A new study from a group of physicians from Northwestern University and Brigham and Women’s Hospital in Boston found that erectile failure may be the result of a hormonal imbalance that may be triggered by the presence of certain chemicals in the body.
The study was published in the journal Archives of Sexual Behavior.
The researchers used blood samples from 1,500 men with erectile problems and 500 healthy men, ages 21 to 64.
Researchers also measured testosterone levels in the blood.
They found that the men with low testosterone levels were more likely to have low levels of erectile functioning, as measured by a sexual function index (EFVI).
“The findings suggest that testosterone and other male hormones are involved in the mechanism that underlies erectile function decline,” said Dr. William Schaffer, the study’s lead author and professor of medicine and pediatrics at Northwestern University Feinberg School of Medicine.
“The effect of this imbalance is reversible and the men who have been on testosterone therapy for a long time are at increased risk of having erectile difficulties,” Schaffer said.
The study found that low testosterone was linked to an increased risk for both erectile disorder and erectile defect in men.
In addition, there was an increased likelihood of a history of diabetes, hypertension and coronary artery disease.
According to the researchers, men who were low on testosterone had a higher risk of developing erectile dysfunctions.
In fact, men with lower testosterone levels had a lower risk of erectil problems.
However, these men had lower rates of erect failure, and they had lower EFVI scores than their testosterone-lowering peers.
In other words, low testosterone may be a key factor in the development of erectility problems.
“Low testosterone may cause the normal, underlying hormonal imbalance in the human body that leads to problems with sexual function,” said Schaffer.
“Our study suggests that testosterone deficiency is an important factor in erectile problem development,” he said.
