What Factors Contribute to Weaker Erections with Age, and Is Testosterone a Factor?

Many changes happen in the body as men get older, which can lead to weaker erections. One important factor is blood flow. Over time, the blood vessels can narrow or become less flexible, making it harder for blood to reach the penis easily. Nerves also change with age, so the signals that start and maintain an erection might not work as well. Hormonal changes are another key factor. Testosterone, the hormone that helps fuel the desire for sex and supports strong erections, often decreases with age. This drop in testosterone can make erections weaker, but it is usually not the only reason. Other things such as medications, stress, or other health conditions like diabetes and heart disease can also play a role. In short, while lower testosterone is linked to erectile changes, the overall effect of aging on blood flow and nerve function is just as important. If someone has worries, it is best to speak with a doctor who can look at all these factors together.
