Signals from the brain to the male reproductive organs cause's relaxation of the muscles to promote blood flow to the organ and this allows the male organ to expand. Similarly, during ejaculation the reproductive glands contract and this forces the sperm out from the male organ. This action is controlled by the sympathetic nerves (T11 to L2) and the release of sperm is controlled by the spinal nerves which ensure control over emission and transmission of the sensation to the male organ. The reflex and the motor neurons coordination is responsible for such actions and in case, there is any injury or damage to internal tissues, the person suffers from factors such as decreased fertility, poor erection, decreased ability to ejaculate and altered brain response to stimulation.

A proper combination of sympathetic and parasympathetic nerves is responsible for erection and ejaculation; alternatively, spine injuries can cause low drive and reduce pleasure in such activities. Neuropathy and poor blood circulation to the male organ can reduce the strength and capability to get proper erection, and it is difficult to overcome erectile dysfunction using the conventional methods of cures, at the same time, one can use the ways of massage with natural oil to get harder erections.

The problem of low muscle strength due to motor nerve weakness causes muscle weakness, cramps and paralysis. Damage to the peripheral nerves can cause disruption in the message flow across the body to the extremities. The problem of erectile dysfunction can be caused by such nerve weakness which is further aggravated due to hardening of arteries, high blood pressure, diabetes, obesity, multiple sclerosis, intake of medicines (e.g. beta blockers, anti-depressants, relaxers, diuretics etc.), trauma to the genitals or the spinal cord or prostrate problem (due to endocrine disorders).
