Glucose intake and the rise of blood sugar may lower men's testosterone levels, a new study suggests.

A team of researchers examined the testosterone levels of 74 men who received a standard dose of glucose and were then administered an oral glucose tolerance test.

The researchers found that 42 men had normal glucose tolerance on the test, 23 had impaired glucose tolerance, and nine were newly diagnosed with type 2 diabetes.

Regardless of having normal glucose tolerance, prediabetes, or diabetes, the study authors found that the glucose solution the men ingested had lowered their testosterone blood levels by as much as 25 percent.

After two hours, the testosterone levels remained much lower than before the test in 73 of the 74 men.

Before the test, 66 men had normal testosterone levels, but 10 of these men became hypogonadal at least once during the test.

Based on this research, the study authors recommended that men who have low testosterone should have their hormone levels re-tested after an overnight fast.

The researchers reported their results at The Endocrine Society's 91st Annual Meeting in Washington, D.C.
