Sexual Dysfunction in Female Rectal and Anal Cancer Survivors: Pathophysiology, Clinical Management, and Integration into Survivorship Care

Background: Female Sexual dysfunction (FSD) is a common but under-recognized outcome of rectal and anal cancer treatment. While survival has improved, sexual health remains insufficiently addressed in survivorship care, warranting a multidisciplinary perspective. Methods: A narrative review of studies published between 2000 and 2025 was conducted, including clinical trials, cohort studies, and guideline documents addressing female sexual dysfunction after anorectal cancer treatment. Articles that were not pertinent to the research topic, outdated, or methodologically inadequate were excluded from the analysis. Results: Over 60% of female survivors experience FSD, including decreased libido, vaginal dryness, dyspareunia, and arousal difficulties. Causes include hormonal deficiency, nerve injury, and radiation fibrosis, compounded by psychological distress, altered body image, stoma-related stigma, and communication issues. The FSFI is commonly applied but lacks specificity for this population. Geographic disparities persist, with greater stigma and limited care access in low- and middle-income countries. Emerging therapies, such as immunotherapy, may mitigate FSD risk, though evidence is scarce. Conclusions: FSD after anorectal cancer is highly prevalent and significantly impacts quality of life, yet remains under-assessed in follow-up care. Multidisciplinary, culturally sensitive strategies integrating screening, psychosexual support, and tailored rehabilitation are urgently needed. Future research should address sexual outcomes more systematically, particularly in novel treatment contexts.
