As men age, their estrogen levels gradually rise, while testosterone levels fall. Anti-cancer coupounds called indoles can help strike a balance. Cruciferous vegetables like broccoli are rich in indoles, which boost testosterone production by breaking down and flushing the system of excess estrogen, which inhibits the production of male sex hormones. In one study, supplementing with indole-3-carbinol from cruciferous vegetables for just 7 days cut the estrogen hormone estradiol in half for men. Another study found indole supplementation significantly increased urinary excretion of estrogens.
ED is caused by vascular, hormonal, neurogenic, pharmacological, or psycho-genic factors. Performance anxiety where the person fears failing in a sexual scenario is a common psychogenic cause for ED.3 Neurogenic causes are related to diseases like Alzheimer's, Parkinson's, stroke or spinal cord injuries. Radical removal of the prostate (also called prostatectomy) is the cause of nerve-related ED as nerve injury is possible despite advances in surgical methods.4
Intensive lifestyle changes that include a Mediterranean type diet, circuit-type resistance training, with 15- to 60-second rest between sessions has shown to improve erectile score in a randomized trial. Men in the intervention group had a significant decrease in glucose, insulin, low-density lipoprotein cholesterol, triglycerides, and blood pressure, and a substantial increase in HDL cholesterol.15
In fact, one common reason many younger men visit their doctor is to get erectile dysfunction medication. Often, men with erectile dysfunction suffer with diabetes or heart disease, or may be sedentary or obese, but they don’t realize the impact of these health conditions on sexual function. Along with erectile dysfunction treatment, the doctor may recommend managing the illness, being more physically active, or losing weight.
