Benign perianal diseases such as chronic anal fissure, hemorrhoidal disease, and cryptoglandular anal fistula may negatively affect female sexual function through pain, bleeding, discharge, discomfort, and impairment in quality of life. Although improvement in male sexual function after surgery for benign anorectal disorders has been reported, data regarding female sexual function remain limited.

This prospective observational cohort study aims to evaluate changes in Female Sexual Function Index (FSFI) scores following surgical treatment of benign perianal diseases. Female patients undergoing surgery for chronic anal fissure, hemorrhoidal disease, or cryptoglandular anal fistula will be assessed preoperatively and at postoperative 3 and 6 months using the FSFI, Cleveland Clinic Incontinence Score (CCIS/Wexner), and Visual Analog Scale (VAS).

The primary objective is to determine whether female sexual function improves following surgical treatment. Secondary objectives include evaluating the relationship between symptom improvement, continence status, pain reduction, and changes in female sexual function.

Female sexual function is a multidimensional concept influenced by physical, psychological, and social factors. Benign perianal diseases are common surgical conditions that may adversely affect sexual function through chronic pain, bleeding, discharge, prolapse, discomfort, embarrassment, and reduced quality of life.

Previous studies have demonstrated impaired sexual function among patients with anorectal disorders. Furthermore, improvement in male sexual function following surgical treatment of benign anorectal diseases has been reported. However, prospective data regarding female sexual function after surgical treatment of benign perianal diseases remain scarce.

This single-center prospective observational cohort study will be conducted at Gazi University Faculty of Medicine. Sexually active women aged 18 to 70 years undergoing surgery for chronic anal fissure, hemorrhoidal disease, or cryptoglandular anal fistula will be enrolled.

Participants will complete the Female Sexual Function Index (FSFI), Cleveland Clinic Incontinence Score (CCIS/Wexner), and Visual Analog Scale (VAS) questionnaires before surgery and at postoperative 3 and 6 months.

The primary outcome will be the change in total FSFI score from baseline to postoperative 6 months. Secondary outcomes will include changes in FSFI at 3 months, changes in CCIS and VAS scores, and subgroup analyses according to disease type and symptom severity.

The investigators hypothesize that successful surgical treatment of benign perianal diseases will result in significant improvement in female sexual function and that this improvement will correlate with reductions in pain and disease-related symptoms.
