What Could Cause a Loss of Erection When Standing, and Is It Related to Low Testosterone?

When a man stands up, his body makes quick changes to keep blood moving smoothly. Sometimes, if there are problems with blood flow, nerve signals, or even a sudden drop in blood pressure, this can cause an erection to fade. This type of change is often linked to what doctors call orthostatic issues or neurogenic factors, where the nerves and blood vessels do not work as well during movement. This may also occur with cardiovascular disease or diabetes that is poorly controlled. Low testosterone, on the other hand, can make erections weaker over time or lower the desire for sex, but it is not usually the direct reason for losing an erection right when standing up. Instead, low testosterone is more related to overall erectile function and energy. It is important to look at all health factors, including blood flow and nerve health, when there is a change like this. If someone is noticing problems with erections when standing, they should talk to a doctor who can help figure out what is happening and suggest the best way to manage it.
