Erectile dysfunction, loss of libido and low sexual frequency increase the risk of cardiovascular disease in men with low testosterone.

INTRODUCTION

Testosterone deficiency increases the cardiovascular disease (CVD) risk.

AIM

To evaluate the effect of erectile dysfunction (ED), sexual frequency and hypogonadal symptoms on CVD risk.

METHODS

A total of 395 hypogonadal men aged 45-74 years were surveyed using the Androgen Deficiency in the Aging Male and the International Index of Erectile Function.

MAIN OUTCOME MEASURES

The 10-year CVD risk was measured with the Framingham Risk Score. Logistic regression was performed to obtain the odds ratios of sexual function and hypogonadal symptoms for a 10-year CVD risk ≥20% (high risk).

RESULTS

The mean age was 56.1 ± 6.7 years. The mean 10-year CVD risk of the whole cohort was 18.1% ± 11.4%, while 131 subjects (33.2%) were classified as high risk. Logistic regression revealed that ED severity was associated with CVD risk [OR = 2.37 (CI 1.24-4.51) for mild-to-moderate ED, OR = 4.39 (1.78-8.43) for moderate ED and OR = 12.81 (4.65-26.11) for severe ED]. Compared to sexual frequency <1 per month, sexual frequency ≥4 decreased the risk of high CVD risk [OR = 0.35 (0.23-0.780)]. Loss of libido [OR = 2.95 (1.91-4.12)] and less strong erection [OR = 3.87 (CI 2.11-4.95)] increased the risk of high CVD risk. All remained significant after adjustment for age and testosterone.

CONCLUSIONS

ED, decreased sexual frequency and loss of libido predict a high 10-year CVD risk in hypogonadal men.
