Assessment of sexual function and quality of life in patients with lower limb amputations

Diseases causing disabilities lead to sexual dysfunction. However, studies that evaluate sexual functions in patients with traumatic lower limb amputations (LLA) are limited and controversial.

The objective is to evaluate sexual functions in male patients with LLA and to identify factors that might contribute to sexual dysfunction. The hypothesis is that male patients with LLA would experience worse sexual and emotional functioning and consequently emotional impairment that consequently influenced the sexual function.

Sixty men with traumatic LLA and 60 healthy men were assessed according to the International Index of Erectile Function (IIEF) scoring system. Emotional state was assessed by the Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI), and the quality of life by the Short Form-36 Health Survey (SF-36).

Patients had significantly lower scores in the IIEF total score and subscores in comparison with the controls. Intercourse satisfaction scores were significantly higher (p< 0.05) in patients with trans-tibial amputation than in those with trans-femoral amputation. BDI and BAI scores negatively correlated with erectile function, sexual desire, intercourse satisfaction, overall satisfaction and total IIEF scores. The mental and physical scores of SF-36 significantly correlated with some of the sub scores and IIEF total scores. The power of statistical analysis for study population was 100% according to the given effect size (α= 0.01).

The present study suggests that the LLA leads to impairments in the sexual function and quality of life in male patients. Also, sexual dysfunction in patients is strongly associated with emotional state, pain, level of amputation and quality of life.
