The nervous system and erectile function
Sexual signals sent by the brain are transmitted to the penis via the spinal cord and nerves. This mechanism triggers the dilation of the arteries that supply blood to the penis, thereby initiating an erection. Stress, anxiety and certain neurological conditions can disrupt this process and lead to erectile dysfunction.
Erection: a vascular phenomenon
Blood enters the penis via arteries ‘opened by desire’, causing it to swell and become rigid. The expansion of the penis then compresses the veins to trap the blood and maintain the erection. When the arteries are narrowed or blocked, or when the veins can no longer retain blood properly, blood can no longer accumulate in the penis, leading to erectile dysfunction.
Hormones and erection quality
A healthy hormonal balance, particularly normal testosterone levels, supports sexual desire, psychological energy and erection quality. Certain hormonal disorders can impair erectile function.
Nocturnal and morning erections
A man spends long periods of the night with an erection without realising it, and usually wakes up in the morning with an erection. This phenomenon, which is independent of sexual desire, is considered essential for maintaining healthy erectile function. Any change in these erections may indicate underlying health problems.
The psychological aspect
Erectile function, psychological health and emotional well-being are deeply interlinked. Even when erectile dysfunction is of somatic origin (due to a physical condition), the psychological and emotional consequences often exacerbate the condition.
