancer removal.
Structural changes: Surgery can alter pelvic anatomy, affecting blood flow and sensitivity in the genital area.
Scar tissue formation: Healing tissues may create physical barriers that impact sexual comfort and function.
Hormonal changes: Some treatments, such as chemotherapy or radiotherapy, can affect hormone levels.
Types of Sexual Dysfunction After Rectal Cancer Surgery
Sexual difficulties can vary between men and women after rectal cancer treatment:
Erectile dysfunction in men: Difficulty achieving or maintaining erections due to nerve damage affecting blood flow to the penis
Reduced vaginal lubrication in women: Decreased natural moisture making intercourse uncomfortable or painful
Decreased sensation: Reduced feeling in genital areas due to nerve damage, affecting pleasure and arousal
Orgasmic difficulties: Problems reaching climax or changes in orgasm intensity for both men and women
Physical Changes That Affect Sexual Function After Rectal Cancer Surgery
Several physical changes following rectal cancer surgery can directly affect sexual function and comfort:
Altered blood flow: Surgical changes can reduce blood circulation to sexual organs, affecting arousal and response
Pelvic floor changes: Surgery may weaken or tighten pelvic floor muscles, creating discomfort during sexual activity
Stoma presence: Patients with colostomies may feel self-conscious or experience practical challenges during intimacy
Fatigue and pain: Recovery-related tiredness and discomfort can reduce interest in sexual activity
Treatment and Management Options
Many patients experience improvement over time, but targeted treatment can support recovery:
Medications for erectile dysfunction: Phosphodiesterase-5 inhibitors (such as sildenafil) may be prescribed for men when nerve function is partially preserved
Vaginal moisturisers and lubricants: These products may reduce dryness and discomfort during intimacy for women
Pelvic floor physiotherapy: Specialised exercises may be recommended to address muscle function and pain during sexual activity
When to See a Specialist
You should speak to your colorectal specialist if you experience:
Persistent Sexual Difficulties (Beyond 6-12 Months)
- Ongoing erectile dysfunction or difficulty achieving orgasm
- Persistent vaginal dryness or discomfort during intimacy
- Continued loss of sexual sensation
- Ongoing pain during sexual activity
New or Worsening Symptoms
- New onset of erectile difficulties or reduced sensation
- Increased pain or discomfort during sexual activity
- Sudden changes in sexual function that were not present earlier
- Any unexpected changes affecting intimacy or sexual health
Conclusion
Sexual dysfunction is a recognised concern after rectal cancer surgery, and recovery timelines differ for each person. Some patients notice gradual improvement, while others may require additional support.
If you experience ongoing sexual difficulties or are unsure what to expect during rectal cancer surgery recovery, consult a colorectal specialist for guidance on management options and personalised care.
