We all enjoy a nice, sweet treat every now and then. However, when we start overindulging in these desserts, that’s when it becomes a problem. It is a fact that sugar plays an important role in our daily intake, along with other whole foods that contain fiber, minerals, antioxidants as well as protein. But a big reason why we must consume it in moderation is because too much sugar can easily mess with your bodily functions. A recent study, according to the Endocrine Society news release, suggests that even small increases in blood sugar, levels that aren't high enough to be considered diabetes, could negatively impact a man's ability to father children and his sexual function. The research indicates that even these minor elevations in blood sugar are linked to problems with how sperm move and with getting or maintaining an erection. Blood Sugar's Impact Outweighs Age and Hormones Surprisingly, this research found that these subtle changes in a man's blood sugar might affect his fertility and sexual health more significantly than the natural decline in hormone levels that comes with getting older. For a long time, it was thought that age and hormone levels were the main drivers of a man's declining sexual health. However, this study suggests that these changes are more closely related to small increases in blood sugar and other body changes tied to metabolism. Lifestyle Choices Can Help The good news is that men can take active steps to protect or even improve their reproductive health. Making healthy lifestyle choices and getting appropriate medical care can make a big difference. This means that men have the power to help their bodies stay healthy in ways that support their sexual and reproductive well-being. Simple habits like eating a balanced diet, exercising regularly, and losing any extra weight can help keep blood sugar levels in a healthy range. To understand these effects, researchers followed a group of healthy men over several years. The study started in 2014 with 200 men, ranging in age from 18 to 85, and continued to track them until 2020. By the end of the study period, 117 of these men were still participating. During this time, researchers carefully looked at various aspects of the men's health. They examined changes in their sperm quality, hormone levels, ability to have erections, and indicators of their metabolic health. This included checking things like their body fat levels (measured by BMI) and, importantly, their blood sugar levels. Key Findings As the years passed, the men's hormone levels and general sperm characteristics mostly stayed within normal ranges. However, a significant finding emerged: sperm movement and erectile function saw a decline in men whose blood sugar levels went up, even if those levels were still below what's considered the diabetes threshold. This threshold is typically measured by a blood test called hemoglobin A1C, with 6.5% being the point for diabetes. The study also observed that while testosterone levels didn't directly affect a man's ability to get an erection, they did seem to influence his reported sexual desire. The researchers are hopeful that the information from this study will be valuable for doctors and their patients. They believe it can help create effective plans for men to maintain their sexual health. This research shows that it's within our control to support men's sexual and reproductive well-being, even as they age. It's worth noting that these findings were first shared at a medical conference. Information presented at such meetings is considered early and should be confirmed through publication in a scientific journal after being reviewed by other experts.
