Impact of Androgens on Sexual Function in Women With Rectal Cancer - A Prospective Cohort Study

Postmenopausal sexual function and steroid hormone levels: a hospital-based cross-sectional study

OBJECTIVE

Steroid hormone levels, particularly androgens, play an important role in sexual function in premenopausal women, but this relationship is not so well determined after menopause. This study aimed to assess the association between steroid hormone levels and sexual function in postmenopausal women.

METHODS

A total of 84 postmenopausal women with intact ovaries, who had never used systemic hormone therapy, were enrolled in a cross-sectional study. Sexual function was assessed using the Female Sexual Function Index (FSFI) questionnaire and serum levels of steroid hormones were quantified by gas chromatography and tandem mass spectrometry. Associations between estradiol, testosterone, dehydroepiandrosterone, androstenedione and FSFI domain scores were evaluated.

RESULTS

After adjustment for confounding variables, the analysis revealed a statistically significant association between androstenedione and overall sexual function (β = 1.23, 95% confidence interval [CI] [0.37; 1.98], p = 0.010), arousal (β = 0.19, 95% CI [0.02; 0.37], p = 0.034), orgasm (β = 0.33, 95% CI [0.15; 0.45], p = 0.001) and satisfaction (β = 0.25, 95% CI [0.11; 0.36], p = 0.001). No associations were found between the other hormones and FSFI domains.

CONCLUSION

The main finding of this study is the association of androstenedione with sexual function in postmenopausal women, not verified for other steroid hormones. Further studies are necessary to determine the importance of androstenedione for postmenopausal sexual function.

Sexual Functioning in Female Patients Undergoing Surgical Treatment for Colorectal Cancer-A Single-Center, Prospective Triple Timepoint Yearly Follow-Up

The study was aimed at assessing the quality of sexual functioning in female patients having undergone surgical treatment for cancer depending on the type of surgery. The prospective cohort consisted of 48 female patients (23 patients with stoma [A2] and 25 patients with maintained continuity of the GI tract [A1]). Study methods included a diagnostic survey and the analysis of medical records of patients. Research tools consisted of a standardized FSFI questionnaire and a proprietary form for evaluation of sociodemographic data. Measurements were performed at threetimepoints: On the day before the surgery (Measurement I) as well as six and 12 months after the surgery (Measurements II and III, respectively). Statistically significant differences in results were observed in Measurements II and III in the subscales of arousal (II:p = 0.0068, III:p = 0.0018), lubrication (II:p = 0.0221, III:p = 0.0134), orgasm (II:p = 0.0044, III:p = 0.0021), satisfaction (II:p = 0.0021, III:p = 0.0433), and pain/discomfort (II:p = 0.0343, III:p = 0.0473). In all cases, lower scores corresponding to lower quality of sexual functioning were observed in patients in whom stoma had been performed. Statistically significant differences in sexual functioning were observed at Measurements II and III in each group, with the results being significantly (p > 0.05) worse in patients having undergone Hartmann’s procedure or abdominoperineal resection). Variables significantly affecting self-assessed sexual satisfaction included marital status, age, and modality of neoadjuvant treatment. Restoration of the continuity of the gastrointestinal tract is a chance for better self-assessment of the patient’s quality of life as regards sexual functioning.
