RESUMEN
Objective: To investigate the sexual behavior and sexual function of the male partners of breast cancer patients and their potential relationship with socio-demographic and clinical variables. METHODS: In this cross-sectional study, we conducted an investigation among 196 male partners (aged 23ï¼59 years) of breast cancer patients between May 2020 and October 2020. We completed the Male Sexual Function Questionnaire (BSFI) by online and telephone interview with the subjects and collected relevant socio-demographic and clinical variables. RESULTS: The average age of the interviewees was (46.13 ± 7.75) years old, and the mean duration of the patients' breast cancer was (1.58 ± 0.48) years at the time of the investigation. The incidence rate of sexual dysfunction in the male partners of the patients was dramatically higher after the onset of breast cancer than before it (49.76% vs 9.68%, P < 0.01). Low libido was found to be the main type of sexual dysfunction (38.3%) among the male subjects, with an even high incidence rate among those whose wives received mastectomy (OR = 5.533, P = 0.017, 95% CI: 1.366ï¼22.412) and radiotherapy (OR = 3.439, P < 0.044, 95% CI: 1.058ï¼11.171) and significantly correlated with age (OR = 1.134, P = 0.001, 95% CI: 1.053ï¼1.222). CONCLUSIONS: Breast cancer and its treatment methods may affect the sexual function of the male partners of the patients. It is necessary for doctors to pay attention to the factors affecting the sexual function of the patients and their partners so as to take appropriate intervention measures.
